I have a K2500 Suburban with the 7.4 vortec engine and will soon be doing some upgraded so I figured I might want to document the gains with real proof. Today I ran a few times on the dyno to create a baseline. The truck has 210,000 miles on it and runs great. I wanted to run it completely...
Sorry, if this has been discussed recently, but i couldn't find it. I have a 96 K2500 Suburban 7.4 and I'm trying to find long tube headers for it and I am having no luck. Does anyone know where to find them. Thanks.
