Hey all. I just picked up a '91 350 from an ex-police caprice, and I'm supposed to be swapping it in place of my '88 350 today. The trouble is, I'm starting to think the '91 heads are much different than the '88's, which is going to make it a mess doing a direct swap (I'm driving the truck into the shop and need to drive it out at 5pm when they lock up!). Everything in theory was supposed to be a direct swap, with the possibility of moving the '88 intake onto the '91, but that will get really complicated if the heads aren't identical!! Does anybody know the exact interchangability of the stock TBI intake's between an '88 350 and a '91 350?? What will I need to modify to make them gel?? Time and money are objects here!! I have access to a parts delivery place, but 1-2 day wait on any special order parts (I.E. not-stock), so "get a new computer or harness" is not a possibility!! What are my real-time options here? Thanks in advance for any replies!! Ratch CK5 album Your ad here.
