1969 Race Dart w/ 426 Hemi- garaged for 45+ years

Found out the car I bought a 68 Dart Hemi was a car that was most likely drag raced in the 70’s from work that was done. Car was a converted 6 cylinder car which I knew when i bought it. Had a fabricated deep sump oil pan with the hole for the suspension to run through it, swing arm pickup actually very well done and functional. Had correct Hemi mounts not elephant ears. The rear is a 4:56 Dana. but not a passenger car Dana it was swapped from a truck. No mounting points for the snubber on the rear so a steel block with a rubber pad had been fabricated and attached to the floor pan. Super Stock Springs, mini tubs, wheel wheels were cut but done very well with a roll underneath. Evidence of fuel pumps being mounted in the trunk. Gas tank was reduced in size to save weight and had a fuel tap for fuel inspection. All the signs of a fairly sophisticated build for the period. Floor had been cut at one time for transmission access. Magnesium crossram, correct carbs. Unfortunately haven’t been able to track down the history, maybe if I stripped the paint but I would rather not. Retained everything as I found it when the drivetrain and engine were redone including a heavily hammered set of Hedman Headers I had Jet Hot coated. Jet Hot saved those headers, highly recommend using them if needed. You never know what you will find when you dig into these cars.
Yes, that´s one cool car you got there.
Thanks.
