Really thought many disagree with me but myself and a few locals keep going back to a huge head on smaller motors and they just down right fly ! I've now did this 2 times 548 with dart 410's and 468 with dart 355's, a good friend of mine put dart 360's on his 496 all 3 motors really ran good better then anything around here with the same size motor and smaller head.

That being said,the carb and cam have to work together also.
Did you guys have to try different carbs and cams with the low compression,big heads and big cubes to make things work together :?: Was there a fine point(small window) for the carb and cam :?:
