The price I'm at right now (if I rebuild the 350, choice "a") is about 1400. I originally was looking at an LS/4l80e swap ... but decided no this pass b/c: I'm short on time (to get the 71 working right), I didnt want to deal with the gas tank (fuel pump), shortening the driveshaft, crossmember, wiring, making sure it all fits (I have factory a/c), etc etc. Besides, I have a 78RS in my other garage that would love to be the mule for an LS swap when I start working on that one For the 383 - a bottom end kit is about a grand, I have to talk to the machine shop how much the labor would run to go this route. So if my 1400 grows to, say, 2000, (wild guessing), it might be worth it. That's what i'm trying to sort out.
