so if a 4.3 has only 140 hp...or even 190hp..and my 22r has over 175...and weighs a few hundred pounds less..why is everyone putting them in Toyota's?? that would be stupid....according to chevrolet:
"equipped with the 4.3-liter V-6 engine, rated at 190 horsepower and 250 lb.-ft. of torque. The five-passenger Blazer has, with the rear seat upright, almost 30 cubic feet of cargo room. Folding the rear seat forward opens up..... " so i was thinking torque when i comented earlier, so given those numbers, and what aaron has done and is planning on doing, i think a safe est. would be 215- 225hp, 260-280 ftlbs. tq.
which again makes me wonder why people do this swap seeing as its not all that difficult to make a 22r produce 200 hp or close to it, i have owned one that was still very streetable at nearly 200hp and weighed alot less than a 4.3....... 
regardless, good job aaron, and that thing better be in the truck this weekend!!!
dont make me come down there jr. 
OK those numbers sound a little better. The reason I think people are swapping those engine in is more of the torque output and because its less expensive to put them in. Yes they do weight more but they do produce a bit more torque. The 4.3 vortec that is going in my buggy is normally the usual 190 horse but with just the smog crap taken off it will produce more than 220 horse. Thats with just removing parts. I only have $900 into my engine and when I rebuilt my last 22re it was more than $900 and I was only going to get around 160 horse and ? torque.
