@DannyP no there is NO room formic of anything here, and after working on everything it is clear why Chuck made some of the dimensional changes he did. Something as simple as the placement of the beam and pedal board never made sense to me, but in its original format, like this car is, you can only fit a single circuit master cylinder and you have to modify the brake switch to clear the beam... this is just one of probably 20 examples...
Yes there is an underpan.
No driver controlled flap. With the 4 cam shroud you cannot have any engine mounted oil cooler, so this front mounted cooler is the only oil cooling the motor has. That is why I went with the 600hp Sterab cooler and I still have some worry about what oil temps will be...
