JMM Products

[XR6xhute]

First I would just like to know are the products that JMM (Jim Mock) are selling any good or can you get the same products else where?

Here is what I would like to know. I want to do up a tickford head that I have and I would like to use my original XR6 Cam which is in great condition and also the XR6 rocker gear that is in great condition also. I want to buy his stainless steel valves that are on his site but I know from memory that the tickford valves are bigger by about 2mm, exhaust only I think. Are the ones he has on his site the ones I need are are they just for the straight six engines?

I want to get my head ported which I don't know much about, new Hi-Performance springs, adjustable cam gear, multi-layer steel head gasket, S/S valves.

Any suggestions would be great on what I should do to the hear to get the best out of it. The block has only done 93,000 and is in awsome condition.

G'day mate,

The general consensus with JMM is that his stuff is pretty good and definitely works. However, you may be able to achieve similar results for less dosh.

Have a look at the E-series 1/4 mile and dyno lists and you'll find quite a few JMM equipped cars at or near the top of both lists.

Cheers

Clicky

Unfortunately it doesn't list the mods for each car, but you'll get an idea anyway

me I have a lot of missmatched parts, different brands etc and manage a 14.8 @92 with a JMM Dev 4 cam, I think my car is capable of a bit more than that now after some maintenance servicing etc. It rips a nice skid too. :P

So IMHO JMM parts work, and they know there way around a 4 litre OHC engine
