OK I know there is alot of posts on this, but I have still not found the info I need.
I have 93 1500 Sliverado with the Vortec 4.3 5-speed. I plan on buying a 88-95 350 block so my pullys and everything will hook up fine. Then I was planning on putting on the GM performance Vortec heads from jegs, and a stroker kit from eagle. Then an eldelbrock intake made for the vortec heads, and then I figured the 96 and later Throttle body would work on that intake. But the the thing is, is my computer set up going to work with the throttle body and intake and all that. I know I will need a new ECM, but the 96 and later have a completely different computer set up don't they.
So if this is true does that mean I would have to get a intake that would now take advantage of the vortec heads and try to find a 88-95 Throttle body unit. Then I also need to know what block I need, is the 88-95 a four bolt main 2 piece seal. Thats my guess. If I could get any info that would really help full, I would like to run the vortec heads intake and the 96 and later Throttle body, so if somebody knows of a wire harness that I could maybe get that would be cool too.
If i get this done I'm going to document the whole thing and post it on the internet to help others like me, haha.
PS anyone want to buy a perfectly running 4.3 vortec.
