Say something like the Lunati .600/.600 VooDoo or the Comp XR292R. Will the Crane iron rockers handle the spring pressure of a street roller? The Comp recomended spring has an open load of 456 pounds. Thanks! Michael Michael

But your talking about 40% more pressure overall compared to a solid flat cam.

Michael Michael I have those two EXACT cams and am deciding which one to run in my 511 RB. (Thinking VooDoo! Got it off Ebay AFTER I had the XR292...) I have Stealth heads with Isky 9205 springs (aprox 190# seat and maybe 475# open), and I sent some original MaxWedge rockers to RAS and had them bronze bushed and fitted to my shafts. Well worth the investment for durability and simplicity! RB

Plus shipping to California of course. Nicely bushed with re-routed oiling and internally grooved. I would rather have these than budget full rollers or higher priced roller-tipped ones that would gall to the shafts under the pressure... RB

My set has been street driven and raced on several cars and are still like new. Mine were also changed to 1.6 when they were done. It was a lot of money but for long term service I think they will be hard to beat. Getting old just means you were smarter than some and luckier than others.

I provided my own Crane shafts and Crower adjusters, so I guess I could have bought some bushed PRW roller tips or maybe some Crane golds new for what I have in these, but not like Harland Sharps or anything like that. Prolly have less than $300 in the whole deal but I feel good about them for the street. I had two sets of Iskys done previously with RAS supplying the new adjusters, shafts and hold downs, and I think it was $400+ per setup, but NICE stuff with zero problems. RB

Quality is never cheap, you get what you pay for, if your lucky AND don't pi$$ of the owners Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

I'm thinking of stepping up my camshaft a bit for the rebuild I have in store.. Can't decide if I should bush them (RAS) or sell and buy HS.... Michael

I`m going on 6+ years w/LOTS of street miles and a few hundred passes and all is well. I don`t skimp on my car......maybe that`s why it doesn`t break and has never let me down or left me stranded.

But they were "relieved" for spring clearance and I left a sharp cut instead of blending it. I ran Harland Sharps on a W-2 360 for many years with no problems. A few tip rollers may have started to get worn. But the only ones I recall seeing broken were ones cut for spring clearance.
