Hi everyone. I know this has been done thousands of times, but I would like some input before I forge ahead and have to start reinventing the wheel! My 94' Sierra has @ 207K miles on it and is tired. It runs fine, but is weak. And the trans is definitely going south! But I will fix that later. My question is: What is required to run my stock(or probably upgraded some) TBI, and all my stock accessories,i.e. air conditioning, power steering...etc. on a Vortec 350? I have read some info, but I would really hope some of you guys that have done this could give an idea what I would need to do to make the swap. Before suggestions of 383's and LS swaps start rolling in, I'll just say I can get a deal on a Chevy replacement engine in a crate, and even the budget 383 motors I have put together, after machine work and parts will surpass the cost of the crate motor. It's purely a matter of economics. I have two hot rods already, don't need a pickup that will be a pain in the ass too! lol I do all my work myself. I bought a beautiful 1994 Z-71 in 1996, only had 20K miles on it. Traded it in on a new 1998 K2500HD with a 454, and drove it until we bought a new 2015 Z-71! I had to do a cam swap on that 7.4, if anybody has a cam go bad I could tell you about that experience. I know most of you guys on this board know these trucks very well. I hope somebody can give me a laundry list of stuff I i will need to do , and watch for. Thanks in advance, I'm looking forward to hearing from you!
