Question about carbs for tunnel rams

This is going to sound silly, but what will happen to the firing order by moving the oil pump drive?
I can't spin it 180* as the vac adv hits the firewall.
Also, is it possible to actually remove the vac adv unit all together? It doesn't get used anyway.

Moving the spot in the oil pump drive (intermediate shaft) will just move the position of the rotor a little bit. If you needed a lot of room & have the room to move the distributor 45*’s or 90*’s, the new number one spot can still be slide over a bit.

Sit down and just play with it and you’ll see what I mean.

And yes! Good lord that thing is really tight in there.
