Hey guys got some questions. I swapped a 350 into my Dad's 95 2wd Dually. It had a blown 454 in it. The donor 1500 that the engine came out of has a 4l60e. Which computer should i use? Will the half ton computer run the 4l80e or will the 454 computer control the 350? Also I havent hooked up the exhaust yet would open manifolds cause the knock sensor to throw an elctronic spark control error code? I've currently got the original 454 com puter in right now. Thanks for any help!
