This is a three step plan.

First is a 350 or 383 engine built for LOW RPM operation and MAX torque.

Second using a 80's TPI system.

Third adding a second overdrive transmission behind the stock 4 Speed automatic transmission.
You've gotten some good advice. Look for the Caprice wagon thread https://ecomodder.com/forum/showthre...mpg-33961.html. It has a good summary in the first post.

I assume you're attached to the vehicle. My van had a 1600cc flat four, 3/4 ton axles, with sway bars and suspension mods. It got 30 mpg, topped out at 85 and would top the Coast Range at 75, empty.

My idea of a super MPG van would be a Previa with an EV conversion.
