I recently picked up a 72 challenger in decent shape and want to add some snap under the hood. It has a weak 318 in it so that's going to be yoinked asap.

A buddy of mine gave me a 78 model 440 from a motor home, the engine and transmission only have 2800 original miles on it so it looks brand new in and out. I've heard these engines are low on compression and sort of whimpy? What can i do to this thing with out boring it out or milling the heads to raise the compression etc. I could buy new aluminum heads if needed just not sure which ones. It currently has the 452 heads on it.

I want to be in the 450hp + range. The reason i do not want to machine work is due to the fact it seems impossible to find a decent one around my area.
