LSA conversion on an LS3 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Samspeed · 01-11-2022, 08:05 PM

I’m going to use an LS9 powermax cam and was wondering if anyone had used it.
It recommends a pac 1218 spring but the cam is .600” lift, will that work?
And can I use the stock LS3 pushrods?
2010 2ss 6 speed
Mods will be LSA Supercharger with a 2.75” pulley, LS9 powermax cam, CAI, LT Headers any help would be appreciated!!

I do not have any experience with that particular camshaft. I'd feel comfortable using their recommended spring, PAC 1218, as well as re-using the stock pushrods. As long as you are sticking with a single spring, stock pushrods should be just fine.

As long as the base circle of the camshaft is the same as the stock cam, then the pushrod length should not change. The base circle of the cam is the smallest measurement you can get on the cam lobe.

But instead of guessing you should spend $30 and get the tool.
