Cylinder head discussion 340 with stock above deck pistons

I am guessing it's been a very long time since you have raced a clutch car. The days of flooring it and dropping the clutch with a 3600 lbs pressure plate are long gone unless you really like destroying driveline parts. It's all about clutch management now.

I had a 3400 pound pressure plate back in the 1970’s that I raced on both the streets and drag strip. Don’t say it can’t be done.
