I picked up a 1971 351 cleveland block that has been prepaired with TRW flattop pistions .040 over. crankshaft turned .010 with new bearings. The heads are 2v 1971. The heads have been redone. It appears they installed new double springs. rotating assably has been balanced. I also have a 600 CFM Holley square boar, vacume secondaries. Intake is Holley street dominator. Older intake, single plain. installing in a 1971 convertable with a standard transmission.
will most likely have headers to duals.


What would be a good camshaft grind for this motor. I would like a reasonable idle quaility, but seat of the pants exceleration is fun. Anyone build a combo with similar parts?

I think compression should be between. 9:50 to 9:90.

Thanks.

A budget 351C? That's easy! What you want is a Speed Pro(sealed power) CS1085R. I've run this cam before and it was great. Over camming a Cleveland actually just takes the fun out of it. I would also recommend swapping out the vacuum secondary carb for an edelbrock or, if you really want a holley, a double pumper. This cam will have a smooth idle. 19-20 inches of vacuum at idle. On 351 cubic inches, it will pull really strong to 4800rpm. A 2V Cleveland doesn't really want to run much past that rpm anyway with a relatively stock valvetrain, it would just be a waste of low rpm power to run more cam(thus losing the fun factor). This is also why I would HIGHLY recommend using a dual plane manifold instead of the single. It would run sooo much better in the powerband where the rest of the engine wants to make more power anyway. You'll also gain a lot of fuel economy with the dual.

Agree ^^^^^^^^^^^^^^^

Considering the cam has such critical importance to the engines performance and life, to me it makes sense to use a cam grinder who will talk with you directly- even modify the cam grind to fit your needs even better and to address the possibility of cam lobe failure with the new oils. With regards to price...the difference is nil- especially considering its cheap insurance to know exactly who is machining such a critical part for your engine. And remember, advertized lift/duration/lobe separation is just that- advertized and not the specific grind including ramp profile that is used on the cam.

That is why I highly recommend Iskenderian & Crower & Chet Herbert & Lunati...all are family owned, been grinding cams for decades, and both will even re-grind your oem cam if possible- saving you even more $.
