Cam Question

[motoheada1]

Hey There

I'm currently putting a combo together that is pretty much a "clean out the shop build. I have a cam, but its got me a little worried and i would like everyone's opinion. First some info on the combo.

1966 Chevy II 3000lbs +-
10.5x28 slick or a radial of similar size
5.14 gear and a Glide with a 5K converter and Brake

SBC 363ci 4.030 x 3 9/16
13.8 CR
6.0" steel rod
AFR 1103 heads
Ported super Victor intake
HP 950 carb

Ok now the problem. the cam I have laying around is a Crane TR260/4167-2-4. Its actually listed as a circle track cam. Besides that fact, it seems like it may be a little small for the combo.

specs....260/270 @ .050 on a 104LC .625 lift with a 1.5 rocker

What makes it a "circle track" cam, and does that automatically make it bad for drag racing?

Any help or other cam recommendations would be much appreciated.

Good afternoon to all,
What usually made a Circle track cam was it usually made more torque through the mid-range RPM and kinda petered out at the upper RPM levels. I'd say stick it in , degree it, put some 1.6 rockers on the intake side and check your piston to valve clearance.
Then go have some fun, check your finish line RPM and gear the rear accordingly.
