Rocker arm?

What rocker arm would be best for for a .900 lift cam and 950# open spring pressure in an iron head, i have a jomar girdle already, i was looking at a crower steel roller rocker arm max rpm maybe 7500

The best stud mounted rocker would be the Crower S.S.

Thanks. If a shaft mount system was in the budget for it what would you recommend ? Jessel?

Nothing wrong with T&D in my experience. Crower is THE best SS rocker out there.

Not Jesel. T&D would be my only choice.

Thanks

Harland  Sharp for stud mounted, or jessel, or WW for shafts

I seen Harlan Sharp has new HD rocker arm for big lifts and high spring pressure

they have for quite a while. work great , and are lite compared to SS stuff @ any rpm

Price seemed reasonable to , will have to look into them some more

Much of the Crower S.S. wt. is in the big ass shaft......which does not rotate.

As far as those which are currently in production and readily available, the Crower stud rockers--both aluminum and steel--have the best design geometry for their originally-intended cylinder head applications.

Given your noted lift and presumed spring pressures, I'd recommend the Crower steel.

Thanks for the replies, we'll be using Pac 1248 springs.One more question, builder said bushed roller lifters, any suggestions on which ones to use thanks
