I've got a pretty good grasp on the differences ... I was trying to say that the average person doesn't.

Even the above average person sometimes doesn't. Starting in the 80s, single/dual headlights were often a matter of which model it was, cheapies had two headlights, more expensive versions (silverado) had 4My fabulous web page

Any plans for this? Or are you just going to cruise/use it?
I LOVED my '95 350 TBI truck, but always hated how gutless it was for the fuel it used.
Just a small cam and a GOOD tuning will make a night and day difference!
The main issue is the speed density system is so fussy with changes to intake vacuum signal (like swapping the cam)
There are a couple of ways to work through this.
You can build an ALDL cable and datalog with winALDL. (hell you should do that anyway...its FREE!) http://winaldl.joby.se/
Then you can send your data logs to Brian at http://www.tbichips.com/ to have a new PROM burned. With some effort you can get pretty close. (My truck ran GOOD until 4000rpm, but I'll cover that in a minute)
The better option is embedded lockers from http://www.dynamicefi.com/
With this you will truly control the whole system and can tune on the fly and use a wideband! Its not cheap, ($400)but there have been group buys and used ones pop up from time to time.
The other issue is low fuel pressure. TBI systems run on 11-13 psi and there is nothing wrong with that. The issue is the injectors run out of pulse width early and your hopped up TBI motor will run out of fuel just as the fun really starts. (4000rpm)
The solution is very simple. A factory replacement Fbody TPI should bolt right to your fuel pickup and after making your TBI fuel pressure regulator adjustable, give a nice 17psi. With the higher pressure, the injector pulse width can be reduced across the board and give you more "room" at the higher RPM's.
This is a good "budget" small block TBI build.
This is a higher budget, but still simple, big block TBI build.

Thanks for all the great comments. I don't plan on any mechanical projects as everything seems to be in good working order. And I don't really feel the need to tear into a good running 350 to make it marginally better. I think I'll focus on cleaning it up well and maybe sprucing up the interior a bit more. Maybe as far as swapping in a late model interior. There's plenty of daydreaming to be had on the 67-72chevy trucks forum. I think the shortened crew cabs (cut 14" of frame out and swap on a 6' bed) look great, but don't really think I'll go there.

I bought my 77 chevy flat bed dualie with a flat cam.. Put in a Blue Racer/Wolverine RV2 cam, Performer intake and 600 Holley, and headers.. Really woke it up.. 16 mpg.. Could keep up with and beat big blocks.. Power from 800 rpms to 5000... That little 350 was a real worker!
