Bore out the big block....remove extra weight!!

Actually, what are you trying to build?? If it is a sometimes cruiser/racer that people say HOLY SCHNIKIES LOOK AT THAT MOTOR!!...then go with a 4.6 or a Big Block. If you are building a daily driver....go with a small block and maybe add fuel injection, electronic ignition for reliability.

Big Blocks make peoples eyes come out of their heads...."No way did you make that fit"



Also remember: Horsepower takes fuel no matter what kind of motor you have. And, my 429 is getting 10-12 mpg.

what about a 94 or 95 cobra 5.0? will this fit into a 65 without modifying the shock towers? what about 96 cobra? I would be interested in putting one of those in my car!

I apologize, please don't take it personally. I just think that if you do the math, fuel economy might not matter as much as you think.

How many miles a year? How much change in mileage? Estimate the cost. If you drive 5,000 miles a year and go from 10 mpg to 15 mpg, you're saving $334 per year at $2 per gallon of gas. Don't spend 5,000 dollars to gain $350 a year, that's all I'm saying.

Get the motor you want. I agree that the new motors are really cool. They are also way more reliable and require much less tinkering than an older engine.

Tinkering and working on the cars/engines is half the fun. Otherwise we would drive hyundais.

well, after i sell my '66 coupe, my plan is to get a '67 convertible and use it as a summer car. i want to build it up so it handles well and has a good strong engine (400 hp give or take). i want it to be more of a sports car then a drag car.
since the cammer is out becuase it's expensive/won't fit, i'm thinking about the '87-'93 5.0L from ford racing (345 hp, would use EFI), and maybe adding a paxton supercharger.

do any of you know of any downfalls of this engine? or if i would have to do anything to it so it could handle the paxton?

would it be worth it to go with a 351 instead?

I disagree. My main reason for driving a Mustang is the style I like. That's why I purchased a Pertronix ignition. How many people here have gotten rid of their points? I do enjoy tinkering, but I don't want to tinker with the same component repeatedly.

I REALLY like things that work reliably. My starter solenoid died the other day, which is a fun breakdown, because you can still start the car and drive away. Other things, even simple ones like a bad ground, can really spoil your day.

Oh and my carb needs some adjustment.

Yes, the 94-95 Cobra engines will fit. They are still 302s.

technically no such thing as an 86-89 cobra engine. The SVT cobra started in 93. The Cobra 5.0 in the 94/95s is the 5.0 HO with GT40 heads,upper/lower intakes, and some other minor stuff I believe. I would just get a low mileage standard 5.0 out of an 87-93 mustang (easier said than done, I know) and build that up. With EFI and some boltons, they can be very fun motors.

For a sports car-type project, I'm not sure I'd do a 351 (though they aren't that heavy, and would work). A 289/302 would do fine.

Duke: you want a 400hp car but still have good fuel mileage?? If you aren't racing what do you need 400hp for?

I am not trying to stir the pot, I am just trying to understand.

For "merging" on freeways. Why don't you need 400hp.

Exactly

i don't want good fuel economy, just not terrible. I figure 400hp (can get this from supercharged 5.0?) should be quick enough to humiliate the local imports, and not too terrible on the fuel, but i could be wrong.

Yeah have you ever driven a 400 rwhp car. You need some serious rubber out back and some easy driving because that thing will break traction so quick.

I really doubt you need anything more than 300rwhp on light body stang.

OK. That is a little more reasonable. Also rememeber that HP takes fuel AND reliability takes $$$.

400fwhp * 15% power loss = 340rwhp (conservative)

Anytime you start making more that 1:1 hp-CI power ratio you are into some money. Yes, you can do it, it just takes time and money.

BTW: are you coming over for the Mustang show on Memorial Day weekend??
