When I bumped to 20 sounded really good seem to have the power no hesitation. But the dreaded hard start. I purchased Dist springs from summitt today. See how that goes. Sounds like i went with the wrong cam I wasn't sure at the time. Did have some good positive things. I have a hard time remembering things lucky it ran i guess. I know my oil pressure was low like 40 hot highway 30lbs idle 10-15 According to what people are saying the shop i had put the cam and bearings in probably had a bearing not right over the hole in the block. OK will wait for the springs see how it goes will let you know Kevin
