[QUOTE]Originally posted by svfreerider87: [QB] [QUOTE]Originally posted by [SHO]TIME: [qb] Okay I realize that no one here is a machinist as for roller cam intalls there is no specific break in procedures.if your installing new lifters with the cam i would definately presoak them in oil for a good day and then install them sure on initial fire up i wouldnt just start revin that bitch through the roof. just keep steady 1500 to 2000 just to get all the lifters fully pumped with oil.if your just sticking a high lift cam in a 302 without having any machining done in the heads as far as springs you can bet that your going to risk bottoming out your springs. if this happens you've got problems! I've seen this happen plenty of times and it usually results in a broken lifter and ruined cam ouch! so just measure the clearence between your spring coils at full valve open position <small>[ February 27, 2012, 12:06 AM: Message edited by: [SHO]TIME ]</small> [/qb][/QUOTE]it's to my understanding that if you pre soak the lifters they bind up, kind of like a hydrolock? correct me if i'm wrong, my machinist said if anything is going to go wrong on a fresh cam swap/engine build it's going to happen in the first 50 miles, I did what he said and drove it easy for 300 miles, with two oil changes, one at 150 miles and the final one at 300.
