after repairing it, I put in a s10 that got sold before I finished it and he went 9.75 in it with a 5500 stall 4.10 gear combination. It worked well. 347 c.i 11.8 compression and ported 5.3 heads

not quite 20. Close though, I never got to try it out as we spun rod bearings on dyno.

Geoff really does know **** when it comes to manipulating some valve timing. The cam before this was great...but he and I talked...I told him I wanted more average power per gear change. In a nutshell that means we needed to flatten the curve for more average power under the curve....especially in a T56 car !! And IMO, he delivered.
Auto can get away with a peakier curve...but that seems to slow the manual car down.
It's not apples to apples...but I technically lost "peak power" but made more per gear change. Thus, the car gained mph.
Thanks...

Sounds like an awesome build....amazing how well these little LS's run with a sorted combo.

10-4 on the stock rocker deal....Speedtiger (iirc) and i had a conversation about it a few years ago here on the board.
In my personal opinion my setup in better for many reasons....that's why i didn't go that route. Didn't feel there is any performance gain over what I'm running...not to mention triple the price and complexity.
I'm a big fan of K.I.S.S.
But a back to back test would be a very cool idea.
