Well they took a low compression sbc, and put the manifold vacuum to the vacuum advance on the distributor. This kept the engine easy to start, but put a good bit of power down under the curve. Compared to a normally set up combo.
I have done it a couple of times on vehicles I got with good running stock engines. The engine will have a tendency to surge in gear, but the extra torque is nice.
For low compression engines I like about 14-16* initial timing, and about 36* all in. A simple weight kit for 10 bucks works wonders.

Good to excellent timing numbers!
To control the surge just limit the vac advance amount to 10-12 degrees.
