bryan the heads you use will dictate what weight break you get..the weight break for d/a which allows the use of canted valve heads is 7.50-8.49 lbs per cubic inch,its also the same weight break for e/a but you are only allowed to use the inline valve heads in this class.if you go 330 inches puts you at 2475 for your weight.and automatics get a 225lbs weight break.with the automatic you could build 360 inches.
