I just got my 1955 272 back from the machine shop. The machine shop re-assembled the block, heads, valve train and front timing cover. There have been a few surprises:
1) The machinist did not re-install the small timing chain oiling ramp near the crank (the part was in a small box of returned parts). I think I have read that these ramps are often omitted in early Y rebuilds and that these were not included in Y's after 1955; is this correct?
2) The shop did not install the front oil seal slinger that I provided. It is my understanding that these were not used in 1955 but I would have liked to have it if it will fit. Since they were not used in 1955 is this a big deal?
3) By far the biggest surprise is the force required to rotate the assembly (although I try to limit this rotation). It takes 45-50 lb-ft with the plugs and pushrods removed to rotate the assembly; should I be worried?
I appreciate any help or thoughts.
