My brother runs an all stock 94 c1500, and wanted to race on Friday night. I beat him fairly substantially. Considering its relatively the same drivetrain other than mine is 4wd, I thought this was impressive. I'm also on 33" tires. Both of us are auto, and have 3.73 gears (he swapped his a few years ago). So I was telling my coworker who I bought the yukon from, and he said "yeah, having the heads ported, and larger valves, and heavier valve springs installed made a huge difference." I didn't know that this had been done. Eh, not vortech heads, but they will do. Ha ha
