You can not just hold up the lifters on that motor. The intake has to come off and you cantake the lifters out. The lifters should be fine to reuse unless you have a million miles on the truck. You should do some sort of tuning if the cam is a good increase over stock. As far as a shop up there Hardcore is in MI they are good to deal with.

No if and but about it the intake has to come off. Its not hard but you will need a tool to undo the fuel lines or pop all the injecters out. The stock lifters will be fine and another thing the grill and ever thing behind it will have to be moved to get the cam out. I didn't have to drop the oil pan ether if you are carefull it will woun't be a probelm. Iv'e done alot of cam changes before but this was my first big block it was a peace of cake started at noon had it done in plenty of time to go crusen that night.
