Dan Jones has reported that those hydraulic roller lifters from Comp Cams may not work in the Cleveland because the oil hole is too high on the body and found that they couldn't maintain oil pressure because the oil hole came out the top of the bore into the beveled area. I think these lifters require a reduced base circle cam.
The Ford Motorsport Early Block Hydraulic Roller Lifters are a much better choice and don't have this oiling problem.
Garth, I've been reading as much as I can on those lifters by Comp...I was almost ready to order their entire kit (cam, roller hyd lifters, springs, pushrods, etc). Art Stephens uses the same cam and "Retro Hyd Roller Lifters from Comp Cams and has have very good luck with them in his stroker...Russ Fulps recommended those lifters, and I thought Art said Dennis A used the same kit but one level higher??? I don't think Arts lifter bores were bushed or modified. On the comp cam literature/propaganda I recall it saying their kit cams use a reduced base circle, and that the orficing inside is "NEW" so they don't pump up at higher rev...but that's if you order the entire kit with matched pieces. Then again I had one of their techs tell me that that lifter won't rev much past 5500 and that "those lifters would be a great choice for a cleveland motor since those heads don't breath". (sorry George...this might be better put in a new subject, not trying to be a hijacker)
