49 cc's about right?

[theman1990]

About to get our 1978 large log 250 head milled and I think 49cc's should be about right for 9.0:1 compression with a .044 compressed composite gasket on a stock 1965 200 c.i. engine? Block has never been decked and pistons are stock.... Any thoughts?

that sounds close, i would recommend running the math a couple of times before you have teh head milled though just to be sure.

Here's a link to a popular compression calculator

see if you get close to your target static compression ratio...

have fun
