Quote: Assuming 4.350 bore , stock correct length rods , 7 cc for valve reliefs , .300 down to the top ring , 4.410 bore I get 10.43 ...
Using a steel shim it would have been 10.89 , so I'd have to agree with your local guru a bit on that , but since you might have to mix anyway I would have opted for the higher ratio and good quench , rolled the timing back a little on the street
cross your fingers
I can always put the steels in, I have a set on the shelf. I'm goint to start the timing at 35* and go form there.
