depends on cam base diameter. stock cam should need 7.370. i'd check w/pushrod checker.

Dude, dont risk guessing...get a push rod checker and measure them exactly. U can never be certain u have the prop length any other way - especially when u change cam or heads. They cost about $25 and its an easy thing to check once u have the rockers and springs ur using. R/

i would bet that 7.4 would be the correct length
