how come no one gets new lifters with their cam swaps? seems like everyone gets new springs and sometimes rods. can't the wear from the lobes of the first cam effect the new cams lobes? thought this might cause some problems? or is it b/c were runnin hydraulic lifters and the oil lubes it?

just wondering,

 

Because most are using relatively mild cams on low milage engines.Besides you have to remove the heads to change lifters and the stock roller lifters are adaquate for all but the most radical cams.That being said I'm going with Comp R lifters in my new motor,because I'm going with a .598 lift and dual valvesprings.

 

The stock lifters have a pretty good record, from reading posts on here. Kind of like the stock rockers. Many running both with high lift applications.

Comp R lifters are very picky animals that I didn't care to try and tame. Good luck with them. Seems there are more posts on here with problems than praises.

 

The only reason to go with Comp R lifter is the use of double valvesprings strong enough to collapse the stock lifters.

 

I have Comp 921s using stock lifters.

 

I upgraded my TEAs to Comp 978s and was told by Brent to go with Comp R lifters or I would collapse the stock lifters.

 

i am usind the 921's also if i read it correct. they are the new duals that fit the stock pocker and come in the kit correct. (ben)

mine are settup kinda tight too at around 1.7400 and you normaly set them around 1.7600-1.7800. but hell i dont remember it has been a fiew months since i have miked them.

i will have to agree with ben on the comp R lifter issue. i know some people that have used them and said it is a pita to get them right. and i wonder how long they will stay right. but i will also say good luck and i hope you are getting adjustable rockers.

not trying to discurrage anything but i have heard alot of issues with them like ben said.

 

I'm hoping that setting the lifter preload with an indicator dial will get them right before I install the new motor.

 

Roller lifters don't wear in on the new billet hardened cam lobes like the old flat tappet or hydraulic lifters. They don't need to be changed on a low mile cam swap unless the rollers themselves are scored or pitted.

im approaching 60k miles on my odometer. would it be wise for me to get new lifters when i do the cam swap?
