G10-250, The motor will be going in my 63 C20. I'm not sure what I'll be using it for. It has had my camper on it.

Twisted6, I figured you had 250 burned on the brain, particularly with the new motor. The 194 would be too much right now. The flat top piston looks good from the numbers. On your web site there is a picture of a combustion chamber in the lump port section. Has that chamber been worked on? What about dishing the flat section of the head opposite the sparkplug?
