340 Vs 360

Really? Crank material has a play in RPM?
Piston speed, Would you use a cast cranks for 10,000 rpm motor even a 8,000 rpm ?
Street range power suggestions?
If your building above 1.3 lbs-ft per cid your doing something right, 1:15-1.29:1 is decent average guy above 1.2:1 should be proud.
Just a quick question, was all of the above directed at me?
