Just get the Dart swinger going down the road. Engines ready, Trans is fresh, J converter worked over for my car. 3.91 fresh gears bearings 275 drag radials i had on the challenger a short time. Rubbed a little couldn’t stand it. Some nice Goodyear’s for the front race seats for the front and harness’s windshield, about a months work, probably less to hear it run, msd wired up, get the exhaust figured out as I have 2 chamber race mufflers 3.5” center in out 3.5” collector 2” super comps Bunch of nice junk to throw at it. Not gonna worry about the body, just mounting the glass hood and Daytona hinges properly. Brakes should be ok. 373 W2 BRC pistons Eagle forged crank scar rods Bullit sold roller, super stock oil pan, turbo action shifter and manual valve body. I hope it runs My 4.56 gears need gone through had a roar. Probably to much gear for the quarter with those tires. Finish the interior in the Challenger shouldn’t take to long.
