GM Suffix Code

Hello,

I was wondering if you guys can help me with a suffix code on a GM 350? We just bought a motor to build and the casting numbers are 14093638 and the serial number is V0517UXH. I can not find the UXH suffix code anywhere. I have searched online and in my books, but I can not find this code. If I had to guess I would think that this is either a truck or van motor, but I can not find this exact suffix anywhere. If anyone can help confirm this number it would be greatly appreciated.

Thanks,

Senior
