This is the MRL built 440 in my 71 Demon. 9.88-1, .030 over with Edelbrock RPM heads, RPM intake. Lunati solid roller 60331 237/243 @.050 .566/.578 lift. TTI headers into TTI 3" x pipe thru Dynomax Ultra Flow 3" in and out. No tailpipes yet but will have once on the road. Still needs some fine tuning on the carb to clean it up a little more. Idling at about 925rpm.
