Due to a problem with my P90 head, its getting fixed due to a bad gas incident a month ago resulting in a bent valve and leaving #5 with 0 psi on a compression test. While its there I am having the cam go through a regrind to what he thinks will be a good setup for what im looking for (mild, good street setup). He said it will give a lumpy idle, and strong pull all the way up to 7000 rpm. He is a local builder and this is a spec he uses on carb'd engines. Any thoughts? 280 duration .480 lift 106 lobe center Valve Timing: Intake: .010 lift opens at 31* BTDC closes 31* ATDC (62* overlap) Exhaust: .010 lift closes at 69* ATDC / opens 69* BBDC
