VanattiWorkshop : nice video !
On your wooden engine test stand, have you got any detailed pics?
That stand sure seems to work better than I would have thought, and I would like to make one too!
{May I suggest a nearby fire extinguisher next time you test run the motor; I learned that necessity the hard way}

To the people mentioning breaking in a 235 cam; is that advise for some aftermarket cam, or a stock cam?
The reason I ask is that I can't seem to find any info in the Chevrolet Shop Manuals of the 1950's on stock cams needing additional break-ins.
