Hello all Im a new member from Australia, with a 1953 Chieftain in partnership with my Dad. Our vehicle has only 53000 miles on the clock so far and is original. Its a P6 straight six -239 CID and obviously RH drive for us here, with the 3 spd Synchro gearbox fitted. I have just had the engine and gearbox out for some reworks and a paint job. My question is as this vehicle has the 2 BBL Carter 2010S carb fitted as standard, would it be the High Compression Cylinder Head fitted as standard (7.7:1) or the Low compression unit ( 7.0:1) Compression Ratio. When I look in the shop manual, my interpretation of the engine spec sheet shows the Hydra-matic transmission unit was fitted with the HC engine. I have the numbers in the 53 parts book ( Original GM book ) but I don't have access to the vehicle at present as its 2 states away. The engine specs show 115 BHP for the LC unit and 118 BHP for the HC engine. Apart from removing the cylinder head and CC'ing the chambers to clarify the Compression ration, maybe some of you experienced guys can help here. I am also seeking a replacement clutch for the car as the existing driven plate has not far to go before she is down to the rivets. Does anyone know of a lining supplier in the US or otherwise a reputable supplier for the manual clutch kits. E-bay is a good source for me in AUs but no one seems to list a clutch for the P6 driveline. Thanks
