1999 Chevy Blazer 4x4 4.3L Rebuild
 

I have a 1999 Chevy Blazer that i plan to pull the motor and rebuild and was wondering if any one had ideas what i should do. I would like to get around 400-500 HP but i dont know where to start

sorry not 400-500 around 200-350 or so

are you trying to swap or make that power out of the 4.3

I already decided what i plan to do since i cant upgrade the cam due to the computer timing. bore 30 over, balance pistons and connecting rods to the same weight so the engine will be internally balanced

you can also port the intake,heads, and exhaust, not to many things that you can do to make power on other cars really work on the blazers like cai, headers, ignition al that stuff dont really work all that well
