340 Roller Cam/Lifter Issues.

don't think much of comp cam rep's , did an old school hotrod p/u for a friend . he wanted a blown chevy in it , so the engine builder called comp about cams , mind you this is just a hotrod driver , not a racer . cam lube seperation was based at 109 with a couple of degree lead , overlapping int/exh lubes , on a blown street motor ?! should have been 114 to 116 straight up with no overlapping for that tight full hooded sleeper machine , the thing ran hot until you were on the freeway . have talk with a few different cam grinders now , and one said that tight of centers , some lube overlap just sends or blows fuel out into the exhaust . not what a blown street motor needs .
