I'm new to the forums, so hello all! So I've been a fan of Ford and Chevy, I know what a weirdo.. lol. I just bought my first project a 77 Nova. Well my buddy recently came into money issues and just sold me his 87 GT Fox hatch 5.0 roller. Well now I'm considering selling the Nova for the motor/trans. So now this would give me a clean slate. I want to make it fast obviously. I guess my question is; What motor set up is best bang for the buck. I really like a windsor or a 302. My dad want me to get a big block, but I'm a plumber and have 4 kids, so money is tight. I'm hoping to get around 3500 to 4000 for the nova. Also I'm sorry if this was posted in the wrong spot.[emoji51]
Fox/ford Noob!

You posted in the right place. Before anyone can give you solid advice what is your intended use for the car? What is your budget? What shape is the roller in?
I typically cringe at the thought of a first time owner starting with a roller for a project as it will typically snowball out of control and the car gets sold unfinished.

It's been sitting for 5 or 6 years in a garage. And before that it sat for a few years. The car itself is in amazing condition, very solid, no rust. Only thing that is missing is motor and trans. He also has a ton of extra goodies for the 5.0 that he was building. Which is the only reason I'm considering the 5.0. I don't really have a budget but should have around 3500 or so to get me started. He also threw in a cherry picker and engine stand. So if I start with a block it wouldn't be all that bad. My intentions are to just to make a nice fast car. No nitrous or turbos, all raw horsepower. I also have a plethora of gear heads who will assist in this project. I just wanted to know what advice I can get as far as what to do for an engine build. Thanks for the reply!!

