Yeah that's what I thought - but wasn't sure since I have never worked on an engine this old before.

The only the grinds that looked kosher to me were the straight cuts (with inspector marks):


which is what I've seen done on the 60's era v-thingies I have wrenched on in the past.

I guess I'll just hand it over to the machine shop to get it balanced. Should I ask them to take out any more weight?

I am following the guidelines laid out by Roger Huntington, Floyd Clymer and Bill Fisher in terms of 'souping'. Roger suggests in his book that the crank can be lightened by as much as 5 pounds - but says: "This is not widely practiced ahd we won't recommend it one way or the other, since the performance improvement would be very slight at best."

What do you think?
