'48 New Yorker conversion to Hemi


Where can info be located on conversion of '48 New Yorker from Straight 8 to a Hemi? Which Hemi/Trans combination would be easiest/best?

www.jalopyjournal.com then click on the HAMB & put 46-8 Plymouth in "search" lots of threads on reengining thev 46-8 Mopars & check out the "Hemi Tech Index".

It would be easier with a rear sump compatable clip swap from something like a Camaro, Cutlass or Chevelle. Would be an easier fit than with the OEM front clip. DeSoto & Chrysler hemis are rear sump(392 can be converted to rear sump). The DeSotos are smaller physically so easier to drop in. I'd recommend using a 727 A/T tranny with a floor shifter. You'd also need a modern 8 3/4, 9" or 12 bolt rear axle. If you want an A/T I'd say the 54-56 Chrs are the way to go. Avoid the 51-4 long tail 331s unless you want a stick.

You'll probably have to trim the inner fenders. If you have the OEM upper engine mounts you can make/have made lower mounts for your frame, or use Chassis Engineering uppers. A tranny crossover with mount is simple & cheap to make.
