Another way to skin the cat; the High Torque 292 LS swap

[larryboy_3t5]

Hey, looking to do a similar swap and my issue is leg room in the cab. It looks like you had plenty of room in that area behind the driver's side cylinder head to mount your coils. If I didn't do that, would I be able to push that area of the firewall, where the throttle pedal attaches, forward an inch or two without interfering with the back of the engine? It almost looks like the firewall could be flush all the way across behind the engine in your photos.
