Hi All,

My '72 250 (130.923 I6, auto, carbs) project and I just joined the forum. Looks like a great wealth of info, and I'm greatful because my Haynes manual and crumbling owner's manual leave a lot to be desired...

One piece of info I can't seem to find anyware--okay, two pieces, are what should the actual cylinder compression psi be (versus the ratio, which is all over the web and in the books) and the acceptible psi difference between cylinders for this engine? Just tested them yesterday, and all were 130 with the excpetion of #5, which was 125. This concerns me a bit, because in the car's service records there is a reference to the compression being tested in the late 70's measuring 150 across the board.

Any info here would be tremendiously appreciated.
