when the mopar 292-509 cam i was running in my 440 powered 65 Plymouth went bad all i did was change the cam to the comp 305-525 solid lifter and reused my Indy 1.6 roller rockers.my et went from 12.05/12.10 to 11.84 in the 1/4, i think i even hit a 11.70 once. now i might of not went much faster but the car was a lot more fun on the street and sounded wicked.
