Not meaning to hijack the OPs original post but for me, I'm perfectly happy with my cam, it's the hydraulic roller lifters that have been problematic. Two sets, two manufacturers, both have had issues. Rather than roll the dice on yet another, I fancy the simplicity of solid lifters. They're a bit lighter too. I would have thought that with the slightly lower spring rates and less aggressive ramp, solid rollers should have an easier life on a modest hydraulic roller cam?
My car is definitely not a race car - probably less than 1500 miles a year and maybe an occasional trip up the strip for 'run what you brung' night.
I had the same sort of thing with Morel lifters, using an Erson 231/236 HR cam in a little 406" engine. Just didn't want to work right for dyno breaking and tuning.. I had solid roller lifters laying about, so put them in after jumped through my own colon for pushrods and used with the HR beehive springs PAC I believe. Per Erson used .006/.008 lash. Engine worked fine, 435HP/445ftlb torque with a basic Performer intake and 8.something:1 compression. S/F....Ken M
