I pulled an engine today which isnt the original from an old pickup laying around. When I pulled it I noticed a plate on the side of the block that said chrysler industrial and also HB 225. Any difference between these and a regular 225 slant six?? |

It depends on what it really came out off, but some of them have some things a little better than the norm. Most industrial or heavy duty stuff was atleast built with hand picked parts, like blocks & heads that where better castings, cranks that needed very little balanacing and where straighter. Then some stuff had things like the crank & rods that where shotpeened for even more strenth. Is this a Yello engine ( color of block paint)? If so these are the engines used in th eheavy duty trucks Mopar would build ( like a ton truck or something).. They seem to always be of good castings and parts and holds a good chance of being so. Anyway the slant six stuff is so good that hunting down this little bit better produced parts is not really needed, but better is always better so if you have a good one it should make a good one to build. The blocks having the chance of being a stronger and thicker casting is a good thing to look for, and the crank not having big drilled holes for balancing that will weaken them is something to look out for also. You can shotpeen anycrank to gain the extra strenth, a good core is the best place to start no matter what it was. The best block, head, and crank that I have are ones that came from one of the early Yellow truck engines. Another good block I have came from a 68 Cuda though so its not always the end all to the best pieces, but they stand a good chance of being so. Close inspection is always a good thing when it comes to stuff like this. For example a thicker block (in the cylinder walls) will allow a bigger bore. The HD blocks had to pass a inspection and have no areas that needed welding (for repairs to save a casting) and have no, or very little core shift when it was cast, and it might even be possible that the metal itself was harder (more nickel in the metal mix) which would help it wear better and be even stronger . I look forward to building the engine I found like this because it has the thickest cylinder walls out of all my blocks. It will be my hot engine build (the most power ) when the time comes and might even be the one I use for my turbo setup. I may save it for the second engine I build for the turbo just incase there is something I do wrong and ruin a block from a bad tune or something. Sounds like you have a chance of a good setup. As far as higher horse power engines they didnt do that and all castings are basically the same for the years intended except for the small differences in which pieces they chose to use . Although on the heads the newer combustion chamber head is what is said should be used, the head I have off of the Yellow engine I have flows much better than all the other heads I have. You can even see the diff in the ports (although not much difference) if you look at it close. I dont know if it will be better after port work and bigger valves are used, but in stock shape it flows much better even though it has the older combustion chamber. We are going to use it to shave .175 thous off the deck of it when we build a high flowing head. Its combustion chamber is only 54cc to start with instead of the normal 58 to 60cc of my other heads.

This engine is red and is the 5 freeze plug block with the typical steel crank. I do happen to have a yellow early '60's slant six from an unknown dodge truck truck as well. I have the head with it also. I have about everything to with the red engine except the head. Im basically trying to pickout the best stuff to build a bulletproof high horsepower slant six. I heard lots of the industrial slant six engines had shot peened rods and crank as well as some even having a double roller timing chain. Dont know though because all the ones I have seen have been aftermarket. Thanks,Michael |

The engine is a 2806830-3 and has a U on the side, whatever that means?? It's a 68-75 from my gatherings? |

"U" blocks are pretty common, generally a pretty good casting. Check it over for defects and build it. DD |

I have another complete engine with BH on it. Is this a good way to go as well?
