RV8 Roller Cams - Anyone tried them ?

[rev-erend]

I've been searching on the net for RV8 Roller Cams but not much info on them ..

Anyone on her tried them ?

Who makes them / imports them ?

Any disadvantages.

Hi there. A friend of mine had a set of KENNE BELL roller rockers to suit RV8 that he never got round to using. I'll find out if he's still got them if you like. He was talking about selling them at one stage.
They could go nicely atop a roller cam.

Try searching Buick 215 fitment too

The main disadvantage as far as I understand it is cost.

I think the cam profile needs to be designed to suit a roller follower so presumably you'd want to get the cam and followers together.

Also, Rovers have small cam journals which means the lobe journals have to be small. There will be a lot of acceleration involved which needs to be controlled.

Fit a turbo, it'll be less painful and make loads more power ;-)

I already have PEP roller rockers on Wildcat heads .. so no need for KB's.

Roller cams just seemed like a great idea but not much out there on them.

In more detail.

Many moons ago I was looking at the buick roller cams, the v6 items. The rover cams have journals which get smaller towards the rear. Iirc the buick v8 cams had 'same size' journals whereas The v6 ones were like the rover. The master plan was to explore the possibility of having v8 cams ground with v6 profiles etc. The issue that I saw was that rover cam journals are quite tiny which means that the cam lobes can't be large. I was concerned with velocity issues and wondered just how much spring poundage would be needed to keep things under control. Then I looked at rev kits and welded plates in the valley as a way of controlling the cam events. I concluded it was all 'doable' but with risks and also costly. There didn't seem any point in revving the nuts off my engine.

That said, I bet it's satisfying for those who have got it up and running :-)

That would be much easier if somebody offered a manifold kit ... ;-)

He he, I gave up on that project Peter. People want cheap and cheaper still to the point where it's not viable.

Could do I suppose as I have a Turbo lying around and a space at the front of the engine

^ That's nearly as big as your engine Sir :-)

It was small but got greedy.
