My neighbor is building up his 350 for his 70 Camaro.Its a true 12 to 1 compression,200cc Dart heads,RPM intake,830 carb,1 5/8ths hooker super comp headers.He is using one of Iskys circle track cams with the 106 LSA(244 duration,484 lift)Im just curious,how well do any of you out there think this will perform?They also make a grind with 105 LSA.That cam must sound INSANE at idle,

My last cam had 251 degrees @ .050 and 106 degree LSA....Big block Chevy.
I really liked the power it made and it sounded really mean rumbling around town! :)

Cam in my circle track car has duration 0f 260 @50, lift .625. Idle sounds awsome. Starts to smooth out around 3500 rpm. NOT a street motor. It needs to be run at least 4000 rpm. Makes 3/4 of a mile per gallon.

Usually circle track cams are easier on part vs. drag racing cams.

I've ran more than a few Crower circle track cams in my street/strip SBC's in an effort for my valve springs to live more than a season of bracket racing and street driving.

I think they work well for street strip action. Also I would run something a tad bigger with that compression. Call isky up and see what they suggest.
I used the 242/242 @.050, 270dur @.020, 530/530" lift, on a 108lsa before. That's an off the shelf grind that works. But I wouldn't use it for you compression.

The only difference in cams are the specs in which they are ground and material they are made of. Circle track cams are ground for the specific needs of circle track racing and even those vary from track to track. When I ran circle track our cams (and engines) where designed to build torque coming out of the corner and be at almost peak horsepower just before the end of the straight away. We had two different motors, one was for the short track we ran and the other was for the large track.
