Sounds like an "Offer you can't refuse"

The documentation is as comprehensive as skill and detail put into this project. Looking at this is like drinking from a firehose, how long has this projected lasted so far? Well done!

This is a good place to find current and past owner of crossflows.

Is there a u-joint on the steering shaft that allows the rack to be rotated? If so, the u-joint may be binding. Could the rack be shimmed up to space the shaft upwards without adding too much bump steer?

Radial tire flex due to hard cornering.

FWIW Loosen the mounting hardware of the rack and see if it can be slid sideways away from the motor. In the same thought, loosen the motor mounts and see if a similar shifting can be done. Good luck.

Intermittent electrical problems can be frustrating, maybe you could burn incense and chant "Lord Lucas". (I couldn't resist)

I'll give another vote for dodgy electrical connections. With the engine running, try wiggling wires related to the ignition (except ones with high voltage from coil and to the plugs) and see if it quits.

The Pemberton looks to be scary fast. Skinny tires, and lots of motor for not much weight, but is a good looking project.

I recall others have been down this rabbit hole before, put out a call for MD Inspection bumpers.

I have gone to wearing long pants when out on a blat to prevent scorched calf. This is after adding header wrap and applying thermal barrier material to the firewall and some of the tranny tunnel.

I think they are 185/70-14, it was the only 14's Tire Rack offered.

My guess is the system is pressurized during operation. The cap on the t-stat housing should have a spring to hold the sealing surface down. A new cap rated at 10 to 13 psi is an inexpensive experiment.

FWIW recheck the electrical connections involved in the clutch replacement and ground connections.
