The 351c was only available for a very short time back in the early '70, but it was always a high output motor, so it is desirable for that reason. The low po 351M is often confused with the C because they look very similar, the 351C was never factory installed in trucks.
The 351w essentially picked up where the C left off and became one of the most common motors found in ford vehicles until the modular v8's were introduced in the '90's. It was built with both carb and EFI induction, and thanks to the popularity of the '90's mustang there are literally thousands of aftermarket high performance products available for the Windsor family of motors. For that reason this engine is also very desirable.

The 351c was built from 70-73 in a 2 barrel and 4 barrel version. Great engines the 2 barrel was best for street the 4 barrel loved to drag race. The 351w has been around 68 (I think that was first year) but the 69 4 barrel was the most desirable for most. Did you know that 351w could be built to 440 ci but the 392/393 is much more street able. I'm a big fan of both 351s even have one in my jeep cj.

Starting in 1974, Ford replaced the 351C with a 351M. This engine was built for the smog requirements of CA (1st generation).

If you change the heads would it still be concidered stock? I got Clevelands and Windsors. The Cleveland 4 bbl. is made for high rpm due to it`s big block chevy sized intake valves and big{and I mean you can stick your hand in there} intake ports. If I was building a pullin` truck I`d go big block. There`s no replacement for displacement,ask any girl.

Yes 440ci from a stock block but that's where it ends. Special crank, rods and piston's. I haven't built one to 440ci but I am in the middle building one 393ci. Eagle crank 351w rods and 302 pistons with .030 overbore. Check out eagle specialty products, I think it's eaglerod.com As for the clevor engine the Cleveland heads bolt right on the windsor block but you have to drill water passages into the head,some where around here I have the instructions for that. Also requires a special intake made by B&A (i don't think anyone else made the intake) and at one time there was special spacers around that would let you adapt a windsor intake but the B&A intake was much better.

Hmm Why oversized 302 Pistons as apposed 351w Oversized pistons or is it just a preference???..........What stroke do you need to hit 440Cid and how much of an overbore??? Would you say that taking it to this extreme displacement with the OEM block would compromise the engines structural integrity and life expectancy???? I'm not being rude or anything I love this sort of stuff

Because with the stroke of the eagle crank it would put windsor pistons out the top of the block, the wrist pins of a 302 pistons are higher in the piston. I don't know the specs right off hand for the 440ci, from what I have heard the stock block does fine for street and some drag racing but would want to move up to a aftermarket block for all out racing. There are several other ci configurations from the windsor block but I settled on the 393 because it was most affordable and will easily make over 400 hp in a mild setup.
