WAyne,
The canopy is just plopped on the top. Not shaped really other than to the curve. Not glued on or anything. The nose just looks long. It's 10.25" from the leading edge to spinner. The interior is divided into two sections. One side takes the pipe, the other the controls. Oh, and yes the cutout is a pipe exit, though it would have to be enlarged, This was just a sort of pilot hole. I had planed to put a sort of radiator grid over the area. It was originally set up for a side mount, rear exhaust .65. I have a straight header (no rise) that would allow the pipe to be about perfect.
It's been sitting down there for a long time. Truth is, the fuse is ridiculously light (what you see on the foam blocks there weighs about 5oz). I probably should finish the thing, but I would do it differently now. I've been try to figure out a way to incorporate what I want without starting over from the beginning.
