Well it's not the toyota head I had welded together. I may try to use that one on a 170. This one is all Mopar and it's aluminum. Flow specs. 265 cfm @ .500 intake 164 cfm @ .500 exhaust That's before any porting. Does that give it away? Now I have the rockers off trying to fix a oil problem but here's some more pictures with the valve cover.

Wow. The more I see this, the more I'm impressed. Still don't know exactly what kind of a head it is...evidently some kind of a hemi, but what kind of a hemi head did you find with a combustion chamber diameter small enough for compatibility with a slant-6...?? More details plee-uz! (Or is it a trade secret...?) |

Wow, your not joking! Was having the intake on the PS your first choice or is that the only option? It looks like the pushrods enter the head almost in the center. How is that worked out? |

And what's that lettering cast(?) into the valve cover? Can't quite read it 'cause the photos cut it off. |

It's not enough valves to be a Neon type head. The only aluminum 2 valve head I know of that flows that much is the 5.7 hemi, but this one doesn't have enough spark plugs. I'm out of ideas. I'd take a hint. |

the top pan is a chrysler fire power hemi joined together but the head must be a small bore early hemi the 331/354/392`s were 3.94 bore and bigger, the fire dome dodge hemi had a smaller bore,that is my guess

Wow, that's even crazier than I thought. It doesn't look like it was made out of a 5.7 Hemi head as the intake ports are all wrong. But it is a two valve head. So that would mean it's a single overhead cam head converted to pushrods. The cross-pattern suggests it's a very modern design. I'm guessing SOHC Neon.
This one is all Mopar and it's aluminum. Flow specs. 265 cfm @ .500 intake 164 cfm @ .500 exhaust That's before any porting. Does that give it away? Now I have the rockers off trying to fix a oil problem but here's some more pictures with the valve cover. |

"the top pan is a chrysler fire power hemi joined together but the head must be a small bore early hemi the 331/354/392`s were 3.94 bore and bigger, the fire dome dodge hemi had a smaller bore,that is my guess" The Dodge 241 had a 3.4375 bore, so that would put it closest of the older Hemis to the slant. I think that it was the smallest displacement "early" Hemi (early 1950s). Hot Heads sells aluminum heads for some of the other "small/early" Hemis, but not for the 241, I don't think. Maybe somebody else does, but I would tend to doubt that the after market for that particular engine is large enough to make producing one financially practical. |

I know its not a 241 head trick...although Methinks Frank has played with that....  Lose a spark plug on these... |

I'll go out on a limb and say it is a diesel inline 6 cylinder head of some sort...with mods for sparkplug and the hemi configuration and so on, obviously I have no idea  ....but it's a work of art and I would like to build one...please fill us in....man it looks awesome HEMI SLANT SIX..........nico

Sandy, Are those heads from the current-production, "new" 392? |
