Im lookin for a hyd. roller cam for my motor. Its a 454 60 over with 10:1 srp pistons stock bottom end with arp fasteners, steel crank. Heads are stock merlin 320s. Some type of single plane manifold. Im going with the hyd. roller due to me already having the hardware. I would like to see right at 600hp if possible but retain pretty good street manners. Its going in a 70 chevelle with 3000-32000 stall 400 turbo/3:55 12 bolt posi rearend. Any ideas out there or experience? car will see nice weekend driving, a road trip 3 or so times a year, and a trip to the strip everynow and then:) .

I use an Ultradyne 233 @ .050 hyd roller in my 468 in sig.

I think a dual plane may suit you better than a single plane.

what heads are u running and whats the lift on the cam u mentioned? 11.60s in a big car like yours is pretty impressive

Steve, how's the manners of that cam?
