Don,
isn't that polaris "victory" twin built to this free rev
configuration?
how about the available valve to piston clearence in the Max
motor? J.G. at PCW cut the domes back and retarted the intake cams on Tylers
1260 to keep the valves out of the pistons using the stock cams. don't sound
like there's very much to work with to start. an interesting sideline is
the fact that you can put .375 lift/257* dur. cams in the stock motor with
out hitting the stock pistons. the 1260 pistons are said to boost the
compression to 11:1, the extra material might all be on top?
