Converter upgrade worth it?

3400 converter from Edge in 727 behind 360 (approx. 450/450 crank) XS282S cam ported heads...

Andre must have asked me 50+ questions about the complete car.
Dont guess, be specific and honest with answers if you want it built right.

He nailed mine. Feels like being launched from a slingshot.
I'm a convert, no more manual transmissions.
High stall converters back in the late 70's/80's were total crap on the street.
Not anymore.
Completely streetable.
And FUN.
