Bump, still looking !!

Jon Brakke had big reverse rotation cams when he was running the Hewland. Probably not a TB-30 but maybe a big Howards or something.
It's been a long time but I know the Hewland did not go with the Corvair.

Thanks Jim,
Thanks for the reply.
Yup , I now remember that scenario.
This need is specifically for a Turbo reverse rotation 3.0L drag race engine.
Pushing 15-20 PSI of boost.
I have a TB20, but wish to go bigger.
The search continues !!

Bob, Make your own!

Make a sleeve bushing to press over the non drive end for a press fit and bearing change then turn down the drive bearing to the smaller dimension. Instant reverse rotation cam.

I have one here just like that from Otto Parts!

Hi Ken,
Yes I can do that, easily.
To a OT30 I have hear.
But the OT30 has a different exhaust lobe than the TB 30.
So I really need a TB30 to reverse it RR configuration.
In the interest of time, I am trying to press "the Easy Button ".
If it doesn't work, I will seek a TB30.
And change it.

For what you are doing, the OT-30 might end up being a better cam than the TB30!!

In my little turbo knowledge if I was drag Racing , I would turn up the boost (Billy Bruce 30lbs) with a tight lobe center cam and blow the excess out the exhaust. Billy has no boost control and distributor timing is locked at 32degrees !!

30 PSI will sure get the job done.
Gonna start lower 15 psi and add boost as needed.
Starting with F/B combo, then going to aftermarket E flow turbo.
Probably need some kind of exhaust pressure boost controller.
