so the stock ring grooves are mandated, but does that mean you cant run a thinner ring with a spacer under it?

lefty o, you can run a thinner ring, however, the ring groove spacer goes on the top side of the ring groove.

THE lowest I’ve ever heard on a SBC (8 cylinder of course) was 7 lbs/ft of rotating torque... 1 lbs/ft difference could be error.

THE lowest I’ve ever witnessed was 11-12ish rotating and I’ve been fortunate enough to have been around a lot of very sharp and competent builders/racers.

Just finished up a SBC NHRA Super Stock short block today - 4 lbs. breakaway and rotating, 15/50 break in oil on everything

Thats an amazing low number to rotate a short block. Thats a crankshaft, rods and Pistons with rings. That's only 6 in/lb
per cylinder.

My 327-275 (.390/.410 camshaft) will be about 7,400 at the finish line in decent air.
