Answer
Hi Jay:

I wish I could offer more help, but the last time I was in a drag race I won it at the starting line.  By watching the forearm muscle on the flagman !!  

Truely, I've been away from drags since about 1964.  

Try writing directly to my friend Randy Cooper at:   

<< fastcash@cehighperformance.com  >>

He is an engine builder, somewhere in Arizona I think, and has a background as a mechanic in the Air Force as well. He seems to know his stuff.  

One other hint.  The Tech Line at Summit Racing is staffed with guys that are in intimate contact with the drag racing world. The phone number is 1-330-630-0240   They ask that you have all pertinent info from your car available when you call.

Maybe one of those sources will get you headed in the right direction

Good luck
