Engine # 99HE22 113508, which, via 'Guess Works', comes up as an 'A' series 3.44:1 final drive.
(Per GPS and Tach I run 3,000 RPM at 50 MPH if that sounds right for the gearing.)
On the same machined surface of the block, just in front of where the engine number tag is, beneath the temperature sending unit, "H66" is hand stamped into the block, is this if any significance?
Cylinder head is a 'CAM 4810' with "COOPER" and the numbers "8169" hand stamped at the back of the head, not by the thermostat housing. Block casting is WFM 1026/4 N W, if that helps. Both block and cylinder head have identical faded and worn greenish/yellow paint remnants.
I personally feel sure that this is a genuine Cooper Conversion but the head paint does not differ from the block paint. Wondering if block work was ever part of a conversion, though I understand it was not, yet there is that hand stamped 'H66' on the block. Can anyone confirm whether this is an "A" block or an "A+" block.
I get 150 PSI accross the board on all four holes and may have some slight valve guide wear as there can be a brief shot of blue out the back at start up, but she runs fabulously and pulls great. Can anyone tell me what Pistons this block may have come with, dished or flat top?
