yes. the mystery motor was the modern big block Chevy like came in the later 60's. 454, 427, 396 and such. I know they first appeared in the "mystery motored cars. The first production car was the 65 Chevy Malibu if memory serves me right?
Bleach will remove chrome, 90% rubbing alcohol will to. For the olds motor not sure if the new 70 drop top would be period correct but it has the best detail.
I received my Fairmont yesterday and pics do not do this justice, I have bought resin before and this is for me the cleanest body. The underside of it is like a styrene kit, smooth and thin and no warping and the grille and tail light panel about drop in out of the box.
If memory serves me, Rusty's first race in winston cup he finished 2nd, to Dale Earnhardt, Atlanta not sure though. I would love to build that Wallace car, it was 1982 I think.
