The engine that was in that Duster is 13:1 comp. 421" 274º @ .050" 108º lobe
separation installed @ 104º and ported heads.....so it's making a little more steam.

......but, OOTB Edelbrocks and 252º @ .050" on 106º lobe centers isn't
going to make power very high anyway.



edit: Maybe I should stick with 340s and 5.57 gears?
