Torque Converter recommendation

[Sixball]

I have a mid 70’s 454, oval port heads, dual quad tunnel ram with 650’s, mild cam, with 342 gears. I don’t know what converter is in it now with the TH400.

I have a newly built TH400 reverse manual valve body TH400 I’m putting in. I don’t know what converter to get.

It’s not going to the strip. Not a Daily Driver, just something to have fun with on occasional weekends etc…

Any suggestions? I may switch to 373’s in the near future.

This is an OBS Chevy 1/2 Ton with the Computer removed.

Thanks
