Learning Curve . . .

I'm building a new? motor from broken parts again.  I guess that's the best way to learn this craft by doing again and again.  We'll run a vintage Sifton 412 cam (dated 1973), Wiley dynamically balanced the flywheels (his secret %percentage), McFarland milled the heads and I cleaned up the ports a bit for Rowe nitrate and  HD valves, we'll try the magneto again.  I bored the cylinders +.010 for 8:1 Gary Bang pistons - and my trusty Super E . . . all this for an extra kick in the britches. Thanks to all the new people who sold me stuff that's been in their sheds and basements and abandon houses for years and years and just want to see me go go go go go go . . . .
