Re: [AMC-list] Nash Truck

[Frank Swygert <farna@xxxxxxx>]

The small Nash/Rambler/AMC sixes are a totally different design than the earlier big Nash sixes or the later bigger AMC sixes. No parts, not even the bell housing bolt pattern, interchanges. All the 40-65 L-head parts interchange, and many of the 196 OHV parts interchange with the L-heads, but that's it. Only the rods, crank, and timing set of the aluminum block 196 OHV interchange with the iron OHV (and the L-heads). 

I'd go with a later model AMC six swap if the old engine wasn't rebuildable and/or I wanted to update the drivetrain for actual use. The transmission from the newer engine would likely have to be used also, or an adapter cobbled up. The original rear axle could be kept, just have to have a driveshaft made up.

If you're concerned about being correct, you could bolt in a 258 from 
the same year Ambassador. Very robust engine... just like the ones 
made 40 years later. Or a modern EFI 4.0...
