Respectable street car?

IMO, having had a similar set up in a 4spd car, a lot is in the gear BUT to do without will be difficult and you'll need a converter. Custom built may be in order. Since I'm not huge on automatic transmissions, I had Pro Torque (down the block from me) handle my needs after discussing things.

My last Edelbrock headed 360 used a .028 gasket on lightly milled (trued) heads. 93 octane was good to go.

Cam(S) were the MP 292/.509 Hyd. & then a Comp 294S/.525 lift. I had a slightly smaller Hyd. Cam in it as well. The MP 1/4 mile banked oval @ a advertised 288/.499 lift at the valve on a 106.

But I did have 4.10's and 28 inch tires. Weigh that against your 3.23's and current tire diameter. Which could be interesting.

@AJformS could help with how things could work between the gear, tire and other needed items. He normally produces a long but well informative read.
