5.7 HEMI Vs. 408 Stroker

USCG CHARGER said

Ok.. one word of advise though.. If you are wanting to spin the car to 7K you need to look into getting a new valve train...The stock rockers will flex under that amount of rpm's ... if u are running stock 6.1 springs or pac springs will walk... The good news is that Arrington is coming out with new roller rockers that allow a duel behive style spring with custom retainers....

That's cool!! I am running single spring comp behives, titanium retainers and I already had my rockers cryo treated beacuse of that reason. The stock rockers are very dainty and thin in stock form, but I really wanted a set of roller rockers!! Jesel makes them at the tune of around $4200 and alot of machining and extra parts. I will have to give Eric Hruza or Mark BurkHardt a call. Thanks for the info!!!
