The original Yenko 427 engine is almost done...my drivetrain guru Dave McGaffee says it will be on the engine stand this week to break in the motor. Dave and I spend time at the track together...doing 1/4 mile passes in the RG Copo

The original headers are being massaged by our local fabricator. They are in nice condition to begin with. On the Yenko paperwork John was charged $172.00 for headers and deep tone mufflers.
