Power ideas for 29 Desoto???

[26Troadster]

i would go the small block (la) and either a 904 (most common) or a 727 (truck/van/big car) auto trans. the slant 6 will take a lot of room. you may be able to fit the la a lot easier. go to your local yards and see what they have, might be a duster/dart/demon or a truck/van setting there with the complete setup. that way you will have all the linkages which the mopar trans has to have. my choice on a inline 6 would be a amc 232/258 or 4.0, but the inlines may be to long to fit the stock frame. if the car came with a 4 or 6 and they went like a dodge it may have had a continental red seal, but i'm not sure.

ps i went and looked and it appears they used the red seal 6 in their cars.

As far as mating to the 9 inch that's no concern you just need to get the right u joints.

My Desoto I have came with the Silverdome Flat 6. It's all there with matching numbers but I haven't looked deep to see if its salvageable. It would be cool to use the original motor but don't know if I would ever get anywhere with its whopping 70hp... 76 with the "red head" aluminum head.

they used the red seal in airplanes with around 65 horsepower. we had a navy towmotor forklift that had the airplane motor, 18 or 19 years ago the rebuild kit was over 1200.00 dollars. i just saw it was the flat 6 and figured it was a red seal. nothing says cool like the old flatties.

Yup, that. and they are generally pretty decent on gas mileage.
Zoomies seem cool but I'd compromise that if the family is going. They will soon tire of the loudness and fumes.

How about a rear to back that up? I'm wanting, if I can find one, to put a 442 Olds w-30 rear with the w-27 cover... Just to be cool and different. Would his be a paint for parts and adaptability or should I stick with a mopar 8 1/2" or 8 3/4" rear?

Not hard to adapt any rear to any vehicle.
I'd say the price of one will be astronomical.
You could just use a Chevy 10 or 12 bolt rear and put a W27 cover on it.

A RWD dodge pickup with 360 magnum engine and 518 overdrive trans. are in all the salvage yards. You can use the EFI or go carbureted.

If you get up over 400 HP with a cam, head work, intake, carb, and distributer.
Just a decent little small block that shouldn't break the bank.
Maybe.

Old Iron... The actual w27 is astronomical ($8,000- $10,000)... I've seen some 70-72 442 w30/31 complete rears for $300-$500. I think the 71 was different for some reason. I did find a w27 cover for the mopar rear... I may go that route and keep it Mopar.

I figured it would be that high. WOW
