Just Purchased Virgin 340 Short - What to do with Pistons
No offense but if you are assembling it yourself, then you should be able to figure out compression ratio. It's a math equation based on measurements of your motor and gaskets. I'm in same situation as you. You'll get satisfaction doing it yourself.
Google Wallace compression calculator.
Give it a go and post your results.
Someone here will double chk results.
Hope I didnt sound like a dick.
