I can’t help you with the value of the transmission ... but the value of a running 302 is all over the board depending on the seller. I have picked up short block 302’s for 300.00, rebuilt military surplus and crated 302’s for 600.00 and paid about 900.00 for a rougher 302. Yet, some vendors will list them from 1200-1500.00-2200.00 give or take.
The rebuilt military 270’s and 302’s I have seen typically come with metal tags on them that specify bearing and piston sizes, rebuild date, and serial number. These are usually fastened to the engine block.
Lots of opinions here about dual exhaust, intakes, multiple carbs etc... but if it was me - I tend to stay with stock manifolds and carbs on these, just as they were designed for...unless you want to take the 1 ton to Bonneville salt flats and modify it for that use but I like old school hot rods and wish I could install a modified 302 into a model A roadster. 270 and 302’s are fine engines.
