All machine work and assembly on this 5.3 was done by a student for his family's Vette Cart.
It has 862 heads with 2.00 inch intake valves, CNC ported and hand blended valve job, stock crankshaft, LT rods, bored and honed 0.020 over, and more!
First of all, it’s great to have SAMTECH in the house!! Thanks for showing up. We’ve had a student or two of yours come through, one of which is a moderator here. @KCS
Please tell us more about the build in question here. A Vette cart would be a hoot!
Glad to be here! Let me know what details you're interested in and I will share!

im thinking it was 431 at the crank, as it was on a engine dyno
Obviously you are correct. I was thinking that it was a nice change to see realistic dyno numbers for a combo, If that was a youtube video dyno, that combo would be claiming 600hp, lol.
Definitely solid power for that Cart. However unlike the LS swap the world guys, I would not want it in a heavy truck having its torque peak at ~4,900.
