MPL G50 Standard Engine
Standard 7R Engine
All parts are based on 1962 design, manufactured with the aid of AMC factory drawings. However all our 7R engines feature the G50 style lubrication system with external cambox feed hose and drain through the timing cover. Consequently all our 7R barrels, heads and camboxes are minus the oilways present in original pre 1963 engines, although the bosses are included in the castings to allow these oilways to be added if required.
Our standard 7R engines feature aluminium alloy crankcases fitted with alloy top hats line bored for perfect alignment. Needle roller drive side main bearings with oil seal, top quality timing side main bearings. The ultimate crankshaft assembly manufactured with larger integral mainshafts from EN36 forgings, pressed up 40mm needle roller big end. Carrillo con rod.
