I just wanted to know what is the best setup for fuel economy that can still pull a boat without issue. This truck will be driven long distances in the summer as everything up here in my area of Canada is spread apart. So I guess the marine carb idea is a bust, just wondered if it was worth my time because I had a few different carbs from different small block engines. So what do I need for the best fuel economy without losing towing capabilities?

Your best bet would be to do this...Head work...Have lumps installed..and then convert over to a 1.84 intake valve leaving the exhaust valves stock. Then have a 500 edelbrock installed on a clifford intake and a set of headers with an HEI...that'll give you a little more power and torque and mileage...the original cam is setup for this type of towing so you'll be fine there.. also converting over to an over drive tanny would help...in your case..maybe an NV4500...its a 5 speed that still has the low 1st gear so yer not burning up yer clutch when loaded. But don't expect to get super good mileage when towing...and that goes with any engine.
