I put in some crow cams 130's to go with the XP cam I have in, so I'm kind of in a quandary if I should change the cam and springs when I put the turbo on. it's not going to be a max effort build, I would probably be happy with 375.
When I put the double roller in mine, I was going to have the camfer machined to match the stock gear, and sent the double roller gear with a oem gear to a member on here, he took some measurements and the double roller gear matched the oem gear really close, so no machining was done. It's possible that at some point Rollmaster changed the specs to match the oem specs, the only real evidence I have of this is the measurements that were taken by the member on here.
