Looking good. This thing is going to make some steam soon enough. But, go pay those bills and enjoy the scenery.

Nice to see they are waking up to using properly designed bearings with inner and outer races. I highlighted that problem on LS1tech years ago - just as the bronze bushings came on scene to compensate for the Comp trunnion upgrade eating through the non-hardened shafts.

Can you explain the rocker setup?
I don't know if I've ever seen this.
Its basically a rocker shaft setup to distribute load over several fastener points to reduce deflection at high RPM with upgraded bearings and retainers so it doesn't puke rollers into the bottom end.

I bought the brass bushed trunions for gen 1 of this motor but I was never really in love with the idea for a "street driven" car. I think this will be a big upgrade for where I need the power band to be. Now I just need more cam, eventually.....

Those are for ‘spinning it’ baby :)

Stock rockers will cover 7500 all day and an occasional 8k moment with 400lbs over the nose. These rocker shaft setups are ready 600-700psi over the nose - meaning a crap ton of rpms and boost. 8500+ and 40-50psi on the back side of valve.

It ain’t a junkyard LS build anymore 😂

Hopefully, with no sarcasm intended. I want see how long it takes you to swap to a GT55. And I think you know someone that will be interested in the S488 ;)
Lol, I was thinking 96/113. Something T6 that bolts in.

Either way I should have everything more or less matched up, other than the cam, for what I want to do. I finally made a plan and had a goal, then stopped changing mid build like a retard.

Stop the ‘changing of the plan’.
I was kidding about the turbo. Big power is way easier than going fast.
If you can get it to turn a 1000hp time slip, then you’ll know the next step. I’m struggling with what I have and that about 4 sizes smaller if turbo.
