Re: easy way to figure cam lift on sbc in truck? worried changing heads
What are the numbers on the heads? Your going to shoot for 36 degrees total timing @3k rpm with vac advanced disconnected.Valve float isnt noisey it will just feel like a bog and is unlikely to occur until around 5k rpm even with stock springs. Pull your valve covers and see if you have any loose rockers. The absolute most common reason for loose rockers or lifter noise at this point is a wiped out cam. If the cam wasnt properly broke in or if oil with the proper amount of zinc hasnt been used theres a good chance you have a cam problem.