Do yourself a favor and take his advice: it's the best you have gotten so far.
Far too many people put a dab of this and a dollop of that, and then wonder why the car doesn't run worth beans. Then they think off the shelf computer chips will fix their mismatched parts problem. It won't You have to have a plan for what kind of performance you want: Hot street. Street/Strip, Pure strip, Autocross or Road course. Each one requires a different strategy and a different set of components.. Mismatch the components and you’ll have a car that falls flat on its face when you demand performance.
Everyone thinks HP! HP! HP! and thinks that peak HP is what they need. Peak HP is great for a drag strip car when it has the proper gears and tires to get the car up into the high RPM range where it develops that high peak HP near the finish line. On a street car, that strategy will have Honda Accords outrunning you, because you will never get the engine RPMs high enough without running over everything in your path.
Here’ the strategy: Always remember that there are some tradeoffs in any engine combination. Most of us don’t have enough money to “have it all” as if it was possible by some masterful combination of parts and tuning.
The following recommendations are for 5 Speed Manual transmission cars without NO2 or pressurized induction, stock short block.
1.) Hot street: Broad flat torque curve, high velocity airflow in the intake and heads for best throttle response. Gears suitable for reasonable gas mileage and long road trips without excessive engine RPMs. Stand on the gas pedal from a rolling start to squeeze into that gap in traffic in front of you, and it jumps quick and hard to get you there. Max RPM’s are 5200-5500 RPM for best power. Lopey cams may sound cool, but run poorly in a low RPM street environment.
Use stock cam, stock, GT40 or mildly ported stock heads, Cobra or Explorer/GT40 intake, advanced timing, stock 19 lb injectors, stock fuel pump. Use some good 1.6 or 1.7 ratio roller rockers for extra punch. Use a King Cobra clutch, with stock iron or steel billet flywheel. MAF cars can use a 65 MM TB from the Explorer intake manifold and a 70MM MAF from a 94-95 Mustang. Drive train: 3:55 gears with soft tread compound tires. Use some Ford Racing unequal length headers, stock 2 1/4” cat pipe and some mufflers that don’t drone or get too much attention from the law enforcement or neighbors. The stock computer will handle all this with no problems and doesn’t need any help in 90% of the cases. No skinny or grossly undersize tires for the front: remember you still have to stop quickly in traffic. Make sure all the rubber bushings in the front and rear suspensions are in first class shape. Leave the emissions equipment intact and working. Removing or disabling it won’t get you any more HP or performance. Do not convert to carb or remove A/C: either one will reduce the resale value. Carb conversions cannot be titled for street use or get tags in some places. They definitely won’t pass smog inspections.
Street/strip: A little more slope to the torque curve with a gently sloping peak. Use slightly larger port volumes on intake and heads for more peak HP. Uses 3.55 or 3.73 gears to get the RPM’s up into a higher range quicker. Be prepared to sacrifice some low RPM throttle response in exchange for high RPM power. This by necessity will be a Mass Air or Mass Air conversion on 86-88 5.0 Mustangs, since stock speed density will not run well with the changes in engine airflow. Don’t get too crazy on any one engine part since you still have to drive the car on the street, and a mismatch can make street driving miserable.
Use stock or mild aftermarket cam, Ported GT 40, or 165-180 CC port volume aftermarket aluminum heads. Use a Trick Flow, Edelbrock Performer or equal intake manifold. Take a 73 MM aftermarket MAF calibrated for 24 lb injectors, and 24 lb injectors, 155 LPH fuel pump, Kirban adjustable fuel pressure regulator. Be prepared to shell out some $$$ for a custom burned chip using data gathered from a dyno run. Mass market chips will not get the job done. Use some Ford Racing unequal length headers, aftermarket 2 1/2” cat pipe and some mufflers that don’t drone or get too much attention from the law enforcement or neighbors. Drivetrain: expect the stock T5 to fail, so save your money for a super duty 5 speed trans. Tremec 3550, TKO 500 & TKO 600 are the best choices. Different gears in a stock T5 case work for some, but there is only so much power you can pass through a T5 in race mode before it breaks, even with stronger gears. Next are the Chassis mods: full length subframe connectors, different springs, different shocks, aftermarket lower and upper control arms with rubber or urethane bushings. Buy all the parts from someplace like Maximum Motorsports, Griggs or Steeda as a kit so that you know that all the parts fit and don’t argue with each other. Carry spare tires and wheels for the drag strip: skinnys for the front and drag radials for the rear. No skinnys for street driving! Over 85% of the breaking power is generated by the front tires, so skinnys won’t do the job in a panic stop situation. Disconnect the front anti-roll bar at the strip; reconnect it before you drive home. Leave the emissions equipment intact and working. Removing or disabling it won’t get you any more HP or performance. Do not convert to carb or remove A/C: either one will reduce the resale value. Carb conversions cannot be titled for street use or get tags in some places. They definitely won’t pass smog inspections.
Strip only: High RPM, High flow heads (185-215 CC port volume), wild cam, high flow intake manifold, 70 MM or larger TB, 80 MM or lager MAF, strip everything out of the car that doesn’t make it go faster. Carbs are OK if that’s what you want, but remember that as the temp/humidity/ barometric pressure/altitude changes, you have to re-jet and readjust the carb. EFI eliminates most of that with its built in compensation or you can tune of the fly with a high end Motes or Tweecer system combined with a wide band air/fuel ratio meter. Use custom headers, dumps and minimal mufflers. How fast you can go on 5 liters is a function of the skill level of the driver/mechanic and the size of your wallet.
TRAILER the car to the race track since it won’t be legal to drive it on the street. Drag slicks in the rear, skinnys up front, use 3.73 or bigger gears (4.xx) in the rear axle. Since you won’t be driving on long trips, the big gears with work with the high RPM power curve to get the best results. Drivetrain: TKO 500 & TKO 600 are the best choices. Different gears in a stock T5 case work for some, but there is only so much power you can pass through a T5 in race mode before it breaks, even with stronger gears. Next are the Chassis mods: full length subframe connectors, different springs, different shocks, aftermarket lower and upper control arms with rubber or urethane bushings. Buy all the parts from someplace like Maximum Motorsports, Griggs or Steeda as a kit so that you know that all the parts fit and don’t argue with each other. Remove the front sway bar, put an airbag in the rear spring of the side that spins the tire the most. Plan on a roll cage if you are truly serious about going fast: most strips will require it once you get to a certain ET range.
Autocross is a combination of Hot street engine and street strip chassis prep. The engine must accelerate quickly from low RPM and needs a broad, flat torque curve. Next are the Chassis mods: full length subframe connectors, different springs, different shocks, aftermarket lower and upper control arms with rubber or urethane bushings. Buy all the parts from someplace like Maximum Motorsports, Griggs or Steeda as a kit so that you know that all the parts fit and don’t argue with each other. Most of the time you’ll never hit third gear, so some 3.73 or bigger gears (4.xx) may help a lot. You’ll have to spend some more money on brakes since it kills brakes quickly. Rear disks, larger rotors up front, stainless steel brake lines, different brake pads. A 87-88 T Bird Turbo Coupe or SN 95 rear axle will be your best bet. Autocross will severely strain 1st & 2nd gears, so your T5 may take a premature dump. Save your money for a super duty 5 speed trans. Tremec 3550, TKO 500 & TKO 600 are the best choices.
All out road race is the most difficult of all: an engine that will run at high rpm hour after hour and never fail, yet pull hard out of the hairpin turns that will require a lot of torque at lower RPMs. In my opinion, guys that can successfully build a winning road race engine are the cream of the crop. Top this off with a chassis built for strip only duty, but with changes to the settings of springs, tires, roll bars brakes and shocks. It’s a whole other world of racing.
You’ll have to spend lots more money on brakes since it kills brakes quickly. Rear disks, larger rotors up front, stainless steel brake lines, different brake pads. Air ducting to cool the brake rotors will be a must. The brake rotors of cars on a high speed road course glow red after several hard laps of racing. Drivetrain: TKO 500 & TKO 600, and T56 close ratio are the best transmission choices.

