318 or 383 What to do...

Man I hate this, I was plan on dropping in my rebuilt 318 4 bbl in my Duster.It would still run pretty good.And I have a 4 speed to put behind it.I have a new set of Doug's,motor mounts,and 2 1/4 exhaust kit for it.

But lately I have been thinking of dropping in my rebulit 383 into Duster.It is around 400-425 Hp and would be alot of fun.I would run a 727 just to make things easier.And I have a new set of headman elites I could use.I built the engine myself and have some money in it and I hate to see it just sit in the corner.
I can only afford one toy these days.So do I want the 318 4 speed that will still move pretty good and be decent on gas.Or do I want the hear the rumble of my 383 and the fun of a big block in a smaller car. Man I hate this but I am really leaning toward the 383 and selling off the Dougs and motor mounts.I think I will keep the 4 speed for now. Hmmmm......What to do...I know the slant 6 is going bye bye soon!
