Any 5.3 motor results
Was thinking of doing a budget motor in a lighweight race car for the hell of it. Does anyone have any dyno numbers on a 5.3 stock or with mods. What is the compression out of the factory with these.

for starters i know most 5.3 trucks dyno in the 220-240RWHP area stock. Deff have seen more than a few bolt on cam trucks making WELL into the 300s at the wheels through an auto.
