Re: {Chrysler 300} Engine standings ‘64. 413s

as far as I know all B blocks are identical , unlike 331,354 ,392 300 engines built be chrysler marine , with special casting metallurgy. And obviously solid lifter heads etc . Truly HP or HD

At GM same thing applied to Cadillac engines

At one time you got what you paid for

B blocks had changes but generally applied across the board ,

300 's had special builds cams etc

That is Why the HP ?

stamps for a H and a P are under 10$ each ? just sayin ..

Most, if not all, 300G's I have seen, including the two I've owned, are stamped R41HP on the pad.

My 1967 Dodge Coronet RT had the HP stamp on the pad. It’s stands for high performance and was used from 1966 til 1971 on the 440 and 283. I could be wrong, but I don’t believe it was ever used on the 413

Question - I am aware of the usual “V41” stamping on our 413s. I have a couple for sale and a potential buyer has said he wants an “HP” motor which makes me think he expects that as part of the stamping. I have never seen that stamping, which is why I am asking all of you whether it was done and, if so, what would that distinguish such motors from standard K motors. I have no ideas here, if someone can help me out. I DO know that HP usually stands for high performance, but why would the stampings vary, unless it was for the ram motors, in which case I would like that confirmed.
Thank you all,
Pete Fitch
