According to the info I have, the CJC isn't a 5.7. It's a 5.0 (305 c.i.d.) rated at 150 HP. It wouldn't be the original engine. The original engine would have been rated at about 170-180 HP. As for top speed, it's impossible to even guess without knowing what transmission and differential gear ratio the car has.


Tyler the 1977 Sprint came with 3 engine options for 1977 6 cylinder,5 litre 305 cubic inch and 5.7 litre 350 was the biggest engine option for 1977


True, but a CJC code engine should be a TBI motor from 1988.
