I have a 93 M6 Z with a 355 with stock rods and crank with forged pistons and ported heads. I believe the cr is about stock. My question is how many pounds can I run and be safe? The car is just a weekend and track car. I would like to stay pump gas 93...

Thanks

With good pistons and a good tune you might get away with 9 pounds or so
