Hi

Old rockers, mm, sounds like a few folk out there!

Kent 234 cam. My original rocker shaft is in good condition (amazing, everything else is knackered). Could I run the original rocker assembly with a 234?

I have been reliably informed that roller rockers are not necessary, but folks tend to use enormous aluminium blocks to mount the shaft to the head, with solid spacers between original rockers. Seems technically odd to me, given the original shaft is the same diameter and steel, don’t get why a new one would be stronger? Also, mountings are always in tension, trying to push them off the head, so original steel mounting posts very suitable?

Thx


Nic

I'd check with Kent Cams to be honest, they're very helpful

I've got standard rockers on my Vixen with a 234 cam, no apparent problems, on my 1600M I have an ancient Piper integral rocker system, looks fancy but I doubt it's much better than standard rockers. Steel posts and uprated shaft would be better but in reality overkill on a road car

when i was racing my Locost and westfields i had several x-flow engines in different stages of tune.

always used standard rockers, as long as the engine did not already came with steel rocker posts.


this said, those steel posts are quite cheap and for piece in mind its worth to install them.

if you have a high reving engine and plan to drive it for racing than the solid-spacers are usefull as well.
