340 r.i.p.

revving 340..looks like it was revving when it let loose. Seriously, a 360 can be built with better street manners than a 340, longer throw means more torque. Same heads mean same HP potential. Yeah, you could sleeve it for 40-90 a hole, then scrounge a steel crank (cast 340 is short run piece) damper and rods, etc.. Just get a roller 360. Youll be money ahead. You could even put the 340 pie tin on it and none would be the wiser except you.
