I bought it in 1982 to build for bracket racing at National Trails Raceway, only 20 minutes away. Setback number one was finding two large cracks in the 383 block (freeze damage) on each side above the camshaft. Not knowing what else could be lurking, I scrapped the block and eventually found an HP 440 engine with 53,xxx miles.
Over the next two years, I gathered parts and built the engine first using the "Bible" (Direct Connection Performance Manual) to spec out a 13 second car with reasonable street manners. With access to gear-head tool and die guys who would machine Torqueflite parts on their lunch break if I bought lunch, I eventually had a "hemi" version Torqueflite (B&M parts and 36 pages of instructions).
With slicks, it would run 13.05 all day. My best time was 12.95 at 112 MPH.
After taking early retirement from my engineering job, I started a metal fabrication shop, so the Challenger (minus the built Torqueflite) took a low priority. Today, I'm totally retired and making time to get her back on the road (and occasionally to the track
).
