602 has a cast crank with cast pistons and powder metal rods and the 604 has a steel crank with hyper pistons and the same powder metal rods.

Also, my rules say crates must run a 6600 RPM chip..........................Would a 602 hold up running up to 6600 every lap?....................Thanks,Dan

they do...........I'm not going to buy a crate because I prefer to build my own engines,,,................Just trying to get a feel for how exotic I need to be in parts selection for a 2-barrel iron head flat tappet 360 motor.............Thanks, Dan
