1973 Pontiac Firebird Formula - sell or build value

[Alponcho]

I love early 2nd gen birds. I've done a couple. You might do well selling the car as is. It would be a nice starting point for someone wanting to do their own build without having to worry about paint & interior...maybe low to mid 20s if it's as nice as you say but fairly limited pool of potential buyers. I suspect your best bet from an ROI standpoint, especially if you can do the work yourself, would be to have the 400 rebuilt (maybe stroke it) or find one, and sort out as much as you can. This would give you the biggest pool of potential buyers. An LS-based build like you described could be nice (I just finished a '79 like this), but costs add up, and finding a buyer might be difficult unless you upgraded other things (e.g., brakes, wheels, etc.), and of course that would push the price up even more.
