This project grew out of another C-600 build I've started, though both are based on the 1/25 AMT Ford C-600 kit. This version will use the longer frame rails found in the City Delivery C-600 kit which have already been fully boxed in, as shown below. The lower rail has been sanded smooth, while the upper rail was not yet sanded when the pics were taken:
I'm using the turbine engine from the AMT GMC Astro 95 kit to power this truck, so I will be doing a lot of test fitting and modifying things as necessary to allow the engine to fit under the cab and between the frame rails. I debated widening the frame, but found it wasn't necessary once I had the engine mostly assembled. There isn't much side-to-side clearance, but there are no interference issues so far, even when the exhaust manifolds are placed in position:
After adding the regenerators to both sides, there's even less space between the engine and frame rails, but the engine's fit and location within the frame is about as good as it can get. I will likely need to add some small lift blocks between the front beam axle and leaf springs or arch the springs a bit more, and a small blister or two might be necessary for under-cab clearance, but the front and mid-engine mounts are now in place:
There are still a bunch of accessories to be added to the engine- alternator, starter motor, etc., and the rear wall of the cab will get a larger opening, some louvers, and a new support brace, but for now, I'm happy with how it's all coming together.
