omnicrazy OP super stock O Joined: Jan 2003 Posts: 969 mopar country	I am trying to id two 340 blocks I have but am confused. Some of the stamping are very hard to read. cast date 9-10-68 number in pass side of oil pan rail= BH29P9R162347 number on drivers side below head= FW340P26220125 Second block: cast date 2-11-72 number on oil pan rail= 2P453085 Number below head= HM340R39538015 Question 1) Why is there a difference in the number of digits by the oil pan? Question 2) Is there a direct connection between the numbers by the head and oil pan? I have been trying to figure it out in the little white numbers books but I am so confused. Any help would be great

In the later years they abreviated the VIN#.

Next stupid question why would one need premium fuel?

Also, for the engine serial numbers (not to be confused with the VIN) you can check the TSBs. The TSBs that deal with the engine numbers are always in Chapter 25 & normally one of the first ones in the chapter; http://www.hamtramck-historical.com/library.shtml

(unless you had the vin of the car) It depends. In a lot of cases I can tell what they came from for 1970 Hamtramck VINs. (as you know already) 1972, not so much, but I do not collect data on them. If someone did though..... That said, is this; Quote: 2P453085 2B 453085 or 2R 453085? P is right out.

Some of the numbers are double and triple stamped along with some random 2's upside down. We tried to take pics but they are too fuzzy to see anything. We also tried to do some rubbings but not all the letters would show up
