Yea your right, alot of people thought it was an engine size, there was no 442 CI, but with the 442 coupe, you got the four barrel carb, 4 on floor, and duels, all being pushed by the rocket 350 or 400, then if you got the 442 W-31 or 30, then you got the 455 Rocket, which was Un-Godly powerful. Almost to much torque. hehe
