Hello, I have a LS3 ENGINE in my 2000 Camaro, I'm thinking about Scorpian roller rockers instead of Comp Cams trunion upgrade kit for stock rockers.
My question; The motor is bored & stroked to 418 C.I. what ratio will fit w/o issue 1.8 or 1.7??

Thanks in Advance.

Stick with the Comp upgrade. It's all you will need.

Sorry I just realized 575 HP Flywheel / 508 TRQ But it's in serious need of a real tune. The engine builder didn't tune it 100% in his defense the car was shipped to him with no front nose and wasn't registered so he didn't get to complete a real world tune on the road(shift points on A4 need to be syncronized . Working on getting one with Mike Norris Motorsports.

They dont have the greatest track record. In fact about the only two that do are jesel and crower and they will set you back $800+

Stock with the upgrade are great. They are light strong and economical

Yes that seems the general consensus. I'm just not equipped to swap out the Trunions and press in the kit into rockers. I thought it would be easier, to buy caged needle roller rockers.

Check with Richard at WCCH for his CHE "bushed" GM rockers. They would work well with that lift.

Do they offer LSs1/1.72 intake rockers too?

Summit sells a tool that allows you to push the factory trunions out and press the new ones in using only a bench vise. It takes about an hour to do (excluding removing and reinstalling them in the car).
