340 Vs 360

Like said Id take a 360 LA minus those dished pistons and I think it would run good...put a hi compression piston in it.
They will run well, get the compression up around 10-1 and a similar built 340 will have a hard time out running it.

BTW, I'll take the 440 over a 383 any day of the week. Been there, done that.
