Snowman,
A lot of folks here just like to run the old iron, I did started out with a hot 292 but was not happy with it so I changed to a 4200.
If someone was to install a 4200 into a post '66 gm chassis its not that hard.
I used a '78 nova clip in my '51 gmc.
Changes needed are:
1) rear sump oil pan (now avaialble).
2) fabricated mounts but I think a LS engine mount kit is very close.
3) transmission swap - easiest is to keep the OEM 4l60e
4) install the GM electronics - this has been done many times now and the kinks have been worked out.
5) shorten the driveshaft.
6) install the OEM electronic gas pedal.
7) exhaust, and cooling hook ups.
Is it more work - yes - hard to do - depends on your skill set.
In my opinion the 4200 runs rings around the old iron. 2-3 x the HP 1/2 the fuel consumption.
