    351W Build

    A forged crank in a 351 is a waste of money unless you plan on making over 1000hp or road racing. I can't remember ever hearing about one breaking. I would not worry about rod ratio either. Some of the most powerful engines have what most would consider horrible rod ratio. I will take cubes...

    welding perches/setting pinion angle

    If it is a driver you would be fine copying the 8". I it will be making good power and using sticky tires you will want the pinion down 2-5* compared to the trans.

    351 Windsor hp limit? head options?

    There is nothing wrong with a C block for what you are doing.

    351 Windsor hp limit? head options?

    Especially when the weight is so near the center. I would not hinge a decision on that. If you want a Cleveland, build one. There are a few things that can trip you up, but nothing major.

    351 Windsor hp limit? head options?

    The cost of the windsor + $2000 = clevor cost.

    351 Windsor hp limit? head options?

    I have never heard of a windsor block cracking below 800hp. I also think that World Product sbf heads are probably some of the worst non Ford heads made. A clevor does have some cool factor, but they are not cheap or easy. Cleveland heads can make great power too, but the ports are big for...

    351W Build

    You should look into a 408. By the time you turn the crank, buy pistons, rod bolts and resize the rods, you are getting close to what a stroker rotatating assembly would cost. 500hp with a 351 is not too hard these days and even easier with a 408. The only reason I built a 351 vs a 408 was...

    Need help tranny ?

    Where are you finding C4s with 5 and 5. I have never seen a C4 with 5 in the direct, and very few had 5 in the forward. My MII C4 lasted about 50 passes with just a valvebody running 6.70s in the 1/8. It broke 2 8" rear ends before the direct clutch gave up. The bell housings don't work well...

    351 Windsor hp limit? head options?

    A windsor block will take well over 500. I think 850 is more like it for a 351w if you don't rattle it.

    what's the difference

    Also the 67 has 4 holes for the strut rod so they fit either side. 68 has 2 holes

    what's the difference

    The strut rod is straight on a 67 and the 68 has a bend in it. The holes in a 67 for the SR are angled and the 68 are inline. You need 68 strut rods for 68 lca's.

    Help on Ford C4 rebuild

    Mr. Din, I originally built my C4/C5 from info I learned from C4 Transmissions - Ford Muscle Forums : Ford Muscle Cars Tech Forum including self modding the valve body. I was never real happy with the way it shifted to 3rd at light throttle. When stepped up the power of my car I decided to...

    I would consider a stock VB with a transgo kit.

    2.25 or 2.5 inch exhaust.

    If you look at the original poster's combo, you will see it was built for performance. Why would you put an exhaust system for putting around on a motor that makes power over 6000rpm? Most people size their exhaust for the most it will need to flow, not what it flows most of the time. I...

    That sounds like a valve body problem.

    351W Stroker vs 390

    Physics, it's not just a good idea...it's the law!

    Help on Ford C4 rebuild

    I will start by saying that kit will probably work fine at 300hp. It is basically a stock rebuild kit with shift kit. Most C4 builders are not thrilled with B&M shift kits. Transgo shift kits are what most recommend. If you plan on more power down the road you should look into the 500hp kit...

    2.25 or 2.5 inch exhaust.

    His motor makes over 600hp. The chart in the link above does not even go that high. Blown65, did you dyno your motor with your exhaust?

    2.25 or 2.5 inch exhaust.

    What about an 800hp 351w?

    2.25 or 2.5 inch exhaust.

    I would do 2.5". Down the road you want N2O or a 347 with good heads on it and have to buy again if you go 2.25". I wish I had done 3" on mine.
