In my dart sport came originally with 8.25 and 2.45 open rear. Replaced engine with a hopped up 360, x heads, 280/474 cam 850 thermoquad and a 727 with a cheap high stall Dacco 2600 converter. Car was a total pig! Take offs sucked!! And on highway converter unlocked and rpms went sky high. Just didn't know any better!:(
We replaced a 170 with a 225 thinking the motor was a dog....it was the 'doba 2.45 rear also!!! you coulda tied that car to a tree with a rope and it would not be able to bust it.
