Thread: Screw in studs in 461 camel humps

Tweet

For many years we used MR Gasket bolts . Long before ARP was around . From head bolts SPS rod bolts screw in studs and engine bolt kits . They use grade 8 bolts . And the screw in stud are 7/16-14 at the mounting . 3/8 at the rocker ball . I am installing a set in a pair of 1969 #186 fuellys . And have used them before with a 525 lift cam . They are all that you will need and only $30.00 bucks . Just think of all the Vortec heads running on SB Chevys with the pressed in 3/8s studs ?

The reason why I want to get 7/16" studs is because I have a nice set of Crower full roller rockers I want to use, they are 1.65 ratio. I want to pair them up with a smaller cam on a 400 small block in order to make BIG lowend power. It will be done making power at 5500rpm but it should make close to 500lbs of torque at very low rpm. I could use 3/8" studs but all I have for that is some 1.52 comp roller tip rockers.
