rocker arms Stud or Shaft, Crane or Comp
 

in the process of finishing my 540 SCI builds. Now looking into rocker arms type and styles. I have Comp Cams Ultra Pro rockers and several sets of Crane golds. Which ones are best for Hyd. roller .60 lift? Also when is a good time to go to shaft mounts like Jesel? Going to spin engines to 5800 RPM.

Skip both of the brands you listed. Crane Golds are not as good as they used to be. Buy the Scorpion Endurance Marine Lifters. These are the same as what are used in all Merc Blue Engines.

go with T&D shaft rockers if you want the ultimate in reliability

bingo:evilb:

thanks, who sells them? I've been looking around

(775) 884-2292 T&D Machine products. Call them directly, they are great to deal with and will be able to sell u a shaft rocker system thats built just for your brand of heads

P.s.- go with the 1 piece intake stand systems instead of the individual stands, and once you set them all up get the exhaust stands welded to the intake stands. Then you will have an extremely stable and solid valvetrain. :drink:

T&D is the way to go , just not for the faint of wallet . $1363.00 for a set to fit my brodix head's and 3 weeks for delivery .:eek:

I hear ya, i just purchased 2 new sets of the steel shaft rockers with spring oilers, 1950 per set but man are they some nice pieces!!!!

I will never buy anything but the best of the best for my valvetrain components, when cheaper **** breaks it costs much much more in the long run to fix what gets destroyed when low end parts break.
