me and my brother where talking and he said we could build my 89 4.3 v6 262 with a vortec intake manifold. i was wondering what problems would i have doing this what parts would have to be changed. has anyone done this tbi to vortec change before?
has anyone swapped over a 1989 4.3 v6 tbi engine from a astro to a chevy s10 from around these years and what problems or concerns did you have when you did this. I'm in the process of doing this now and i wanted to know if anyone knows if i have to change the accessory brackets or anything else besides the engine and transmission mounts? what about the air cleaner does that have to be changed to? thank you for your replies
Yes, that swap is done quite often. It would be a direct bolt in. I'm assuming both 4.3s are TBI? you would use the air cleaner from your s10. If mine were TBI I wouldn't be able to resist from making a clean polish/chrome air cleaner fit the TBI.

I don't have any personal experience with the fuel injection in the first pic, but just by looking at images online it looks as if that that gen of Vortec induction does bolt on using the older style bolt pattern. I am inclined to say you can use that F.I. on your current heads
