i have an 83 stang gt with a carbed 351W that is in need of a rebuild, but the other day i found a parts stang with a good running EFI 302 HO that i can get for cheap

would the 5.0 manifold work work on my 351W? or would it be easier to swap in the 302? i kinda don't wanna lose the mods i have done to my 351w or downgrade to the smaller engine

so here's teh question how hard is it to convert from Carb to EFI? what all would i need from the donor stang? and is it worth it?

thanks in advance

Im thinking ur gunna need from the donor stang some stuff.. The intake should just swap right over no prob, u may want to upgrade that tho. Also you will need the computer, engine harness, computer harness, o2 sensor harness, and i think that may be it. Im not sure if it will plug into your dash harness, if not you will have to change that over too... Ive done them all, and in a less then 2 days i got the entire cars harnesses all swapped over... Its up to you if you want to do the work .. Hope this helps good luck!!

my 351 intake is around 2" wider than my 302 intake manifold. not sure if yours is the same as mine but might not work

thanx for your help guys... i'll try to find a stock 302 EFI manifold to test fit it so i don't haul the car up here (2 hours away) and have it not fit and decide not to do it... i appreciate it
