Crankshaft advice

[Greig Smith]

They look like the troughs of the Phoenix crank I have in my race car, except I spent many, many hours with carbide burrs opening up the holes and creating deeper feeder grooves into the bigger holes as I was concerned about the shallow troughs and small 90* holes compared to Austin's original cranks. Had it balanced afterwards. It also has a Forrest double oiler conversion with an overbore on the pump as it revs to 6500 rpm. No oil issues thus far
