Didnt know where to put this exactly, if it isnt right somebody may move it aye.

For anyone who doesnt know yet Jim Mock has released billet adjustable rocker gear for the 4 litre OHC 6.

Has 1.8:1 ratio and suits 7mm valve height setup.. guess thats AU Falcon etc.
nice if you want to wind it over 6200 or use crazy boost pressures.. its a solid adjustable tappet design so you can eliminate the dreaded pump up and bleed down you get under extreme applications.. in most cases they'll work with the hydraulic style cam profiles available out there in the market.
They'll set you back two and a half grand

Need a 8000rpm+ de-stroked solid cammed coon running these babies!

are they made of gold?

for that price they would want to have roller contact with the valve and needle roller bearing on the shaft.

yeah true its steep. who else is making them though?
It's certainly race application.. and you know what its like trying to open valves at over 25 pound boost pressures. Snap!

would you really expect any cheaper out of jim mock?

No but it's still fun to hang s**t.
