440 HP Engines

[DBR/T]

Hey guys,   I've got a question regarding 440 HP engines.  I've got a 69 charger R/T that obviously is missing the original engine.  I think I would at least like to find a 69 HP engine to put in it. I've been told that the block should be stamped HP2, but I've seen blocks that were HP2 and just HP.  Which way is correct, and what stops someone from stamping HP on a non HP block?  I don't want to get stung when I do buy one. Thanks for any help and info,  Dale

All high performance blocks were stamped HP or HP2, HP2 simply means the engine was assembled on the 2nd (day) shift; no difference other than that.

So, the next question would be how to physically differentiate an HP block and a non-HP block, asides from the engraving...

they are the same , only the intenals changed , yes you can stamp a block HP IF you can  get the right size & font stamps

My block is stamped 505 HP.
