Very nice camshaft!

Fantastic idle, not too lumpy or unstable. Sounds excellent. I have a 331 stroker motor with AFR 185cc heads, and 30lbl injectors. It will need a good tune to make it nice. Backing up is of course harder ...

    Very nice camshaft!

    Fantastic idle, not too lumpy or unstable. Sounds excellent. I have a 331 stroker motor with AFR 185cc heads, and 30lbl injectors. It will need a good tune to make it nice. Backing up is of course harder than normal, but not bad. Idle is stable, but it likes to be at 900-1,000 rpms. Take offs are good, not that much different from a stock motor/heads/camshaft. Listen to the fact that it needs at least 3.55 gears. I currently have the 3.08's (will change soon). It will take off with more power than you had, but it's not a huge difference HOWEVER, once you get above 3,000 rpms, that's when it wakes up like an adrenaline shot to the heart. Best use for the weekend warrior, perhaps a little too radical for a daily driver.
