my 69 on a dynojet.

[Pont406]

I took my 69 to get some hp numbers at the wheels. All stock 69c10 truck with almost stock pontiac 400. Best pull 310 hp at the wheels. After heat soak numbers droped to 302hp. After secondary rods change got it back to 304hp. So it's basicly 304 hp at the wheels. 304hp at 5200 rpm and 342 max torque. All on 89 octane gas. We tryed 91 and no difference. I need to get a power trax locker next and maybe some passes.
