Bj and the bear K100 questions


Recommended Posts

What is the correct wheelbase for the Bj Mckay aerodyne? I'm going to restore the one I built as a kid. By eyeball it looks like around 180"-190" but I'd like to know for sure.

Also I see a couple suppliers for replacement decals for this truck. Any recommendations on which ones are best?

The engine is an 8V92? And should be painted silver?

After what I have found out the BJ truck had the standard 180 inch wheelbase.
And yes the Cummins "big cam" NTC 400 is 855 CI, but the Cummins engine in the K123 is a NTA 370 wich looks slightly different than the NTC.

You can use the NTC 475 Twin Turbo from the Revell AG Peterbilt 359 and KW K100 and skip one of the turbos and you will have a NTC 400, if you don't have that one you can use the NTC 350 from an AMT Peterbilt 359/White Road Boss and Western Star/Diamond REO and modify the aftercooler to look like the newer ones on the NTC 400.
