Yes they are the same and different??? I know in can be confusing. The 4010 404 is not a good thought, they don't have as many engine side frame holes as the newer ones, as the progressed they got better, the 4620 blocks are the same bolt patterns as your 7020, they have a bit different shape near the lower left side to allow for 4620 steering lines to pass through, the higher HP engines have bigger injection systems, inter-coolers and turbos., the newer 466 engines will work good too, with the exception of the latter style engines (50 sereis0 they have a larger side frame bolt and pattern. for your application a 7720 combine engine would be a good choice, 466 cid,turbo, and will deliver 175 HP all day long.
