help someone make up my mind????

[slt0066]

I found a guy that wants to sell his 72 longbed fleetside for $3000, or trade for a 4cyl car
heres were i come in I have a 94 honda accord runs great no issues ...........
i dont think i could get $3000 for my car if i tried to sell it
gas prices are going crazy and this truck would have to be my daily driver.
what can i expect for milage with the 350/350 combo?

Ive got a 72 swb that im in the process of restoring but I'm starting to jones for a truck to drive.....
what do you guys think should i trade for it or keep the gas sipper and focus on finishing the swb.....
