The 4.3 carb versions were 2bbls. approx 180hp. the TBI was 195 or so, the vortec 210'ish. That motor was designed for the pickups and Astro vans. 85-86 or so was first year, replaced the 250 I6 in the 1500.
I had a '92 K1500 with the TBI 4.3, IIRC it was only 160 hp or so. But it pulled a 4K trailer OK with 3.42 gears and a 5 speed manual, although getting it rolling was not great. Later I had an '84 C20 with the aformentioned 4 barrel 5.0, and it was a gas-guzzling gutless turd. The TBI 4.3 would pull the same weight better, as would my 4.0 Exploder.
