Re: '36 221 - rebuildable??
As GB said the heads should match. It would and did run but not right or very well. Ask around here on the barn . Somebody should have a spare set they could part with I would think. Again nice work and keep us in the loop on your progress. Tim

Re: '36 221 - rebuildable??
eWell, I've gone thru this and can't come up with any answer about this engine. I have to know what the future of this car will be?? Dailey driver----------------- restored to original. Ur just a putzer old car,
I like the latter, Fixing this engine will be quite expensive, You might consider replacing it, any engine up to 48 will bolt right in, 49/53 will with some putzing/ good luck. But your in the right place now. Gramps |

Re: '36 221 - rebuildable??
Well, I think we passed the point of no return.🫣 We have all the parts already. Main bearings, rod bearings, another good used camshaft, crankshaft almost done machining, etc. I got most parts for a fair price and mainly without shipping costs. All costs are split 50-50 with my dad, so this is a nice father son project.
Maybe not the most logical way to go with this engine, since the car is patina'd 4 door Sedan, but we like to keep it stock. That's how it was parked end of the 60s, kinda nostalgic way to go. Verstuurd vanaf mijn SM-G781B met Tapatalk |

Re: '36 221 - rebuildable??
I’ve got the exact same mis matched heads on my lb 36 std bore steel piston motor. I ran that motor for 5-6 years and never could tell the difference. Of course I knew they looked different but it wasn’t till I removed the heads did I realize the chamber being different .

One chamber measures 95cc, the other 82cc. One response to my questions on this issue is: "Right banks and left banks.. can confirm slightly different cambers OEM stock.. ... it's because of the way the engine has been cast .. Ford engineered it that way.." Any ideas here? Thanks. Dennis Verstuurd vanaf mijn SM-G781B met Tapatalk |

Re: '36 221 - rebuildable??
Its always best to have equal chamber cc but back in the day you got what was available .
If you weren’t so far away Id trade you either head you want . |

Re: '36 221 - rebuildable??
Have you checked the combustion chamber total size with heads on engine? You may find they are close despite what you see on the bench.

Re: '36 221 - rebuildable??
I've collected 21 stud parts for quite a while trying to get one good block for my 36PU. I found a wide variety of heads of all descriptions. Water pump heads for domed pistons are not common. I think they were made by Ford to use on 37-38 engines with domed pistons to allow installation in 32-36 cars when using water pump block off plates on the block. I found one head that was clearly an aftermarket replacement head, it had a domed chamber. I saw other heads that seemed to also be aftermarket replacements, some resemble OE Ford on the outside, some don't. The chambers vary a lot in Ford heads. spark plug locations vary, the aftermarket heads vary even more. I suspect the aftermarket manufacturers sometimes cast Ford script on their heads, some have part numbers, some don't.
The Aluminum heads I've seen all were for flat top pistons, I've read here on the barn that assembly line 33-36 car engines all had aluminum heads, trucks had iron heads. All of the factory rebuilt engines I've encountered had Iron heads, so perhaps the new iron heads were a routine item to install on rebuilts and were cast for that purpose. My 36 had a Ford rebuilt engine in it, it had 1932 iron heads with 7/8" spark plugs on it. My guess is that they just paired up 2 similar heads and stuck them on as the engines went down the rebuilder line. With you being located in The Netherlands my data might have no bearing on your situation, the OEM engines may have varied a lot from USA production. I've seen enough identical rights and lefts that I don't think the different size chambers you have are normal. My direction if I were in your shoes would be to find a matching pair of heads or to find a match to your 82cc head. The average price for iron 21 stud waterpump heads here in the US has been about $25 If you are forced to use the heads you have, the 13cc difference might be just enough to make it idle a little roughly but I wouldn't bet a lot on that happening. |

Re: '36 221 - rebuildable??
Thanks for the input! I do visit the US on a regular basis, so it shouldnt be too hard to source one. Preferable the smaller chamber size indeed.
What confuses me so far is that some claim a difference in chamber volume is 'correct'. I might have to check it with the heads on the engine.... Verstuurd vanaf mijn SM-G781B met Tapatalk |

Re: '36 221 - rebuildable??
I do not think having 2 different chamber volumes is ever correct . It’ll work but not correct. Especially when rebuilding a motor and you have a chance to correct it .
