I have two rebuilt motors with transmissions. One is a '26 bored .040 over, and the other is a '25 bored .080 over. Otherwise the rebuilds seem to be exactly the same. Is there any reason to keep one over the other? Thanks
26/27 engines are more desirable and it is only .040 over. I would sell the '25.
What year is your car?
26 is a keeper at .80 over I would get rid of the 25 engine
To avoid the confusion and stress of weighing the various recommendations, I will make it easy for you. Just sent both engines to me. Thanks Mark
Keep them both. You should always have a spare on hand!
I would keep both of them. One of my T mentors would say "You know that they are not making any more of these".
Unless you're looking for the cash or some more storage space I agree with keeping both. In fact I'd use the .80 over because if it fails chances are it'll be toast anyway.
A good extra engine can be the start of a new project - they tend to multiply
Why are the later engines more desirable over the earlier ones? Confused mind wants to know.
The two bolts connecting the hogshead to the engine block and the wider brake drum with lug shoes inside for the clutch are real improvements on the 26/27 engines. In model year '27 many engines got cranks made of EE steel, they're less prone to crack from fatigue.
The new shape in the crank throws from 1924 is also an improvement over earlier diamond shaped cranks. Vaporizer carbs mostly found on 1927 engines are the only '26/'27 feature not generally considered an improvement (though they do have a few fans)
Thank you Roger.
Thanks for all the advice. I'm going to sell the '25. It's a strong motor, but I need the room and the money to fund the next project.
Chris, I sent you a PM on the '25
Chris - I sent you a PM as well.
