I was ask a question the other day....what is the maximum cam lift you can use with 1.5 stamped steel rockers? Any idea?
Sorry for the typo,272/284 duration.
Not sure of the brand, they look like more of a dampener spring on the inside, they were on the heads when I bought them, my machinist thinks they are aftermarket, not stock 340 springs, he checked em, as well as checking seat pressure. They may be direct replacement for the factory springs. Said they would go as high as .550 lift. But that would be pushing it.What valve springs? I ran a .509 DC cam with stock rockers and beat the hell out of it for several years before it poked a pushrod through one. If the springs aren't outrageous you should be golden.
