fooling my small block
:-D
Hey, valiantmike, does that cam rock?
If you are speaking of the Comp XE268, lemme tell you, it is an awesome cam for a 318. I have lightly machined stock 318 heads and valves, .030 over block, stock compression bottom end. It is perfectly drivable with the stock converter. Not too sluggish out of the hole, even with the soon to be replaced 2.76 gearing. With headers, I have given up nothing in low end torque to the 260H cam, with similar to 340 specs, if anything, gained. I havent taken it over 3,000 RPM yet, but I feel that it has even more reserved for the top end. As for the idle, with the headers, it had a pretty good lope to it and its completely noticible( rumpity, rumpity, rumpity, rump). It sounds down right mean. I am stoked with the combo. It is a good cam in other combos too. One of the best cams made.
As far as idle quality and low end with big chambered heads with low veloscity, it will probably be different than stock heads.
