351w and 302

do the 351W and the 302 have the same intake manifold?

the reason i ask is because i have been thinking about converting my 85 f-250 to efi, it has a 351w and has a 4spd in it. if the intakes are not the same than what year and vehicle would i have to look for to get everything i need to do the swap? thanks for all info you can possibly get to me, as i yet do not know everything as i am in a 2-year colledge taking up engine machining, so i know most of this part but not the electronic stuff. thanks again!!!

I am pretty sure it doesn't it. They are almost always listed as seperate part numbers. And I am pretty sure the tall deck height of the windsor and i also think it is wider than the 302. Even though the heads can be interchanged with minor mod.

cdd5599, your right. The answer is no on the intake question.

351w and 302

Hello, no but the 302 uses a different intake than the 351w. The way I tell them apart is: at the rear of the intake between the surfaces that mate to the heads there is a curve. The curve is very close to the head surface on a 302, and an 1 1/2" or so away from the head mating surface on the 351w. I know, it sounds dumb, but go to a speed shop & look at some intakes for a 302 & for a 351 & you will see what I mean. The 351w is noticably wider. Good luck.
