None of the hemi id lists I've found have every possible hemi. Especially for the truck, marine and industrial hemis. My 354 truck hemi wasn't on any lists (still isn't). I didn't 100% positively identify it until I pulled the heads and measured the bore & stroke.

I would guess that the M stands for Marine. A 354 with 2x4 carbs would be M45SP-3, 275 hp at 4400 rpm. For twin engine boat applications, engines were available in normal and reverse rotation pairs. There are some difficulties converting a Marine or Industrial engine to street use.

Recently I picked up a 354 hemi marine engine, guess about 56, with dual four carbs. The engine is in very good condition, with only minimal rust in the cylinder bores. I would like to have some more informations on this engine, like compression ratio and horsepower. The dataplate on the engine reads 45L different from any other Hemi marine engine, while the head casting numbers are 1733463, and this makes for a industrial engine. Can somebody help me? I would like to rebuild the engine for installation on a street rod I am building, so would like to know if it's worthwhile, given the high prices for hemi engine parts. Thank you for the help Antonello Jelitro mopar@xxxxxx <mailto:mopar@xxxxxx> |
