Before I travel 200 miles to see the car, Can a RB fit inside? This a coil spring or leaf sprung rear? I'm not looking to make a street car but rather a rat drag car.I know that anything can be fab'd but looking for a simplier ride.Thanks

I can't help you on the RB, the rear springs are leaf I think.

rear leaf springs. if it were me doing as you want to do, i would ditch the front suspension and original steering box, then put a straight axle in it's place.
a big block would be easy to install then.
we need to see pics !

Front suspension is coil spring. Very similar to my 51 Plymouth's, can;t help on the B/RB question though.

Sure, depends on your fabrication skills. The rear leaf springs are what's referred to as "splayed", the front mounting points are closer together than the rears.

I'm supposed to respect my elders, but its getting harder and harder for me to find one now.

There is enough space under the hood for an RB. You may loose the inner fenders, and probably the fresh air for the heat, neither of which you probably would have left intact anyway.

The front suspension, if its in good shape will support the RB's weight. It is a decent suspension that parts are available for at many auto parts stores and online. Improvements can be had by moving the shock from the upper control arm to a bracket on the frame, kits are available to do this, but its pretty simple. You definitely want a disc brake conversion, several kits are offered. Its cheaper to do a disc brake conversion then it is to rebuild the original brakes, which would be inadequate for a RB powered car.

The rear suspension, if in good condition will support an RB, but I would swap out the usually open rear axle for something a little bigger, with a sure grip, and much more modern,. The original brakes and rear drum setup is poor design, and the axle flanges are keyed to the axles and probably wouldn't hold up to an RB with traction, which the open diff probably couldn't supply anyway.

You want to make sure the car your looking at has a good frame. They tend to rust out in the lower part of the front cross member, and on the frame rails in front of and behind the leaf spring mounting points. If the frame is not rusted beyond repair and is not bent, they are plenty tough enough for an RB.

It will be required for you to post up pictures and keep us informed about your build. Gene

Thanks for the info of the K rust issues. That's going to be my main concern when I see it tomorrow.

I am sure the bb or RB will fit as I had for years a 1956 Plymouth Belvedere . with a stroked 440...I sold it 2 years ago to a guy in Tennessee Have many pics but can't send them in my new PC without my grand son to show me how..I at first had the original K frame ,then I installed complete K frame from a Chrysler 5th ave....The P/S was the only hang up....the exhaust had to be worked a lot..Many pics around Moparts including Owners pics I think page 3..White with gold trim..car ran 11.38 with no good traction..1.77 60 foot Good luck Larry

The Dakota front clip swap is popular in the '55-'56.
