    Engine What's The Best Rpm For 302?

    I think your post was clear. I disagree with your statement though. I think that there are too many variables to say that XX RPM is the way to go for X size bore to optimize fuel economy. Brake specific fuel consumption is not that simple.

    Squeaky Front End

    I always had trouble with squeaking from the upper control arms - until I went to Opentracker roller bearing parts. Even with new Ford parts it doesn't take long for a squeak to develop. I think I read someone on here recommend removing the spring to take the load off the UCA so that the...

    Engine 289s W/ Gt40 Heads. What Pushrod Length Did You Use.

    You always want to measure the correct pushrod length. Spend $20 on an adjustable length pushrod checker, mock up the valvetrain, and then buy the correct one. Tolerances of the components parts are quite loose. What worked for one person cannot be assumed to be correct for the next...

    Bell Housings For Manual Transmission

    Yes you can put an 11 inch clutch into a T5 bell. The Fox Mustangs started with 10.5 and then went to 11 inch. The flywheel is 157 tooth. Fox flywheels were 50 oz imbalance and you want a 28 oz for an early 351W, so you can't use a stock Fox flywheel.

    Engine What's The Best Rpm For 302?

    :nice: Yes, experimentation is the key. My Fiesta actually is over 3,000 rpm at cruise 75 mph and gets 39 mpg. Seems like a lot of revs, but it works.

    Engine What's The Best Rpm For 302?

    The real answer depends on cam, compression ratio and other variables too numerous to list. Determining the gearing for best fuel economy for one particular car and driving route requires iterative experimentation. The experimentation would have to be conducted in a laboratory setting because...

    Makes a subtle difference, no?

    Engine What's The Best Rpm For 302?

    About 1,500 rpm with your current gearing is better than trying to run the speed limit. You want to run between 40-50 miles per hour. That will reduce drag from wind resistance significantly. Also, the skinnier tires the better with very high air pressure to minimize rolling friction (I...

    FE Build 428 Cj Heads On A 390 Block

    Yeah I agree bigger bore bigger stroke = better, especially for a truck motor.

    69 302 Engine Rebuild Problems

    It's very hard to know the problem without looking at the parts. However, since both the previous owner and you had the same problem I tend to think that there is a defect in block, heads or timing cover that is causing it. I wouldn't think both of you bought the wrong gasket or made the exact...

    '72 351c 2v Upgrade Help

    The basic design of the 4V was first used in the Boss 302, so Ford seemed to think that the 4V head was a good performance head, even for smaller than 351 cubes. I think that Ford winning the Trans Am racing series with the Boss 302 shows that the heads were great for racing with 302 cubes. 4V...

    '72 351c 2v Upgrade Help

    Good advice! Although I probably wouldn't spend the money for new 2V valves. If you really want 2V the valves are a good idea to keep from destroying other parts. :)

    '72 351c 2v Upgrade Help

    They also sell a thing called a "TORNADO" which is supposed to spin the intake air and improve performance. I won't try to stop you from buying one but I also will not recommend it. I think some of this is an opinion thing, but 4V heads are in no way too big for the street. If the engine is...

    '72 351c 2v Upgrade Help

    Edelbrock air gap is a good choice for an intake. It's taller than the stock intake but I think it will fit under your hood. You might consider headers too. Upgrading the exhaust will also improve performance. If it were mine I'd go 4V though. For a mild 351C Holley will recommend about 600...

    Motor oil smells like gas

    I had this happen on my '80 Ford F-250 plow truck. Fuel pump diaphram failed and put a lot of gas into the pan. The old school fuel pumps fail a little more often with modern fuel eating the rubber parts. At least it's an easy fix. Change the oil and the pump - away you go!

    Geting Ready To Start On My 69 Shelby Replica -et Five Spokes?

    I agree that there are a lot of torque thrusts out there, but I still like them. There's a reason why there are a lot of them out there. They look great. I have a chrome set on my black convertible and they look really good. They are also reasonable since so many people like them. There...

    Weird Idle Issue.

    It sounds to me like you might have a couple problems: 1. Ignition timing 2.Wiring issue that prevents the car from starting normally 3. Possible vacuum leak or carb problem preventing normal idling. I would diagnose the wiring first, because you can figure it out without the engine running...

    392 Ci Ford Racing - Distributor Gear Wear Out

    I would use a steel distributor gear with a roller cam. That's what Ford did in their production cars. Don't use the cast iron, it's for hydraulic flat tappet cams. I'm not sure why you are using bronze. It's soft and will wear out. I suppose the bits of bronze in the oiling system are not...

    Is It Easier To Put The Engine And T5 In Seperate, Or Attach Them, Then Put It In?

    I prefer separately, but I don't have tools like a lift or raised areas like a factory production line. I've done it both ways and I end up scratching something or bumping something when I do them together, even with someone helping. I think if you have the right tools and you get the car up...
