polars , that original colors , but it was sold in 71 , but a 70 model challenger r/r 383 3spd , as i recall . when i bought , i had a long talk with the guy that built it , he had a stack of engine and trans build receipts . he built this 440 6 pack to put in it . well it got some small mods , headers , dual point accel and mallory coil , comp cams hyd , 143 t flywhl 11'' clutch , 6 pack a833 tranny . its a drum brake car , 8 3/4 r/e . he runs the car for a short time , and put the r's to it . and damages the head and some pistons , so its back to together again , and the same thing plus a rod and the crank gets screwed up . so here it is third time on the build , he spares no costs , new rm crankshaft and a set of carrilo steel comp rods . so he's breaking this whole new engine in , and beings the r's up to breaking the new parts , and his buds yells 'bring the r's down ' . now he finds out the factory tach is off big time . he would take this car for 6500 on the factory tach , high gear runs , with 3.23 n drum brakes , which was really 8000 rpm , so at 6500 it would been @ 160 , at 8000 , wow ! i parked it after driving it awhile , its been at 8000 . and never runs out of pull . i never pulled high gear to the top , but in third , it was 120 mph and nose up and pulling hard .
