What rpm stall converter should use?

I have plenty of both!
I have a 1/2 dozen Street Strip Show


That car held the NHRA National Record in B/S @ 11.12 @ 119
Rules were very strict back then.
It won plenty of money on the street!

I run the Stock Mopar Hydraulic Roller Lifters regularly without issues as
long as lift is not over 550!
If they are used just inspect Roller and Pin Carefully.
I won a lot of money on the street too with that Road Runner. That was a quick and good running car, I’m glad I bought it from you, but sad after I sold it.
