I am moving up to a.540 lift cam. I believe the stock Edelbrock springs will be ok. I am looking at max rpm around 6 grand. The springs I have now float, previous owner changed them. Open to suggestions but I want a drop in replacement.
There is more to picking springs than lift# alone, fast acting ramps(esp. those possible w/Mopar's .904 lifter)/ or rollers need much more stable springs for the same lift
than smoother profiles, sooooo what does the cam mfr. tell You to run...type/& open/closed load................................
