In the video link of the engine starting up for the first time posted above, the 'keen-eyed' among you may have noticed that the generator warning light appeared to be staying on.
In fact, the light came on with the ignition & went out again as the revs increased (as it should) but when the ignition switch was turned off, the engine continued to run & the charge light came on again & stayed on - it seemed as though a small current was feeding back through the charge light circuit & feeding the ignition system.
As a reminder, my engine is fitted with twin MSD spark boxes feeding twin Blaster coils & a quick search on Pelican revealed that this was a known problem (& in fact is outlined in MSD's instruction manual) & is easily rectified (excuse the pun!) by the addition of a small diode placed in the warning lamp circuit - thoughtfully included (but forgotten about by me!) by MSD in their original packaging.
It also transpired that one of the 2 Bosch dash pull switches used to isolate the individual ignition circuits was faulty such that only one set of plugs was firing in the video clip.
With both sets of plugs now firing the engine is much more responsive & reacts immediately to even slight movements of the throttle pedal - aided no doubt in no small way by the lightweight 906-style flywheel & aluminium pressure plate...
Front & rear suspension/brakes are installed & the car is resting on its wheels & tyres for the first time :
Lovely, just lovely. What are the other specs on the engine? I seem to remember you saying that it was going to be a 6 but I don't remember if you are using a period engine. Judging from your attention to detail I would be very suprised if you weren't.

Basic spec (outlined earlier in this thread) is 2.5 litre short-stroke twin-plug engine featuring :
7R crankcases which have been shuffle-pinned & time-serted
Custom-made JE 90mm pistons (c/r 10.5:1)
Rebuilt/modified 40IDA Webers (36 mm venturis) on 'tall' manifolds
Ported cylinder heads with stainless steel valves and hi-performance springs
High-lift custom hand-ground cams
Lightened/balanced 2.2 crank with cross-drilled & grooved centre bearing
3.0 SC oil pump
etc
In it's original configuration with crank-fire ignition this 2.5 litre engine produced 220 bhp @ 7800rpm but I have since swapped in a period-looking Marelli-style twin-plug distributor operating through twin MSD boxes (which will be hidden from view) - 2 (dummy) Bosch CDI boxes & twin Bosch black coils will be visible within the engine compartment - so I am hoping for a little more ...

Do you plan to put 'plastic/glass covers' over the heed lights / cut away for the beams? I quick google seemed to show some cars with and without. I would go for with since it seems to me that lots of dirt could get stuck in there?
