Hi Carlton, the numbers that you list as being stamped on the machined surface on the front of the block are confusing. The correct stampings for a 300H engine should be S 43 ( the S means 1962 and the 43 means 413), HP (high performance) and a date stamping such as 2-24 ( FEB 24th). Check the H3 and the J2, perhaps the H is a poorly stamped 4 and the J is a poorly stamped 0. No HP stamp means it is not an H engine. Also, as you probably know, the H engines came with solid lifters.

The heads had previously been gone over and I could see a couple of new valves so I didn't think about anymore work on them. I will check whether hardened valve seats have been installed and if not, probably get that done. Fern Rivard had the block and crank checked at a machine shop before he provided them to me and it was their recommendation to grind the journals 0.010 (they are standard now but need cleaned up) and to take the cylinders to 0.040 over (they are 0.030 now). I intend to have the machine shop assemble the engine, so I want him to buy the rebuild kit - he is satisfied with all the various manufacturers - and will then also take care of any conflicts/problem. He sends parts out for balancing and said it cost $165 more unless there were some serious weight differences. So, I'm debating having that done. I reconfirmed the prices and kit contents (wrist pins are included) he gave me before and checked with our local Chrysler dealer and the Carquest shop I deal with and both people gave him a strong thumbs up. This engine work is the first major work underway; I do intend to have the trans redone by a pro too. The rest of the work I think my son-in-law and I can handle. I have tried to catch Fern Rivard by email but haven't had any luck in the last few days. Can someone help me with a few part numbers or point me to a source? block - 2205697-2, R.L. 7-24-61 (in the casting, on the side); 2-J2 and H3 (stamped on machined surface at front) rods - 1851595 LY DF 84/86 MS 3049 L (cast in the web, on both sides) heads - 2402557-2 (cast on upper head surface) crank - ? (have looked twice now but cannot find a part no. other than a few odd digits, 18, 6, 9 (stamped on the outer edges of the counterweights) - where should the part no. be? I'm sure Fern has given me compatible parts for the engine and I'm learning most 413/440/ and even some early 383' s had interchangeable parts, but I did want to know just what I had. As a final question (for now); how was the compression increase accomplished in the H motor? Thanks again for everyone's help.
