Correct Direction

Ok, so I ordered a bunch of Small Block stuff from Speedmaster on black friday:
Aluminum bare Heads
intake and exhaust valves
Stainless 1.5 rockers
Head and Main Studs
H beam Rods
Airgap knock off intake.

What I have:
64 Valiant Vert with 6 cyl 4 spd 8 3/4 rear with 323 sure grip.
67 273 complete 2bbl engine.

So time to start hunting for the next deal on the block to build. It will not be raced, just a good weekend street cruiser using the 4spd and 323 gears since it's what I already have.

Love to hear direction on what block I should look for to build, cam/lifter/spring, recommendations. Yes, money IS a concern, so I will be piecing it together as deals come up.

I do have access to a 340 block .030 over for about $400, but leaning towards a 360 since I should be able to find a good short block for a decent price.

I'd like to dress it up as an early commando as much as possible. I do have a ported LD4B intake i could use instead of the airgap.

Thanks in advance for your input.
