Re: 3,4 camaro engine swap
Check out the "can't find a 2.8" thread a few posts down, most of the answers to your questions are there. I know several guys who have done the swap with great success. A friend of mine did the swap into his '85 Blazer about 3 years ago; he loves it. He's smoking stock 4.3 Blazers easily. He put the Edelbrock Performer 4-bbl manifold, Holley 500 CFM carb, headers and roller rockers. Runs real good.
A lot of '89-91 V6 Trooper owners are doing the swap, too. Most of them regularly post at www.ITOG.com
, the Isuzu Trooper Owner's Guild. The combo of 4:56 gears and 160 HP really moves out nicely! A few have done the wiring harness/etc/etc swap to retain the Camaro's EFI system, but most have just bolted up a larger TBI (Holley Big-Bore or GM stock 4.3), along with boring the intake to suit. With TBI and a 2-1/2" exhaust system you are still getting more HP than a stock 4.3 TBI motor. Hope this helps.....ed
