Keep the 292...............I have had both Inliners and V's and IMO the Inliners are more reliable power plants for work, not to mention they have the power where you need it, not up high in the RPM range that you can't reach unless you have alot of gears like a small block.
We have a little 250 in a C-10 and it will blow the doors off me in my C-20 with a 350 going up a grade with a Kicker Hay wagon............I am in 2nd with it screamin, while he can run high gear. He can pull two in second...........We'll I never even tried it because I'd probably have to get out and push

They don't weigh anything, but the high sides drag in the wind like a sail making them missery to pull anywhere about 20 mph.
IMO you better send the 283 with the rest of the scrap iron to china

I'd put in a 305 before that
