What happens here

The presenter points out the Dodge R5P7 engine's distributor and notes a blue mark on the firewall where it makes contact. He also shows how the header is against the steering shaft. He explains that regulations prevent him from moving the engine forward to resolve these issues, as it would compromise the desired 50/50 weight distribution. The solution is to create a 'pocket' or recess in the firewall for the distributor and fabricate custom engine mounts. He highlights the bell housing tabs as potential points for new mounts.

Goal: Identify and plan solutions for the engine's interference with the firewall and steering shaft.
