Errr... Mine wants to move and the revs fall a bit in D or R. Not right ? Drives fine....

Its fine morg thats normal on a factory converter,+

Yep, there will always be a bit of an rpm drop as you drop it into gear, that is normal. I'm talking about a big RPM drop, where the motor is really labouring as you engage drive.

Think that's a Range Rover convertor you have there Johnny. It is a Mopar convertor but without the ring gear. The Flex plate on the rover has the ring gear on it.

Yes I think your're spot on there, any ideas how I might be able to use it ?
I'll have a look to see if I kept the flex plate. Bit of a long shot if the diameter and tooth number was the same as the Mopar

The flex plate will be no use to you the ring gear will be in the wrong place and probably the wrong diameter. You could probably get a new ring gear and weld it to the convertor, not sure if you should do that without cutting the convertor open first though. you could take your convertor into Sussex autos and get them to sort it but that would probably cost as much as buying the a new convertor that's right in the first place.

What about potential balance issues on a Small Block?

Humm, I'll have to have a look at the original one that's on the car , and the high stall one , together, and see what I can do with the ring gear off the original,or buy a new one.

what would you recommend stall speed wise ?
