Well... Car's still under repair. I'll shift this discussion over to "Member Restorations" even though it's a resto mod at this point.
As noted, I added MSD, bigger intake manifold, bigger carb to the 318. The engine is still missing on a few cylinders but compression test checks out ok and all plugs, wires, etc. have been replaced and retested several times. Best guess is that a car that has sat a long time will have developed varnish that may be causing the valves to stick enough to prevent firing? So trying some sea foam in the oil and to run the car at idle for a tank or two and see if it clears up.
For safety inspection I ordered and replaced the seatbelts with original style replacements from Seatbelts Plus (not a perfect fit and doesn't appear to support the wiring for the seat belt warning system). Got the wipers connected and working again (was missing a clutch). And serviced the brakes (rebuilt lines and new MC and rear cylinders).
Meanwhile I've commissioned a Machine Shop down in Rosenberg, TX to build me a 440 stroked to 493 and planning to swap to 4-Speed Manual, swap to QA-1 suspension front and back, upgrade to a stronger diff.
All this I'll address in restoration Forum.
