Ive but a 4.3 as well and all I did was strap the engine to limit vibrations, and those headbolts are throw aways, anytime you take the heads off you have to replace them, sounds good, look at my s-10 clip and check out the sound and throttle response there
@extremedrivr i did use msd ignition and 8.5mm wires..But having issues with motor now. I reused my old headbolts in rebuild and i guess your not supposed too because they stretch so now i have slight head gasket leaks. Also on my rebuild i used Napa replacement motor mounts and i think they are out of spec. I think they are shorter than they were supposed to be or something. Ive had a vibraton since the rebuild and on my passenger side my header is touching the damn frame.
@monsterman27 >----> I have a 96' S-10 Super Sport with the 4.3 Vortec motor. and i've souped it up some. One thing that you should install is an MSD ingintion system like I did. It added 8 horsepower and 12 pounds of torque on the dyno. It even got rid of the annoying dead spot in from idle to 3,000. The 0-60, and 1/4 mile times have also picked up by about 1 full second(GTech Pro Meter). So here's my MSD setup > The Blaster 2 coil, The 6AL2(Digital) Ignition Box, and MSD's 8.5 MM Plug Wres.
actualy gm used to make a series of big 60degree v6s in the 2ton and up truck series. smallest one was 305 then went to 351 403 and up the 478. and had a 612 v8 and a 7oo+ v12. these are where the old gmc blowers used to come off of are these motors
Tim you read into the comment way to far,i know how large it is,it was a general statement of it being alittle v6,as in its not a v8.I dont own any obnoxious pick em up trucks.
not bad for a little v6? whats little about this motor. if your talking just in terms of six cylinders this is one of the largest available. or is anything smaller than the 454 in your obnoxious pick-em-up truck considered small?
@weewoodeal If your going to buy headers buy Gibson shorties you wont regret it trust me. They have a built in donut gasket and mine havent leaked anywhere yet. Deffinetly worth the money.

@watso64 >----> Technically! The 4.3 Chevy V-6 is bigger because its a 350 Chevy V-8 minus 2 cylinders.
