cooter48c Posted November 22, 2016 Report Share Posted November 22, 2016 I have a 1999 Chevy 1-Ton with a 7.4 liter gas, been trying to find someone who can help me add horsepower/torque to this big block. Guess I am spoiled by all the diesel's with 400 plus horsepower. If anyone knows of a shop or company that still makes upgrades on older trucks like this please help. I know the best thing would be swap the motor for a diesel, 4wd comes into play ! A cummins is to long. But I am willing to look at a swap if someone has experience in that area.
