Hi Chris:
I am involved in sports car road racing, basically funny little "furrin" cars with fairly small displacements. That and I won my last drag race by watching the flagman's forearm muscles (about 1964).
The short answer is I don't really know, but the guy that should know is Randy Cooper, e-mail him at: <<coopster62@cehighperformance.com>> He is a pro engine builder that does a lot of drag motors.
Also you can try the tech line at Summit Racing <<www.summitracing.com >> They are very helpful and their guys know their stuff - - - and I pick their brains regularly.
Good luck

During my first start in the 60's I won many solo awards and the State Championship Drags. I serve as a senior instructor for SCCA, and have taught in Mercedes AMG events at Daytona, and Dodge Viper Days at Sebring International. I have been in the thick of the competition for all of my career. At one time or another I have driven race cars at speeds nearing 195 MPH. It's quite a ride !
