Tom, ALCO C-630 produced more horsepower and had greater tractive power over the C-628. As I understand it, this required modification to the blower system. The C-630s had a reconfigured venting system on the hood bulge south of the cab. The Union Pacific sold 10 of their C-630 to the DM&IRR in the 70s as they experienced a power shortage due to EMD back logs on new power. I was able to find an MTH UP C-628 and did a little modification to turn it into a C-630. Your engine is a C-628. No problem since N&W had both. Nice job on the modification. I was determined to convert my find to a C-630.
