sbc camshaft question
I know everyone loves talking about cams, so heres a question. I'm looking at running the comp extreme solid 268, flat top 30 over 350. stock intake n quadrajet, 441 heads...I was wondering if anyone here has ran one, and what kinda vacuum did it pull? I was also wondering about a cam that comp hasnt replied to me about. cca-12-321-4. In the summit online catolog, it says it has a power range from 1500-6500, 270-280 duration, 470-460 lift. the rpm range just sounds to good to be true for me! its exactly what i'm looking for, but i'm hoping to pull about 17" vacuum. comp cam help says to run an ext268, but that was the hydraulic lifter. They said if not they could regrind an ext274 to pull the vacuum. They just havent gotten back with me about the 268 solid hyd., or the special 12-321-4 specs. I'm really looking for the edge with these few cams here. Thanks ahead for all info!
