OK, I'll search for that;

I'm actually interested in TBI since reading the Megasquirt site.  Doesn't look all that hard using GM parts and fully programmable control box.  I believe it could be put together quite reasonably using Ebay or JY parts.  For that matter, you can probably buy them reconditioned/new at Kragen's/Autozone/Advance Auto easily and within budget as well.

I'd stay with stock, just maybe clean them up some; If I spend the money on aluminum heads, they'd go on that 390 of mine, not this project.

Yes, 304's are easier for a number of reasons, but good 290's pop up from time to time, including one I know about now from a club member, so just thought I'd throw that out there, plus being a little bit smaller engine, you might get a little bit better mileage, altho I'm sure not enough to justify making big changes.

Don't know enough about LPG; I guess you could run multifuel with TBI and a controller as you could dial in different states of tune depending on the fuel you're using, but, is LPG that much cheaper to run?  Is there anyone running it on a converted vehicle that can answer that?  We have dual-fuel vehicles here at work (gas + LPG)that you switch back and forth with a switch on the dashboard, but I don't pay the bills on those, plus no one that I know really keeps track of economy as there's multiple driver's for any vehicle in our shop.  It seems to me that the tanks are fairly big for what you get.  I mean, we have them in the bed of pickup trucks up near the cab, and it seems that the range on the tank isn't all that great for the size, know what I mean?

I also took Bruce Hevner's advice and started reading up on Ethanol.  That's interesting as well, plus, if you could get the raw materials easy/cheap enough, you could "brew your own" with a permit from the Fed Gov't from what I read.  There's lots I DON'T know about all this, but it is food for thought!

It does have the storage area, but I'd really have to think about that.  I'm leaning more toward the '65 440 for this project.  It's lighter, has a trunk IF I wanted to multifuel it, plus I really like the wagon the way it is for the most part, altho I'm not a strict stock person.

Anyone got a complete 304? I have a 360 I'd trade.  It would be hard for me to sneak in another engine past Mama, but if one left, and one took it's place, well, that's different!
