OK; stating "a .490 lift cam" tells us almost nothing what-so-ever about the cam's performance parameters.

Can you provide more information? Duration? LSA? Valve opening/closing events?

Also, what would be the compression ratio with a stock sized combustion chamber?

Thanks!

Maybe it's just the shadow, but this one piston looks like there's at least .050 clearance between it and the cylinder wall...
