If you get a negative as your compression result, then yeah you've put the pistons through the cylinder head. (in reply to Sldwys11687) Post #: 81

I've heard of people going .02 out the block, so .007 shouldn't be a problem. You would definitely want to clay it though, to make sure the valves won't hit the tops of the pistons. I can't remember what piston-to-valve clearance needs to be. I wanna say .040"? (in reply to Sldwys11687) Post #: 83

I got a CR of 11.91:1 a Rod/Stroke ratio of 1.73 but then i got the piston-to-deck height of -.007. (in reply to Kedawei) Post #: 84

RE: What engine to boost? - 5/2/2007 7:47:15 AM    Sldwys11687   Posts: 23 Joined: 4/11/2007 Status: offline Quick question on rod to stroke length. Would it be better to go with a stroke length of 1.73:1 like in the b16 or 1.58 like the b18, cuz i read that the higher the stroke is to 2 the better for high reving engines, like formula cars meaning that it stays in the power band longer while the b18's lower stroke helps on torque.
