I own a 1966 chevy c-10 truck its got a 350 with 9:1 compression and it has a holly intake 1000-6500 rpm and a 660 center squirter carb sportsman two heads also i have a turbo350 with a 2500 stall, and i the rear i have a 12bolt with 3:73 and a 29inch tall tire everything else is stock what do ya'll think a good cam would be for hp and torque not just towing it will never be towing anything.

if you want drive-in restaurant "rump-rump", use something like this from Crane. It's ground on 106 degree centers, so it'll sound nasty...

If you prefer a smoother idle, maybe something like this ground on a 110 degree center would work better for you....

Hey tech, wouldn't the lobe seperation dictate the idle quality? I always thought that 112-114 were factory lobe seperations and that a noticeable idle develops with around 110 and 106 could get down right ugly sounding. Of course this could depend on the engine size and make. Any thoughts?

I would suggest not going too radical, but go as radical on the cam grind that is acceptable with your compression ratio. That's what I would do anyway.

Yep 53, you're right on the money. I guess it's all relative. A 112-114 center is gonna be dead smooth 'cause that's what 99.9% of new car buyers want. It's the other 0.1% of us knuckleheads that want a little sound with our cams. A cam ground on 110 will not be as dead smooth as a factory cam, but it won't be as raspy as a cam ground on 106 either. My buddy had his cam ground on 104 centers and it sounded reaaaaaallllly good. He kept the duration within limits for his 9:1 compression just like I did when I picked those 2 cams for Speed Freak. With about the same combination in a '59 Stude pickup and a ladder bar rear with pinion snubber, he went 11.84 at Firebird, so the cam worked pretty well. I sold him a set of Goodyear slicks and a 4.30 third member for his 9", so that didn't hurt his combo either

what kind of track did he run at? eighth or quarter ..... just wondering, I hope you say quarter....

Firebird is a world-class 1/4 mile dragstrip facility.

If the truck went that fast.....and the motor was pretty close to the same as mine, that would mean that alot of the work was done on the suspension? I never figured that an engine anything like the one that I have would pull those kind of numbers. That is kind of refreshing
