Intended use is strictly street rod.
With the old motor running the TRW's I was pushing about 11.5:1 on leaded premium and shifting around 6K using 6500 as redline. The cam was really strong above 4500. I ran this combo with both the 3.55 and 3.91 gears and the A833 4 speed and it was a screamer. I would simply re-do the motor to the previous build specs but I'm afraid the modern ethanol crap at 93 octane won't tolerate it. BTW, I was running 32 degrees total advance (mechanical only) with quick advance kit and never noticed any detonation, nor do the piston domes or combustion chambers show any signs. Was I lucky? Maybe. Just not sure if I would be so lucky with the pump gas they are selling today.
