My engine came out of a 66 charger and my 68 cuda had a 340 from the factory. The 383 didn't have the housing on it when I bought it. And my cuda didn't have a radiator. So I'm trying to figure out which side housing to buy. I too thought there would be less clutter on the right side. I know 440 source has some. I guess you could get the radiator to come out on either side.
