new to the Ford Family, need help!

Hello folks! That's right, just purchased my first Ford. I bought a 94 GT. It has supposedly had a 351W put in place of the 302. It still has fuel injection (says Ford Motorsports on the upper plenum), 24 lb injectors, and a hot sounding cam. Without pulling the engine and tearing it apart, how can I determine if it really is a 351W? These hosses are so different from the SBC's I am accustomed to playing with.

Any help will be greatly appreciated.

The 351 Windsor Motor is actually taller and wider than all other Windsors.If you know of someone who has a 289-302 or something,then maybe you can compare measurements?

Re: new to the Ford Family, need help!

Maybe dyno it and see what the torque is?

I was mucking around with a mate (legally) yesterday: He has a 351 Cleveland backed by a T5 + 3.23 diff, I have a 302 Windsor with the A4OD + 3.27 diff. I have a bit more power than him, and he has a lot more torque than me (both engines are mildly modded). Needless to say he slowly pulled away from me

What I'm getting at is, if you get it dynoed and it has a torque reading that's much higher than what a standardish/mild 302 should put out, that should give you an indication that it's a 351W, or at least a stroked 302 (347?).

But do what Lukeh suggested for the best result: find a mate with a 289-302 and compare the dimensions. It's free, it's quick, and it's decisive.

302 27-1/2 long 20-3/4 height 18-3/4 width

351W 27-1/2 long 23-3/4 height 21 width

So its 3 inch's higher and 3 1/4 wider...
I hope my Canadian / French translation came out o/k...

Plus a 351 has 3.5 inch stroke..Simply pull spark plug out and measure from tdc to bdc...If its 3.45 it has a 347 stroker crank in a 5.0 block...

3" = 5.0 [302ci]

3.25= 5.4 [330ci]

3.45 = 5.6 [347 ci] .030 over bore...
