hi a friend sell me a Comp Cams, he said its only for 1/4 mile and the engine cant use in the street but i dont know much about that, here is the specification of the cam shaft :gross valve lift .490, duration at .050 intake 230 exhaust 236, lobe lift intake .3270 exhaust .3270, lobe separation 110.0 its hydraulic... please i need to know if i can use in the street?

 

yeah you should be fine on the street

 

I am running a LOT bigger than that.

 

Might want to mention what engine you're putting it in.

 

its a chevrolet 350 from my camaro 1979

 

how can knows the RPM range?

 

help me urgent

 

Why dont you look for a similar one on the comp cams website (or the exact one) to get an idea of the rpm range.

 

Comp Cams hydraulic flat tappet (not roller lifter) cam for SBC:

Xtreme Energy P/N 12-246-3 Grind # XE274H has these exact specs.
It is described as "Very strong mid range, torque and throttle response." It recommends a torque converter with a stall of 2200+ rpm. RPM operating range is 1800 to 6000.

I might not use it in a completely stock automatic with 2.73 gears, but if I had the 2200 or higher stall speed, a free flowing cat-back exhaust and maybe headers, it would probably work fairly well. You need to make sure you have the correct valve springs and push rods to go with it.

Does that information help, reivax?
