Re: pep roller rockers

I'm pretty sure they're cheap Chinese knockoffs. Stick with Comps, Scorpions, Harland Sharp, etc.

PEP = C.A.T POWER ENGINE PARTS

May be OK.... depends on a lot of things...spring pressure,rpms,lift...Mild build,hydraulic lifter cam...just might be fine.
Solid roller,7000+ rpms,600+ lift

Re: pep roller rockers

When purchasing tools, I have one rule - I always buy the best tool I can afford. I feel the same way about valve train parts. A rocker arm failure has such catastrophic consequences for the rest of the engine, that it's simply not a place I want to save money. I'd look for a name brand part with a good reputation. Besides, there are a lot of deals out there right now for SBC parts.

Re: Pep roller rockers

I've no experience with PEP parts; but, Pro Mags, Crower, Jessel = Big Bucks; and for the money, I think Harland Sharps are best buy if you're after 7G and you can run 600lbs springs with any of these rockers.

I run Pro MAGS with 210 seat and 520 on the toe with a 490 rate but then I got money tied up in my 7G SR MK IV Mill. As far as I'm concerned the OEM Valve train components (Rockers, Springs) are just fine with Cams under .500" lift, 112 to 118 seat pressures for FT but don't push the RPM's. I would say the CC 925 Springs are about MAX for FT and recommend quality Rockers like Harland Sharp and ISKY Push Rods if you intend breaching 6G rpm on a regular bases, machine your heads for Screw in Studs, Guide Plates and open the Spring Pockets to 1.439" for a SBC. The Guides must be in good shape and recommend guide tops cut for Perfect Seals. This does not include valves or a machinists capable of grinding seats per specs, CC'g, bowl shaping or porting ... etc.

Basically the Valve train has to be maintained to specs in a Hi-Perf Engine. Once set up a Solid FT or SR Engine is capable of running the season without adjustment. I would not dismiss that Hydraulic Lifter Valve trains can be over looked between seasonal maintainence intervals.

A stock 283 will rev 8G's but doesn't mean it will live ;o)
