[John Lang]

Cyclecyko, Stick with the 383/w 4bbl. Check out Jim Hale's 67 cuda with a 383 4bbl!!!!! He's able to run a second under at will. That would work well in your wagon I feel! Using the 915 heads, with the smaller ex valve,1.60 could be a competitive combo. Make sure you have a well setup rear ..Good Luck, John Lang. A Mopar lover.
