A good friend of mine asked me to post some pics of a friend of his who had the misfortune recently of joining the 2-piece crank club. Beautiful car, not so beautiful crank!

Ugh! Bummer. Pretty car though. I know you may not know until further inspection, but does it appear to have messed up anything else besides the crank?

Dang! You couldn't have sheared it off much better with a parting tool. Looks like that piston skirt may have "Kissed" the crank but if that is the only other damage you may have been relatively lucky. What were the conditions when it broke?

Ya, Tim, thats a bummer. As G.R. mentioned, please tell us the story of how it broke and if it did any other damage also. Was this a diamond shaped crankshaft, or one of the later ones with the straight sided crank throws?

I've broken two crankshafts, and both of them were diamond shaped ones with the "TW" mark on them which stands for Transue Williams.

Thanks Tim for posting, I was behind Bruce at the time, he was at an intersection turning when he hit low band and all kind if noise could be heard from behind him. I asked him about markings on the crank and he could not find any? Maybe it was and early after market crank? Since it is an early block he wants to install the Scat so hopefully this will not happen again.

Magnaflux the block carefully, that kind of thing is real hard on them. The Scat crank is a good choice, I recommend them for valuable blocks. That looks like a later pan. I have a narrow nose early pan, let me know if you need one. It's still on an engine I brought in, so I haven't had it on the pan jig yet. Some of them require a fair bit of work. Make sure whatever pan you use is straight.
