WHICH CAM?

Post by STINGER477 »

I got a sbc 350/ 2-1 rotator w/ 3-blade R-series 78"
Should I go with a cam that makes torque/hp. down low or mid to upper rpm range?

Well you want to go with a cam that will bring your torque in low but carry it across the RPM range and it will suit you best. You can probably get a cam that will come in 2000-2800 and peak out around 4800-5000. Call Waterthunder or Mike Felber and they can get you the best grind for your components you currently run that will be key. Good luck and keep us posted.

Comp cams 12-236-3 will be a great choice for your app. It comes in under 1300 and peaks at 5500. With a lift of .462 int and .477 exh , with a lobe seperation of 112 deg , you don't have to do much else to get it in the motor. If you want more lift get a set of 1.52 or 1.56 rockers, the down sid is if you do that you should do a lil trickin to your heads.
