Hello all... I am new to this forum, but have been reading it for a while; just registered today. I have a 1974 MGB with the 18V engine. I am in the midst of a restoration, and will have the engine apart to refresh bearings, rings, etc. I have been reading the Power Tune you MGB book bu Peter Burgess, in which he talks about how the 18V had basically the same cam as earlier versions, but the timing was shifted. He states that in older version, intake max lift was 110 deg ATDC, but in the 18V it was changed to 106 deg ATDC, which improved off the line torque, and decreased emmisions slightly to the detrement up upper band performance. I am considered changing the cam timing back to 110 ATDC by way of an offset cam key. Has anyone tried this? I'd love to hear anyones experiences!
Thanks, Dave
