Engine tech inc Rockers
Hey guys, has anyone had any luck with the engine tech factory replacement ls3 rockers? They are being sold with what looks like a comp cam trunion upgrade. I am just worried that if I buy this first my cast iron 6.2, that they will break on me. My cam I'm using has 629 max lift. Anyone know if these are made in China? If so, factory replacements are due...
thanks guys, any feedback would be appreciated greatly

What's wrong with your rocker arms? Also, if the Comp trunnion upgrade is the needle bearing type, you do not want it. The trunnions are too soft, and the needle bearing eat into the trunnion. within 5k miles

I'm upgrading from my 5.3l gen iv engine to a cast iron 6.2 I've built, I never had offset rockers. Good info on the trunion upgrade. Appreciate that.

Which heads are you using? The only offset ones are the intakes, and the part shown does not differentiate which rocker it is. Personally I would be suspicious. The valvetrain is where you do NOT want to cut corners.

I'm using ls3 heads, i know they are offset on the intake side however I'm selling my 5.3 complete therefore I dont want to use 8 of the exhaust rockers. They sell these rockers in a kit, I was just showing you an example pic of 1 they sell. I just dont want them to be like Michigan motorsports rockers from Chins. Was asking if anyone had any experience with engine tech inc rockers, that's all. Thanks for your help

A good set of roller-tipped rockers gets the job done here. Check TSP for theirs...
