351w fitment

I’m sure this has been asked over 100 times but I can’t seem to find the answer going through as far back as 50 pages. I have a 1966 F100 without a tired 352/c6 combo, and I'm going to go with a 351w/c4 combo that I have on standby. Are any of you having fitment issues with the 351? I plan to use a 5.0 mustang shorty header of some sort and I'm currently looking for a set of 68/79 302 engine perches. I just want to make sure that I'm not going to have to grind or notch anything just to make it work and run the exhaust.

No 302's in F100's until 1969.

Engine supports aka towers/stands/perches: 1969/79 F100 302; 1975/79 F150 302, same as 1977/79 F100/350 351M/400 2WD

The 302 did come out in 1968 but in cars only. The truck got it in 69 two full years after Chevy came out with a 302. Yep I swore!

Furthermore, and just as a point of odd information, both Chevy and Ford's 302s have a 4x3 bore and stroke.

And a cheating way to figure out cubic inches or stroke on ANY V-8 with a 4.00 bore
If you know the stroke add 2 for cubic inch
If you know the cubic inch subtract 2 for stroke.

4.00 x 3.00 you add 2 like this (remove decimal) 302
4.00 x 3.25 = 327
Or 327-2 = 3.25 stroke

That math would work for a 400 c.i. Ford
