Would be nice to be able to order these with a choice of chamber CCs, like 64CC or 55CC to be able to run flat top pistons with the bigger CC chambers OR run dish pistons with the bigger CC heads for boost. The 9 CC difference could probably be easily machined in the chambers from the raw casting. With the larger CC's when running boost we could order a spherical dish piston, with the smaller CC chambers the dish needs to be HUGE and can't be a spherical shape because of the chambers being so small.
Thanks for the information Mart! I am very curious how they will do. Will it be a mini me off the 455 port?
