What's the slowest car you've raced in the 1/4 ?

What was done to the 273? 85 mph suggest the car mid 15's without the tire spin
The timed run was with little tire spin during time trials as I rolled it out. The pass during eliminations is when it spun and I just let off of it.
The engine was a stock 180 horse 2 barrel bottom end. The heads were angle milled to a closed chamber with stock valves.
The cam was a Hughes hydraulic grind which I don't remember the specs. It had the 273 Commando valvetrain and the cast iron 4 barrel intake. An Edelbrock 500 cfm carb up top.
Stock exhaust manifolds and a 2 1/4 inch dual exhaust.
The 7 1/4 inch pegleg axle was starting to make noise so that's when I changed out the entire drivetrain.
