Beyond checking tread depth on tires check for cracking and date code, a lot of concern on running on old tires, many threads.

Driven is the new branding for what used to be Joe Gibbs oil. Has been regarded by many as some of the best oil on the market. Their HotRod (HR) series oils are formulated for flat tappet and older overhead cam designs with 1200+ppm zinc. It's one of those things where everyone has their own opinion on oil selection, but in the end it has the necessary ZDDP for an LT5.

Tires are a few years old, but only like 200 miles. The rubber still looked in good condition with no dry rot or anything. The car has been stored in a climate controlled garage, so the rubber hasn't been subjected to any real weathering to accelerate breakdown.