If, and only if the wiring, ecu, and interior are completely intact should you start on this. The time and money you will spend putting this car together otherwise would far outweigh its potential worth.
If, everything is there and you are planning on starting with 3k dollars from the sale of the nova I would take jrichkers advice and personally go hot street in the form of a very mild gt40 engine from an explorer. These can be had for about 2-400 dollars. Mate that with the tranny of your choice. Altogether plan on realistically spending close to a grand on a good reliable power train. So take a third of your budget off the table right now. It's been sitting open so your fuel system needs to be gone through and likely replaced. Lastly I would HIGHLY suggest replacing or repairing every piece of your brake and suspension system. I hope you got that roller cheap because to build a solid, dependable car you will likely have 5-6k minimum into your car.

Street/occasional strip is probably what I'm going for. Fortunately for me the last thing he did to the car was rotors/calipers/brakes. I will start using my Facebook pages and craigslist to see if I can't get an idea of what the gt40 is going for around these parts. Thanks for the help so far.

To the best of my knowledge, Ford does not make any equal length headers.
Equal length headers are harder to install and keep from burning up the spark plug wires.
Why just Ford headers? Because the are made of high quality materials and will last a very long time,

Depending on budget and expertise you might want to look into a new coyote 5.0 swap. Not a cheap proposition but you'd have a very cool build and might actually retain some value if you sell it down the road. Not saying you'd get what you paid for it though. Most of these cars don't retain much value even with nice typical "hot rod" upgrades. A coyote swap would include all new wiring/ecu etc. but expect to pay anywhere from 8-20k for the complete project(it really depends if you buy a new crate motor,new trans,etc or a mix and match of new/used parts and how much you can do the work). A well done coyote swapped fox body should make 375-425 rwhp,pull down 20+mpg,and drive like a new car. But if you only have 5-6k or whatever you're going to be hard pressed to get a drivetrain put together. So when we ask your budget it really matters for the type of advise/opinions
I don't really have a budget, like I said. I am selling my Nova to get me started for roughly $3,500. Hopefully this pays for my motor and trans and I can just add as I go. I've been reading on the 351w bored to 408 is relatively inexpensive and one of the best bang for your buck builds. I want around 450hp with no nitrous or chargers.
Affirmative. You could build a 302 based engine for what just the heads on that beast will run you.
