Not Ranked
Hey MM,
I used the 10.300" deck height. If you have the piston made for a 0 deck, then that would add to the ratio a little bit. That .010" deck that I used, was .159 cubic inches...so if you factor that out, then the compression ratio goes up to 9.8:1. I have a BBF reference book, and even with the 10.300" it shows a .010" piston to deck clearance. I don't know if you were buying off the shelf pistons or having them made, but if you buy custom ones, you can just tell them what you want.
steelcomp: I agree with you, but he's not at that stage yet. I don't think he has all the parts for the engine buildup....so we're just trying to get a general feel for what dish and specs he needs before he orders them. When he gets the pistons he wants, then if he desires, we can calculate the compression ratio again based on his piston/cylinder clearances, volumes above the top compression ring, etc. But I think he's just wanting to know about what it would take to hit the 10:1 mark.
