Rev kits supposedly keep your hydraulic roller lifters from collapsing at higher engine speeds.AFR sells them and so does Comp Cams.Has anyone ever used one ? AFR's claims are pretty wild. Check it out.....

The rev kit that CompCams has is for solid roller lifters. Afr has one for the Hydraulic Roller Lifter. I installed a kit last summer on my 383. At first I thought the motor felt lazy in the lower rpm range. After I adjusted the timing and got a real chance to check it out,it did make a difference. Before the kit my power started to fall off at 6400rpm,after the install the motor would pull to 6800. This kit is well worth the money if anyone plans on revving their motor into the mid to upper 6000 rpm range.

FYI: Flat-tappets don't have a roller at one end.

i talked to an AFR rep about them before, and to a comp cams rep at the super chevy show......
they both told me the same thing, for a street car its not really worth it, because its such a pain to maintain it. THey also told me it would have to be extensively modified to use on an aftermarket roller lifter setup (lifters with link bars) as they are made for the non-connected OEM style lifters.
