Rear gear recommendation old school build

I have a 360 here that was built almost 15 years ago, run in on the dyno and stored (made about 400/400).

It was built to run on avgas with 12.5 to 1 comp.

ported J heads, cam is erson hi flow 3h 477/477 lift 240/240@50

Rhoads lifters, Victor 340 intake with annular discharge 750 Holley.

Convertor is a quality 3500 stall and trans is full manual 904.

This car will be street driven maybe couple of times a month and strip maybe every two months.
I'll be running pump gas with water/meth injection system that I bought 5 years ago but never got around to using.

Advice please on what gears I should be looking at with my 8 3/4 rear.
Street tyres are 275/60x15 and strip are ET street 275/50x15.

And anything else I should really look at?
