First proper change after dyno breakin and its oil change. After a weekend racing + DE, with about 6hrs on the engine, sent sample to Blackstone for analysis. Lead (pb) was high enough to raise a flag. Engine builder confirmed this is ~ normal for a new engine and should settle.
Will continue to monitor and sample each change to establish trend.
Battery was mounted so that floor flexed. Cracked fixed and new plate installed. 
First break. Front Left. Happy it was in the garage. Snapped under minimal load, mounting tire.

For the Road Atlanta weekend, we changed the crank case ventilation from the intake manifold to a catch can, Turner’s. It was likely not designed for race use as ~50% of the oil aerosol passed through it and settled throughout the engine bay.
Sent the block out to be re-honed. Its condition was good and main bearings look so good they’ll be reused. The pistons have been coated in order to fill the small increase in cylinder bore diameter resulting from the honing.
Wheel nuts were not torqued. Fortunately the wheel stayed attached for the few laps of the session. Required replacement of the FR bearing, studs and wheel. May be able to have the wheel repaired.
Had the sensor replaced while the box was out of the car. Before installing the transmission, checked the voltage output on the position sensor. Found this sensor provided reverse from expected. Low gears, higher V steps down as gear position increases.
Replaced some seals and the sensor. Looking good for another season 👍
Sensor was original with the box. Proactive replacement while box was out of the car.
