Just rebuild my 302 , my truck is a 96 but I used 91 block and used 96heads intake computer and etc, its runs bad under a load and shuts off I have replaced almost everything only thing I can think of is that I used 91 exhaust manifolds and they have no o2 sensors will this case the problem not having any o2 sensors hooked up ??

Did you switch the computer to a 91 without o2 sensor input or did you keep the 96 computer?
