Re: Thinking about building a rat rod with a 366. Worth it or no?

How to do that, I'm not sure. I think the 366 has a standard bolt pattern, so any Chevy transmission should bolt up. Or add an OD unit instead of the splitter. I'd be tempted to try it. I would definitely try to take advantage of the torque and lightness of your chassis. Ditch the governor if it has one. Don't get too attached to the axles, they may hold you back. If you want a light-duty dually with the HD appearance, find someone with a Dana 70U and highway gears (ie: 3.07 or less if you can find it!). Folks usually want to give those away. And forget trying to rev it and lay tire. It won't be a good setup for that. But you can use the torque wisely and still have fun.
I'm assuming the 366 is like my GMC's 305E V6. Torque down low and not fast by any means. I will say though that with the little mods I did to my V6 it pulls 100% better than before. It'll lay tire rubber no problem at 2000-3000 rpm. lol Have bumped it up to 3K, but nothing higher. Buddy of mine has a propane powered 366 in a school bus.....moves that thing along with no problem.
