My 1973 Challenger has been my pride since 1997 When I bought it for $1800 and dragged it out of the woods. I did everything myself with exception of engine / transmission rebuild. It's currently my daily driver and is looking at her second restoration in the next few years. The engine is the numbers matching 318 dressed up a bit. I put her on the dyno last year and she put down 243HP to the rear wheels. That's about 300-310 HP at the flywheel!!!! Not bad considering it was rated at 150HP stock. I added the suregrip with 3.91's out of a GTX years ago and it woke her up big time!
