Why not keep your stockers and do the comp cam trunnion upgrade? As far as pushrods, the only to know for sure is to measure.

Yea I'd pass in the higher ratio rockers as the benefit of slightly higher lift isn't worth valavtrain stability, the higher ratio is for ls7s and people who are too lazy to swap the stock cam...the cam itself will give you what you want

As far as roller tip rockers I wouldn't go that route either unless you are going to take time to make sure your wipe pattern is right on...do yourself a favor and do the the noon upgrade like the other guy said and you can spin it as high as your heart content...good luck bro and enjoy that cam!

Money would be MUCH better spent porting the 243s than on rocker ratio.

Yea +1 on that...hard parts are where the power is at...if a part is easy to install (ie rocker arms, plug in tuner, air filter) it usually doesn't add much power...heads, cam, exhaust, cubes, blowers is where it's at...

Ok wow thanks for all the reply's guys ok so might be a dumb question ive been out the game for a while but whats this trunnion upgrade

IMO, go with the trunion rocker upgrade.
It up grades the bearings and pivot shafts on the factory rockers.

The trunion upgrade is when you replace the uncaged needle bearing with a caged version.. So they don't spill out into your engine like the stock ones sometimes do...

Summit, comp cams both make them... Among others

Comp Trunion upgrade. Stock rockers are the best for LS1. Keep them.

Ok so lets say with some 243's the cam I got and a 125 shot what kind of hp/tq numbers you guys think im looking at

Roughly 500, very rough too.

All motor probably 380-390rwhp with good tune if you have supporting bolt ons and then obviously around 500rwhp with the 150 shot, make sure you have an aftermarket fuel pump or booster bc I've always been told its a rule of thumb not to go above a 125 shot on the stock pump, you especially since you will have a cam and good flowing heads, your tuner will be able to tell you the biggest shot you can handle with stock pump after dynoing all motor

Oh yeah I got a racetronix with the hot wire kit and full exhaust with a slp lm1 I just got me some 42lb green tops and im looking to get an after market fuel rail I was thinking of some d585 coils but I think the stockers should be fine for now and for now im just gona send my Ecu to frost to get a tune
