Does anyonehave any experience with REV kits? 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.

I have the AFR Hydra-Rev one in my engine, but I'm installing it this weekend, I wont know till I turn the key. https://www.thirdgen.org/messgboard/smile.gif Here's the pics of it installed: http://24.1.139.249/images/120100/DCP_0086.JPG http://24.1.139.249/images/120100/DCP_0087.JPG http://24.1.139.249/images/120100/DCP_0088.JPG ------------------ West Coast GM Shootout 2001! 1991 Camaro Z28 5.7L 5-Speed (originally 305) 13.25 @ 107.18 MPH Southern California Member: SoCal 3rd Gen F-Bodies Webmaster: SoCal F-Bodies -=ICON Motorsports=- [This message has been edited by Kevin91Z (edited February 09, 2001).] |
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. ------------------ D&Z Performance "Putting Power to the Pavement" |
Check out Isky Cams too. They claim to have invented it. |
*Digs up old thread.* AFR has the same claim. Its who has the patent I guess. I am researching this for my own car. |
i hate to ask a stupid question....but whats the difference in the roller lifters and hydraulic roller lifters? |

ok i knew that much, cuz i've done cam work on my uncles 406 (wicked motor with low 6's in the quarter :hail: ) i just have never heard anyone refer to them as solid roller lifters and so on |
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. |
Low 6's in the quarter mile with a 406? Am I missing something? :D |
