Assuming you eliminate as much variance as possible it comes down to a bore and stroke difference. Two variables; one if you just consider displacement.

If rod length made as much difference as you think it does there would be ong rods in everything, but it doesn't. Sure it makes a slight difference (and even that is often misunderstood) but the best thing you could do is a good rebuild of the engine and an OD trans.

Do you know what mileage a NEW 3/4 ton work van gets when its loaded down. There is no chance you will beat that with an SBC, you'll be lucky to come within 80% of that. If you want to "march to your own drum" and ignore what people are telling you you can expect 40% of that.
