I recently acquired a TBI 350 and 700r4 setup. I am trying to figure exactly what it came out of. The guy I got it from had no clue. So I cleaned up some of the motor and the block # is 14093638 (86-94 Block). Once I had that I cleaned up the front of the block's pad on the passenger side and came up with V0205TDF, I understand the date part of it, but when I go to pull up the suffix "TDF" all I come up with is 1980 SBC, which I know it isn't. ?? So this is where I need help. The block is a 2 block main, heads #1410293 (swirl port). Any help would be great.

Ideally I would like to do a basic rebuild as a the car it will be going in is more of a cruiser, however I want switch to a carb set up and possible look at putting a mild roller cam in it as well to give it some "umph".

 

Don't worry about the codes. Even if you found out what year, model, color, and all the options the car it came in had, just think, what difference would it make? What would you do differently depending on what car it used to be in? Exactly.

You already know it's a L05. There's only ONE kind of those, and you have it. Doesn't matter what sheet metal it used to wrapped in; all it is now, is a L05, same as all the others. Cast iron is well and widely known to have a very short memory: you may rest assured, it has already forgot its previous sheet metal, and will be just as happy in yours, as it was in whatever wrappings it originally had.

Just remember, it's a L05. Most likely doesn't have a roller cam although most likely has all the provisions for it, up to some random degree of completion. Has super crappy heads so there's a HARD upper limit to what it'll do. Apart from that, work with what you've got and don't try to turn it into something it can't be, and it'll stand a better chance of satisfying you.
