Need advice from some experts

I'm building a engine for a future fibergl*** 32 ford 3wc.
It will be my daily driver, but I want some perfomance (burnouts reliving my youth) and a nice sound (lope) without to much gas usage.

This is what I have so far:
1. 1973 sbc 350 bored +.30
2. 1973 heads 3998993, 75cc
3. cast crankshaft 3.48' stroke med journal, two piece seal bored - .20
4. Ederbrock dual plain Performer intake manifold
5. Holley 600 cfm 4 barrel, vacuum secondaries, single pump, manual choke

This is what I'm planning:

1. pistons - Keith Black Dome 6" Rod Pistons +30
2. COMP Hydraulic Flat Tappet Cam - 270H
3. steel roller rockers arms 1.6, 3/8, self alianing
4. TH350 automatic


What is your take on this setup (budget is important)

 

Engine sounds fine. A 700R with just above stock convertor would be a good ****** option.
