vortec 4.3l v6 1996 c1500

Besides the usual hop up parts available (headers, hyd roller cam, air intake, etc.) does anyone have any good tune up info for mildly hopping up the 4.3l v6 in a full size truck? Thanks!

Try a Performance Chip. If you have the CPI 4.3, it not much more you can do. If you have the TBI, you can add a Supercharger.

Also, GM Performance sells aluminum heads for the 4.3 V-6 that will help your engine breath better with modifications to you induction (K&N filter) and exhaust (headers, performance muffler).

I would not advise a low-tempature thermostat any lower than 180 degrees and stay away from high octane gas. The CPI engines injectors will clog with carbon when you incorporate a low temp thermo with high octane gas!

High octane (93) gas actually burns slower than low-octane (87) gas.

You could also do a custom job on the pleneum that could increase the flow of air with the mods mentioned.
