chrysler spitfire I6?

A guy I know has a few of these laying around in early 50's chrysler's. they all run. Anything to them? Are they anything special?

I don't understand your question, Chrysler used those engines for many years.

 

I don't know anything about them. I just want to know are they good engines? Are they Hot? Are they worth pulling out of the cars? Would they make good hot rod engines? Are there any performane parts made for them?

All I know is they are flat head inline sixs and they look cool.

Thats all.

 

i think they,re a inch longer then the plymouths and dodges,

 

They're just standard Chrysler big car engines. Not particularly valueable, nobody's out hunting for them. They were quite reliable and Chrysler used them for many years, however I don't think they have much resale value, unless they're good runners and you can find someone looking for a stock replacement engine. There are a few hop up parts for them out there but they can sometimes be expensive since they're rare.

 

Good motors, lots of forklifts, boats, airport tugs, other machine apps used 'em. Respond real well to milling of head for 8:1 or better CR.

Full pressure oiling, insert bearings; not a powerhouse. You can still get parts
but shouldn't need to do so all the time.

Don't ask my dad how they run vs 59AB ford; he'll go on for 10 min about his Royal 6 powered 37 Dodge... suffice it to say a number of stock fords saw some dodge taillight in southern california. And his was a stock chrysler engine.

too bad you are in GA, I happen to be looking for something like you have but shipping across country would probably blow my budget apart. There has been interest in the flathead sixes on this board try searching the older posts have had some good info on possible performance upgrades.

25 inches long, dodge and plymouth were 23.5. Long stroke engines of 251 or 265 Cubes depending on stroke (same bore) 105 to 115 HP depending on year, lots of torque. Usually conected to a semi automatic dual range 2 speed ******. Will run forever. Some speed parts available, couple of guys make split intakes and exhaust manifolds. As for interesting looking in a rod........

 

Speed parts dont seem to be as common as the Dodge/Plymouth flatheads, but ther are avalible. It's not overly difficult to make your own intake and exhaust either. Plus the head says "Firepower" on it, and that's just plain neat

 

thanks for the info guys. thats what i was looking for.

Any inline flathead is a cool looking motor. If I had one, I'd be looking to build an open wheeled roadster or modified with no hood.

So is the chrysler six the same block as was used in the bigger dodge trucks ? 25" vs 23.5"

i'm building one (plymouth flat six) with help from moparsled.
its going in my roadster pickup.

 

I'm gonna want to see pics.

yep, also all canadian made cars and trucks used the 25 inch.

 

The Spitfire logo was just a marketing gimmick used back in the day. But looks cool stamped on the head. Im building a 237 'big block' (same block as 251 or 265) that will end up being 268 cubic inches when im said and done. Raised compression ratio without milling head or block. Its being built with off-t******lf parts and shouldnt be very expensive at all. Its going in my '29 Dodge Brothers truck. I personally love the flathead sixes. Tons of torque.

 

put one in a ha/gr and go to town on the fords!
