At least the E48 motors did- the common cop car/towing/HP motor.
Yes there's a compression drop going to 360 heads on a 318. It drops down near where the compression of those 360s was. Outside of a handful most 360s were dismal low compression right down to where most people try to keep 318s away from. That's why Chrysler put 360 heads on them and called those 360 heads an improvement over the 302s. Don't think the E48s had just the 360-LD cam though.
Course, you go through as much work since the intake's different along with the carb unless you put an adapter on it. But yeah, the comment was exact for a reason- I don't think it's very much too insufficient, but insufficient at all is enough to be a negative.
