AMT's Boss Nova drag car kit. I've always liked this kit and I've been meaning to build it for a long time. I stripped the chrome parts with oven cleaner a few years ago, but other than that it's been sitting in its box for ages.
It's a mixed bag, really. Most of the chassis is simplified to the point of being toylike, and the tires really deserve to be replaced. But the engine has nice detail, and I really liked the "Chrysler Firepower" engraving on the hemi's valve covers. It also comes with a variety of induction schemes, including a blower and crossed fuel injection, but I selected the eight-carburetor setup because I like that "forest of carburetors" effect (and the carbs aren't bad - all I did was drill out their throats).
I wired the distributor, but routing spark plug wires in a realistic manner isn't my strong suit. I added a few other details - some entirely bogus fuel tank plumbing, a coil, and a tank of some sort I found and glued to the back of the firewall. It could have used better seat belts and cans/wiring on the back of the instrument panel, at least, but I didn't get that far. Most of the decals are what came with the kit, the only exception being the Goodyear tire markings that I got from a Slixx sheet. I also drilled out the headers, but otherwise they're as they were supplied by the kit.
The paint is mostly Testors two-part lacquer spray paint, with various metallic paints on the engine (burn iron metalizer on the headers and Humbrol bronze on the carburetors), brass metalizer on the wheels, and Bare-Metal Foil for the window trim and rocker panels. I tried to save the chrome plating on the grill and bumper parts, but I ended up having to strip, sand and repaint the grill insert.
The best part of the kit is the Chrysler hemi engine; the rest is downhill from there. But it was still fun.
