Sutphen 30 I think is who uses the bullet replacement cam. Will be interesting to see if he chimes in also. Those springs that are on card seem like the same ones on 741 hyd roller cam.

Which comp springs? I only did a quick search but couldn't find any comps similar to the recommended crane spring #99876.
160 closed @ 1.968 468 open @ 1.348 Seems pretty light pressures for that cam but it's what the card shows. |
These will go back pretty much 100% stock, they have 82 untouched hours now. Still have merc seals. If upgrades are going to be made these will be sold and a couple whipped 557's will replace them.

change the installed height to 1.88 or even 1.90 and those pressures will bump up, but as jd said still seems light
Just checked, bind is at 1.200, with .672 lift too close for my liking even after lash |

I'm thinking 160-170lbs range is what they are. It's been awhile since I figured them out.
|
Bill, do you have a part number? Or remember outside diameter of the springs?
