You sure that's not "M8" ('59 315 or 354), not M3?

There are a lot of early hemi ID codes that never made it into any database. At least none that anyone can find now, so don't be surprised if you can't find that code. It could be a Canadian code or a replacement code.... who knows. The good thing is that if you're going to convert it to use in a hot rod any specific truck stuff won't need to be used and basically once you replace the normal stuff, pistons, cam etc. you'll have a typical 354. However, if it was a truck engine, check the heads and if they have a rectangular heat passage in the center (manifold crossover heat passage), you'll have to use a truck specific intake manifold. The standard car style manifold will have a mismatch with the heat passage, but you can have the top section of the water passage welded up to solve that problem, or just pick up a set of "car" heads.



Here's a pic of three early hemi intake manifold gaskets to illustrate what I'm talking about. The top gasket is a 331/354 car, the middle is a 392 car gasket and the one on the bottom is the truck gasket. You can easily see the mismatch and why the truck head needs to have the top section filled in order to use a "car" performance intake manifold.
