Finally got my 401M overhaul finished. Put on a couple hundred miles and all seems well.Ended up .030 bored,New pistons and rings,rod,main,and cam bearings.Ballanced the rotating assembly. 650 AVS2 Edelbrock carb and MSD ignition,keeping the points. 21/2 in exhaust with Jones turbine mufflers. I hope the tranny is going to hold. All I can say is WOW what a difference from the 305. It's got some burrs now.
