A '54 235 is a straight-forward swap that would require almost no modifications, except those needed to support the hop up parts.
The 292 in fully 25% bigger than the 235 (cu. in.) and could make substantially more power.
Where the 235 is basically a bolt-in swap the 292 requires V-8 style mounts and a different bell housing.
I don't understand your statement about using the A833 with the 235 and a 5-speed with the 292. Both motors can readily be adapted to either trans and neither is really a heavy duty transmission.
Easiest swap is the 235. The 292 would be easier than a V-8.
Nice to know can you run a th350 or 700r4 onthe 292 or would i still need the adapter plate like if i was to use my stock 216 and can i run the foot starter with the 292 with or without the auto?
