OOOPS!!!!!Must have missed that pesky zero.You are absolutely right of course...
That invaladates my math.
Total cid is now 326 and compression 9.44:1.
Thanks for catching my math mistake BJR.I am prone to that after 11:30 p.m ... :)
Just out of interest,with a max overbore of .060,cubes come up to 330, and compression to 9.5:1.I probably wouldn't bother boring this much as I think the cylinder walls might loose too much integrity and tend to go out of round at higher rpms.Opinions??Maybe this wont happen unless the bore is crazy bored out to 4.00??What is the max overbore for a teen with the cylinder still retaining it's structural integrity?
