I've been building for years. I like trying for realistic details, but I also like to build for fun. I used to do good in contests, but the real modelers have long since passed me! If you get a chance, most car shows have model contests, check it out.
Here are pics of my 1966 200 CID in my 1966 Mustang Coupe. Weber 2V on milled/ported/modified late model head; big valves; cam; flat top pistons; 6 into 2 headers, DUI distributor, double roller timing chain. Not driven much yet, car's in the body shop!
