i called summit they won't give me the numbers he ordered. pretty gay!!

so all you put in there with the cam was new valve springs and retainers?

and new pushrods they were the better ones. not sure of length. i should have wrote it all down. we replaced the lifters too but that's because his motor had a ton of mileage and sludge. didn't think sludge was real until i took that motor apart. don't do like he did and listen to the moron at sum-it the ls1 lifters are cheaper and will work in your motor. stupid f**k told my buddy i was stupid and didn't know what i was talking about. i was so mad. and for boost felpro has a new mls gasket out and it has like some black STICKY stuff on it. suppose to seal real well.

when i talked to a guy just now he ask how i was going to adjust for the new cam. i ask what he meant, he said my rockers were no adjustable. i laughed and said um new push rods and hydrolic lifters!?!?!?. he was like oh......yeah.
