As stated above trans are rate in torque capacity. Search the web and see how GM rates their auto trans and Tremec rates their manual trans.

Don't have the nitrous come in to low an RPM.

If in fact these heads flow the rumored 300 cfm. Then IMO someone replacing a stock head without doing any other changes will not be happy.

Paul,
Do you believe that some over balance is not a problem?

If so, and he has room to dish his piston. Do you think he would be OK without re-balancing?

Matt,
Have you talked to Ed Page screen name RAIV-Z here on PY. He has a twin turbo 535 ci with DCI RA V heads. I believe this past year he had John Marcella do some work on them.

In this case I believe they were just random checks done after class was run. From what I understand the Camaro had a problem with his pistons and the other 3 passed inspection.

I used 3800 pounds. Do you know what your car weighs with you in it?

Are you racing with the headers open or closed?
