Want quieter rockers!
SBC 327 w. dart iron heads, street engine
I have a .590 lift solid roller cam with comp pro magnum rockers, they sound like a big sewing machine shssh, shshs, shssh etc. I dont wanna hear that drone.
Can I use non-roller long-slot rockers or do I have too much lift?
I use 1.25" diameter beehive springs ~350-380 lbs open pressure.
Your going to have the sewing machine effect with a solid cam and lifter setup. Sounds like you should have went with a hyd cam and lifters. IMHO
Set the valve lash cold at .014" in .016" ex.
Change the rockers to Scorpion.
The valvetrain will be noticiably quieter.
