I was reading the history during the summer. In 1949 Hudson claimed that the 262 inline six cylinder engine, that depending on the octane of fuel, they could obtain compression ratios from 9.3 to 1 to a high of 12.5 to 1.

We had 12.5/1 pistons in the Hornet for a very short time, it was a rare day indeed when a head gasket lasted more than 1/4 mile. That was with the 7D engine, the 7X had larger diameter head bolts but doubt it would have made much difference. Ultimately we reverted to stock CR. Packard's 8.7/1 for a flathead was really pushing the limit, GM stated that compression ratios over 8.2 or so were not practical in their flathead engines, though we also have to remember the gasolines of the time. As I remember the ARCO Purple and other super high octane gasolines came along a bit later and by that time flatheads from Detroit were dead. Our Hudson was a V8 Oldsmobile killer though in the 1/4 mile.
On the questions of PackardV8 on the engine bearings, it's just too long ago to remember, sorry.
