well thanks, but the problem is i'm never really happy. I will go another season with pump gas with a few add ons. maybe I can lose a couple more tenths maybe not, but I want to see what it will do on pump gas first. end of next season i'll be looking at a race gas combo and that is the point of this thread. looks like i'll stay with the 4" with 13-13.5:1 and light parts. i'll have the heads looked at buy a mopar professional. can ya suggest a good mopar cylinder head shop?



I would suggest Jerry Arnold here in Kalamazoo. He is a former national record holder in comp, and is mighty handy( and reasonable) porting heads, and setting them up, etc.
I know he did Al's heads( the yellow Duster that has the same heads as yours and has run 9.60's)
Definitely would be a guy I would highly recommend.
