Took my 69 c10 for some dynojet time.

I did some top end changes on my truck. Reinstall stock intake, another Qjet and Summit cam. Basiclly it's a stock Pontiac 400 about 8.9:1 comp ratio now. Broght a truck back to my buddy's dynojet shop. Made some pulls. Air cleaner was about 10hp and open exhaust another 13 hp. My main consern was an air fuel ratio. Best pull at the wheels was 325hp at 5200 rpm and 358 max torque at 4200 rpm. All on California's piss poor 89 shell gas. Might get better exhaust later on.
