I have to mention the E-58 code 360 and the E48 code 318.Both were hd 4bbl engines.The E 48 engine can be found in many diplomat and fury cop cars from the 80's era.The E 58 came in the lil red express truck and was also available in some cop cars of that era.
There were also some crate engines put in diplomats for the florida DEA. These cars could top out at 148 mph.
