How would GT40 heads work on a 351 windsor (EFI), much improvement or none at all. I am guessing they would work pretty good condsidering the 302 and 351 use the same heads ET7E's. Also does the cobra intake out flow a stock 351 intake (again EFI)

One more question... what cam does a '96 351 windsor use?

thanks for any replies

GT40 heads would be a good improvement over the stock heads. Those are what are on the GEN 1 Lightning 351W's (93-95). BUT you need to change intakes, too. The best way would be to use the Cobra/GT40 351W upper/lower along with the heads. A cam change would be a good idea as well. Just remember your motor is speed density and not mass air.

I don't know the specs on a 96 351W cam. It'll probably depend on what it was in (ex: truck or van).
