'89 Astro, 4.3L, TBI. Minor intake and exhaust mods. Rebuilt 700R4 trans (by me). Corvette servo, 0.5" boost valve, police grade 1-2 accumulator spring (shifts fast and solid). B&M stacked plate trans cooler. Bilstein shocks. Belltech sway bars front and back. New head unit, speakers and subwoofer. Needs paint and a new headliner.

1996 and newer 4.3s have different heads; the intake from your 1991 won't work. 1995 and older should work, no matter if it is from an S10, Astro, or full size truck or sedan. You may have to swap some parts around, like the belt driven accessories, but the engine itself should work.

Just swap whatever's different from your old one and it won't be a problem.
