I can't find anything on the web about the numbers on this particular slant six. It's from a 1963 Plymouth belvedere and is currently sitting in my 1982 dodge d150. I'm just curious about the specifics of the numbers.

Welcome! I have no idea about what they mean. The casting number about the motor mount can be found in the parts matrix. Go the forum Home and look for tech articles, I think that is where they are located. |

Welcome to the forum. Stan has some good suggestions there. Seems like you may have a cracked exhaust manifold between cylinders # 3 & 4. Best, Greg |

[quote="Greg Ondayko"]Welcome to the forum. Stan has some good suggestions there. Seems like you may have a cracked exhaust manifold between cylinders # 3 & 4 I think it's just the picture, in person it's not there... I still have no idea what the numbers on the side of the block mean :-; |

2463430: casting number for 1963-'67 RG (225) engine. Not '60-'67; table is wrong. -11: tool number Other numbers in the vicinity: not decodable/not relevant, might refer to plant/shift/line. You might find more info on this engine by looking for a stamped number over on the other side, below the frontmost spark plug, just inboard of the coil/alternator bracket, on the block's top surface facing the sky. That might not be a crack there on the exhaust manifold, but I suspect your manifold-to-headpipe gasket is leaking, viz the horizontal soot streak on the block right at the level of that junction. |

Thank you so much, I knew someone here would be able to help, my exhaust is leaking cuz it isn't flat where the gasket goes and I haven't fixed it yet. Might just put black gasket maker on there. Thanks again so much |

Gasket goop will very quickly cook, and will not stop the leak. You need a flat headpipe flange and a flat manifold flange or this junction will leak. And just as it is very much worth your while to get the good gaskets for the manifolds-to-head and intake-to-exhaust junctions, so too is it worthwhile to get the good ones for the headpipe. |
