Not wanting to scrap the 2.25" exhaust that was installed in my Cutlass only a few months before I bought it, I'm trying to find out how much cam my 350 can use without backpressure problems. Comp's dual energy cams, according to their sales literature, "may be used in conjunction with an exhaust system that is much more restrictive than the intake system."
Would cam # 42-210-4 be a good fit? Here are the specs: 275/282 adv. duration, 219/233 @.050" duration, .476/.508 lift, 110 LSA. It's a hyd. flat tappet cam with an operating range of 1,500 to 5,800 rpm. My Cutlass has a 3.73 posi rear and a TH350 with a street/strip shift kit. I think the compression ratio is about 9.0:1. It has #5 heads. I'm going to put headers on it and either a Performer or Performer RPM intake. The car will be mostly a cruiser that sees the 1/4 mile 3-4 times a year.
Thanks in advance!
