Just wondering if anyone knows much about these and if anyone has ever used them - was going to buy Rollmaster but these have come up for sale close to home @ $300.

Cheers, Cheyne

Sorry Cheyne, haven't heard of this brand.

Other threads have indicated that JP units are prone to early failure, so I'd stay away from them (just in case).

I wonder if it would be better in the long run to play it safe and buy a known brand that's got a bit of history, (such as Pete Jackson)?

Mate, having run a JP set on the street for 2 years.........the gear faces got chewed out with lots of little metal bits running loose! They can transfer a lot of harmonics etc onto the crank and bearings and increase wear.

I fitted a Rollmaster and all I can say is.....heaven.

As Rhett said, unknown parts dont get a second look in a performance engine.

These teeth faces should be as smooth as a mirror.

Cat Performance make quite a bit of hi-po stuff now like gear drives, main stud girdles, etc. I've been told it's good quality but time will tell.
Rollmaster make a kit with a torrington needle roller bearing that goes between the cam gear & block instead of the usual rubbing plate. A lot less friction & wear. The part number is CS3085.

Thanks guys - I think i will stick with the rollmaster, i had a look into the Peter Jackson gear a while ago but they seemed quite pricey in comparison to the rollmaster?

As for the CAT Perf stuff i hadnt seen anything from them prior to these popping up - for anyone interested heres the link to their site : http://www.catpep.com/default.htm

Just dont seem to hear anything good about the JP gear aye?

Cheers, Cheyne

Thanks for the link mate. They sure do have some tempting prices. The Testimonial section sounded really good, but I just can't blindly believe anything on a vendor's website.

I wonder if anyone on these forums has tried one of their stroker kits ?

I fitted a set of CAT extruded roller rockers on my old 302 windsor. Never had any problems at all, even when it broke a rocker stud.. Thats the same with Pro Comp dissy's and their PC6AL's when i got mine re-graphed the bloke said "OH NO NOT ONE OF THESE" then went on to show me what wasn't done etc etc and said "oh this one is perfect they must have got their act together" They were the only cheaper brand products I brought... I might have been just lucky never know.. Even MSD had a bad batch.

CAT makes great products.... i have several products on my car..


they make super good roller rockers.. better then gold race..

i also have the gear drive..
its kinda a piece of crap.. but it works nice... but u have to press the crank gear on and get the top one milled.. i dont know if they
fixed that but the top gear crank mount was .014 to small for a 351 cam but ive had it attached to my $350 custom cam and it has worked for over a year now no problems but thats what u get for 40 bucks.. a lil machining .. makes u feel like a man... lol
