Graham Posted May 2, 2022 Report Share Posted May 2, 2022 Can anybody tell me if the strengthening rib and the recessed bores both came in with the CR block or where these changes done during the CP era ? Quote Link to post Share on other sites
cp25616 Posted May 2, 2022 Report Share Posted May 2, 2022 Hi Graham Can't say for sure about the rib but the recessed bores came in at CP75000 so later CP models. Alan G Quote Link to post Share on other sites

Alan G I think it came in in the summer of 1972 along with the modified head gasket and cylinder head. All to cut down warranty claims on BL? Bruce. Quote Link to post Share on other sites
cp25616 Posted May 4, 2022 Report Share Posted May 4, 2022 Bruce CP75000 was a 1972 model year car so production of recessed block and associated gasket would have been after the summer break in 1971 circa September. Alan G Quote Link to post Share on other sites
