Re: Connecting Rod Alignment?

The manual doesn't specify the orientation of the pistons, it's a poor manual by today's standards... The T was on the passenger side and currently, I have only pulled #2. The piston is unmarked. I will crawl back under the car and check the rest of the T orientations tonight, but I am almost positive they are all slotted and all on the passenger side. I am planning on pulling some of the off center rods and checking the piston's wear patterns and wrist pins this weekend. The engine has a front and rear main plus a main between every piston. It spaces off the rear main with babbitt on both the front and back faces of that bearing. I checked the end play of the crank by pushing on the flywheel with both feet as hard as I could (braced against the seat) and measuring between the front facing babbitt and cheek on the crank, it's about .004" or .005". I could borrow a mag base dial indicator and check it that way if you think it would make a difference. I checked the side play of the rod bearings on the throws, they are all around .0025" to .004" by feeler gauge.
