Compression and cam are currently stock as the internals of the motor are still original to 1968 specs. Around 8.5-9:1 compression, cam is .393-.400 lift with tiny 1.75/1.5 valves. Motor will be rebuilt eventually with 10:1 compression, RHS heads with 2.02/1.6 valves and perhaps a custom grind cam and converter to match the cam. RPM's at cruise speeds are unknown as I have not installed a tach yet.
