But he would have been had he actually campaigned the car in the class.

The engine was supposedly "fresh" - the pistons and rods certainly look like they are fresh, and there is other evidence that case was split and resealed recently. The rockers and rocker shafts look anything but fresh...

Pistons have thus far measured up ok. I have to check cylinders, but they look fine. I am going to pull the rods and check the rod bearings. Otherwise I think this thing is going back together with the same P&Cs. From my few discussions with Rothsport, they said the engine was "leaving a lot on the table" Hopefully new cams, some headwork and twin plug and retune of ECU will wake it up nicely. It wasn't slouchy at all, just not ready to drag race against the Caymans.

Still need to decide whether to go new on the exhaust, or find someone who can competently repair the Cox system.
