Hi All,

 

Those that are interested in valvetrain reliability for the perennially favourite  LS Motors, may find this recent development by CHE of particular importance.

 

CHE now supplies a Do-It -Yourself bush & trunnion conversion kit for factory LS rocker arms. 

 

The kit is precision machined in Southern California using proprietory metalurgy and removes the potential for standard  factory and aftermarket "roller" type rockers to spill their bearings and create untold internal damage.

CHE is owned and operated from Newbury Park, Southern California, by my extended family. They have been supplying discerning engine builders and racers for years.

 

Their engine components (lifter bore bushings, guides, seats, retainers, locks, bushings etc, etc) are throughout NASCAR, Aussie Touring Cars, Top Fuel - infact anywhere precision machining, reliability and horsepower are valued.

 

My Father, Sister and Brother-in-law head CHE in Australia and supply many of the best machine shops in Australia.

 

If you see value in quality gear and don't want to use parts made from ground-up Chinese bicycles, then give them a call.

You may also want to visit the CHE Performance Auto Website or Facebook page. Some of the pics of the AFR, Edelbrock, John Force and Boost Cruising workshops are pretty impressive:https://www.facebook...68772753418939/

 

Cheers, Scott

Engine builders may also be interested in some of this gear: seats, guides and various bushes.

No worries Garry.

 

I think the answer to your question, in part, can be determined with a set of callipers. In addition ask quality machine shops how much time it saves them to have accurately machined components.

 

Look what components racers use.

 

Metallurgy is particularly important with some of these components. Take seats for example - there are few opportunities for a valve to transfer heat. Seat material plays a very significant role in this respect. NASCAR racers report a 80hp difference from start of race to end in a 700+ hp motor. This drops to 40hp when using CHE seats.

Hi Scott, yes mate, i will most probably be going with Che in the xu1 engine anyway. They seem to make very good components, will call them when I'm needing the parts thanks again. Gary.
