I agree that the building/fabrication is 90% of the entertainment value. I got the SFI Spec, and built my chassis, narrowed the rear end, got everything aligned, did the sheet metal work, modified the fiberglass chute pack body, and then painted it. I also re-built the engine, changing over to aluminum rods and building the compression ratio that I wanted. I did have some highly qualified consultant help. Thanks to Foy Gilmore, Rooman. and the tech guys at Enderle who helped with the baseline tune-up. After a half dozen test hits we (my friend Brad Tidwell, aka Mongo) got it going straight and the last 3 passes were textbook straight runs. 4.90, 4,80, and the last one I think I kept my foot down all the way to the stripe LOL, 4.75 @ 146. All our local racing is 1/8 mile. I don't know what I would do if not for the hobby.
