Danny is right. You must have some way to stop the lifter from rotating in a roller lifter set up. If the lifter turns it can damage the cam, lifter, lifter bore(which may require a new block) and further if the bearing does come apart.

 

I choose to use the lifter trays vs tie bar style. The tie bar adds weight to the valve train and is one more thing to go wrong at 7000 rpm. However i use the ls2 trays not the one that came on our motors. The ls2 trays allow oil to drain out of the them...chasing the extra .75 hp. I'm not even sure if you can get the old lq9 one anymore. DO NOT START THE MOTOR WITH OUT THE LIFTER BEING GUIDED. it can gall the cam and roller in no time.

 

I don't think a large lift cam can pull the lifter out of the tray though. The base circle of the cam is what would do that, and i think the larger duration/lift cams have a larger base circle so this would be even better.

Krambo, Brad, please let me know what you think I just wanna be sure this is done rite!

 

 

LOL it's not about what people think about the lifter trays, it's about what is REQUIRED in order to properly run your lifters!

I know a lot of LS guys drill out holes in their lifter trays for oil drain back at higher RPMs too.

This is not suppose to be a "see your wrong" type of thing. I used the sources available to me to make the best, most accurate decision on the trays after I thought there could be issues (after talking to Brian). so its done rite, but I can expect all the shit to be tossed my way because I made a mistake. With that being said thanks to all that contributed to this. :cheers:

Nope. :shakehead:

 

He's also been right sizing up a person's "heterosexual weakness." :jester: :jester: :jester:
