I don't know but I have looked at them and I think they are their own castings based on Chrysler engines from some point way back.

Maybe some of the Crew lads will know. But I have often wondered myself.

I remember a Hot Rod built with one years ago.

Knowing Rolls I would expect the casting to be heavy. I did a bit of work on one once and it didn't half look like a 383 with minor changes. I wanted to pull a rocker cover off to see if the head bolts/rocker gear were chrysler like but the owner wouldn't let me.

In 68 they were fitted with GM turbo 400's
and later stroked to 6700cc from 6230cc to help with weight and emissions
its not a chrysler or Chevy or Olds...its a Rolls Royce

Phil Rutherford dropped a RR motor in his 32 roadster.

From what I understsand , a RR engine should not be taken over 4500 RPM , the reason may be longevity , smoothness , or just that the motor can't take the punishment (valvetrain) over this RPM.

No Neck will know more about this , as he works for em.

The 6230 - 6700 is able to with take up to 600 HP it was part of the criteria when built.

Really? I am pretty sure the one I did a few wiring jobs on was iron.

It was an old one mind. Not sure how old. Private plate and all that. Early to mid-60s I thought.
I must be remembering wrong.

But like I said I was not allowed to mess with it mechanically.
