Converter has reached its limit

Opps = I missed the 904 part.
Indeed, it certainly would not!
I was 1/2 asleep when I posted the reply.

We explode the Pro Trans ($6,000)
904 about every 30/40 runs or so in our
Superstock car that is 575HP. I would guess
he is 700 to 750 HP?

When we are at the converter shop next week fixing
the Superstock converter again = i will ask him if it would
eve be possible to convert a 069 J to 904 hubs and splines.
But I doubt if it would be practical to do that.
I think not to convert it but to build it the same as the J may be the better option. Kim
