Yeah, what gives with that kind of clown move huh? And no, I don't think you are picking on me, I see the humor!
Consulted with the cam grinder about using those lobes with hydraulic lifters, was told they work great in that application. This isn't willy-nilly guesswork, lot of research goes into these projects. Couldn't afford to try different hydraulic lifters. I would have liked to see what the Comp Cams Pro Magnum worked like with their short travel and the zero to .010" preload. There seems to be a real problem with oil bleeding by the short, stock, lifter bores unless they are bronze bushed and honed to tight tolerances. If you don't spend the $1000 to do that the high valve spring pressures collapse the hydraulics and the lifters rattle. We had to meet a budget on the 505 and it didn't include the lifter bores being bushed. I don't intend to build another hydraulic roller cammed engine.
In the past, the 2" spacer has done zip on the RPM and I don't own a 1". The RPM is back on the shelf and we must finish with the 505 before noon. The plan is to try a 950 on the customers Torker II and then add a 2" spacer to that just for the fun of it. We've got two pump gas street engines, a Victor headed 446/440 and a RPM headed 496/440 in the assembly room and they need to go out next week.
