Need big block help

The car has a 3500 converter which is something I would change by looking at the dyno sheet and I like it as a convertible cruiser not a race car.

depending on the quality of the converter it could be fine and cruise like a stock converter.

all that stuff just for a convertible "cruiser? **** i'd be selling that motor and building a stockish 440 and probably still have money left over and less headaches in just a cruiser.
