Yea it's a transbreak, the old one was 4000, I haven't pulled the pill and checked the new one yet, Lenny from ultamate set the new one up for 5500, the old converter was out of round and was a basket case, locator snout would bottom out in the crank before the flex plate would mate up to the bolt holes, it was a 10" to and my new one is a 8", I honestly don't care if it runs exactly the same, but picking up a little et is always fun.
Lenny did my 8".. it was a 5000 stall but this
is for my Rampage(street rod) so I asked if he
could tighten it up to help the slippage.. this
is on a 518 trans so it has OD.. from what he said
it should be 4500-4700 and less slippage so I'm
good with that
