Smile Re: 1955 Chevrolet Q/SA Build

Currently waiting on some parts to update the engine. As I have explained in the engine build up since the 55 265 is limited to flat top pistons there is not much valve to piston clearance. Cams with more than about 230 degrees duration do not have enough clearance. So in talks with a couple of engine builders with knowledge of this situation I have been told that heads with more angle mill to them will give you a little more clearance. Hope to to get those heads in the next month or so and will test them, and a new cam . Also waiting on a #2 carb from Deano with some different jetting. First one really perked up the engine. Thanks for the interest. Lyn
