I listed this for sale on marketplace in hopes someone could use it. Pricing is flexable. Thanks Marketplace - Chrysler PowerFlite Transmission | Facebook

Thank you kindly. This was exactly what i was looking for lol. I have a few ideas on which direction I want to go, but nothing set in stone. Once i get my hands on a block i’ll have a more concrete plan. I try not to get to far ahead of myself. Id like to get to the 200hp mark if at all possible. I will definitely be in touch.

I appreciate all the info guys. Yeah, basically im really just looking for a block that i can go through and wring as much power as i can out if it, reliably. When were the blocks with full flow oil filters produced? Towards the end of production in the mid 50’s, or did the start earlier? A 251 wouldn’t be a deal breaker if it’s a bit easier to find. Do these engines have the room to bore them out? Just kind of thinking out loud.

Im looking for the best as far as what woll make the best reliable horsepower in a 25” block. I know there isn’t as much aftermarket support when it comes to these engines, but i want to keep it in the same motor family that came factory with a desoto airflow. I appreciate all the for sale ads, but im not ready to purchase yet. Just doing homework at the moment. thanks

I appreciate all the info. My next trip to the junkyard i will keep my eyes peeled. Im sure that somewhere in there is a 265, between combines, generators, forklifts, power wagons and 53-54 desotos/Chryslers. They have an old car section at the back that will hopefully prove fruitful.

That sounds like a pretty cool project. I have a junkyard that I frequent that does have some farm equipment. Do the industrial engines interchange with the automotive engines? If so, that definitely could be an option. I was unable to find said wiki page for make/model cross reference for industrial/truck applications. When i’m poking around the junkyard, is there a way to tell a mopar flathead apart from other flathead sixes when looking at things like combines, forklifts and generators? As far as truck flatheads, they probably did see a pretty hard life, but the trucks seem to be a little more common at least around these parts (eastern pa). If they are rebuildable, I'm game.

I can appreciate everyone’s opinion, but i’m not building a car for you guys....Im building a car for me. To me, the other mopars of the era are cool, but they don’t reel me in like the airflow does. America’s version of the beautiful teardrop coupes from Europe. I don’t plan on making a street rod...like i said, im look to make a factory style special of sorts. Improved power, handling and braking without using post 1950’s technology. Im not looking to invest my money in a car. Imnot worried about potential value when im done building it. I am looking to build a car that i have been dreaming about for years. So, any other things I should be looking for in my 265 hunt? Anyone have any info on the availability of these motors in trucks?

I did see that one on ebay. Its like a splinter in my brain lol. If i had the extra cash right now it would be mine. Saving for my first house is priority #1 at the moment. Unfortunately, yes airflow parts are quite rare, but im not concerned about 100% originality. As long as it period correct, im cool with that. Im looking to make sort of like a factory style high performance special. Supercharged 265, winters quick change rear end, tube shocks, heavy duty springs....I figured I would start with the the best engine in the flathead 6 mopar family for my future project.

See the funny thing is that I don’t have an airflow yet. Im gathering info based on the direction i want to take the build when im in a position to buy one.

Capt den, From what I could find, the desoto airflow had a 25” 242ci from the factory. I read that just about all of the 25” should bolt up, not taking into account the transmission bolt pattern. I very well could be wrong, but that’s what I could find. thanks

Awesome, thank you. You wouldn’t happen to know what years and what model chryslers came with the 265 spitfire? Are there any specific block marking/stampings that differentiates the 265 spitfire from 251s or earlier 242s beside the spitfire head? I apologize for asking so many questions. I will be looking to hunt one down in the near future and I just want to make sure i get what im looking for. Thanks

Hi everyone, I’ve been wandering the web looking for information on flathead mopar 6 cylinders, specifically the larger 25” block. Is there any specific iteration of the 265 that is considered the best as far as durability and making horsepower is concerned? Im having a bit of a hard time finding specific info on these engines. Any help or a point in the right direction would be greatly appreciated. Thanks
