    I Have an 87 GMC Jimmy, I just swapped the 350 block with an 81 block, everything matched up except oil pressure and some kind of coolant sensor. I've been told that the cam I have in the new block is aftermarket and my computer cannot be modified to settle down my idle (which is idleing like crap right now) anyone have ideas? (I have brought it to three local mechanics who cannot figure it out)
