Hope you don't feel like you are being neglected here.  I will be getting an engine one of these days that is supposed to have come from a '58 Ford, so could be 113s.  I'll let you know.  They'll be available, but shipping cast iron can be salty.  I'm in east central Indiana.

You might try CTC Auto Ranch which is located just north of Denton, Texas and next to North Star Dragway just off of I-35.  Their phone number is 1-800-482-6199.

I talked to Mike on the phone and offered him a pair for $150 and then I thought of you. Shipping is going to kill this deal and if he can wait till columbus  can you take them back to Texas? I'm just looking for options to save him a dollar or two, and give you some fuel money instead of the mail or UPS

I got my engine today, it is not a '58.  I believe it is a '55 292, the heads are ECG-H.  It has a '55 distributor and a '57 "B" intake.  I'll bet it ran rather poorly.  Anyway, it appears you are getting some 113s from Kevin.

Kevin's idea or using Columbus as a relay to move parts is a good one.  If I can be of assistance in parts relays, just ask.  I can also bring parts to Columbus, I have many engine parts available.
