Pat,

I am still learning. Your best bet is to talk to Dan or Mark on the spec's, and for any advice as well. I know Dan starts with the heads to determine how much work was done if any to them beforehand. This will determine the compression ratio target, and in the case of mine was 9.5:1 which is close to max. He did use a modified cam very close to the 068 specs, and custom pistons to increase comp as I remember within P/S rules.

He also does a desktop dyno build and then trys to beat it. He gave me a lot of options to choose from. All I know is his HO cars, and Mark's TA prove the results at the track, and they look great doing it.

Chris and I recently saw Mark's 70 RA IV TA, and it was stunning!
