What engine would you build for a Ramcharger?

I would stick the most cubic inch in it you can afford personally.....

However my 85 W150 had a 340 (9:1) in it with stock 915 heads. Roller Rockers, 268 RV cam, headers, performer RPM, stock converter and 3:21 gears. 1406 Eddy. I got around 14 on the highway and whatever in the city. It wasn't a killer piece but it did a fair amount of towing for me and never missed a blink.

If I did it over again the truck would have gotten a motor with a slanted dizzy lol.... But I like cubes in a older truck....
