I just dynoed one--PLAIN JANE 408 with dish top piston, stock main cap bolts, RPM dual plane, box stock edelbrocks--used an odd cam that was on the shelf 232 at 050 510 lift on a 112 yea I know...
on plain pump gas made 422HP and right at 500 ft lb TQ Hey ...I was happy! With tq like that it will be a fun street blaster that runs on regular gas!!




That 4" crank goes a long ways in making great power!
