70nova,
I ran a few numbers on your (233cid?) engine in the Gonkulator, just to give an idea:
As in in the video:
Torq 225 at 3400
Powr 168 at 4900
That assumes you can richen that MV carb enough to be happy.
Add Langdon dual exhaust iron

Now some intake choices -
First the Offy 4bbl intake with a Rochester 2gc on there, the little 283/195hp carb:
Torq 246 at 3600
Powr 211 at 5200 (a big improvement but there's more)
Or the Offy 4bbl, 390 Holley, a classic small engine combo
Torq 253 at 3800
Powr 236 at 5400 (wow, a big kick)
Or, the pair of 32/36 webers
Torq 256 at 3900
Powr 249 at 5700
That is well over 1 HP per inch out of an "old school" setup, no Street Outlaws ProCharger, no Fast&Furious NOSS, just good old hot rodding, from the good old days.
