Camshaft choice/lifter kits: How easy is this JOB? I'm losing alot of oil pressure latley and I'm not sure if its my oil pump or if its a combination of worn cam lobes and lifters. The engine has 88,000 miles and it was a 350 crate replacement(not by me!) What kind of tear down time would I be looking at? Can I leave the engine in the truck while this is perfromed? Whats the best combo for a kit-- I think I'm going with JEGS as my purchase source since Summitracing seems to be a bit lack luster in the customer service department.(hate to say it but I got the run around once for something comepletely different with them.) the truck is almost completely on the road but I do swap out the 33" road treads( BALD BFG's!) for the 33" offroad meats. what information do I need to order the right Cam/lifter set...do I need to have the block milled at all? I'm totally lost when It comes to digging anywhere past the Carbs! Please Help! Blazing in Maine! "You tried your best and you failed miserably.The lesson is, never try"
