Missed on this combo?
Well, 540 is not that hard.
Anyhow... YR I'd be worried about 3 things with that Ultradyne.
1 valve to piston clearance. I have to check my notebook but I think I have .110/.098 now.
2. At 11.4 to 1, do I have enough compression?
And 3.....might my cylinder pressure be way low?
Waiting for a flywheel to check cranking compression. I'm really interested to see where that is........hate to do it cold, but I guess I'll get a good idea where I'm at.
