I was just wondering if you guys thought it would run 12's I was thinking maybe but now not so sure. Prob just keep stuff I got & buy a better cam
Those take out cams are old Crane cams out of boat engines for the most part. They don't normally have enough RPM range for the gear and converter you have.

Consider a Lunati Voodoo camshaft, steel billet with the standard iron distributor gear (you have to order it that way) or use the regular steel core and a Comp composite distributor gear. The old number is 60212. The new number is 20110712. You could go one step bigger with the 20110713, but you don't really have the compression or the intake (you need an RPM series or similar to make it work right).

With that converter, you could run a Comp 11-456-9 (the -9 makes it steel, and a custom), they say it is for a boat, but if you put it in at 108, it has a real broad power band. It does not have as much lift as the Lunati. I run the Comp steel cores with their composite distributor gear, they work great.
