I was already expecting these things to be difficult
Let's focus on the engine first
you need to check casting numbers of the block and the cylinder heads.
To get the cylinder head numbers you need to remove a valve cover and the numbers are stamped into the head
for the block, the number is on the rear so you'll need a mechanics mirror and light. There is also a number on the passenger side front but the rear number tells all
you can then search this site as there are many threads on the secret decoder ring for converting casting numbers to useful information
none of that will tell you if the engine is bored, stroked, the heads had work done etc.
It's just basic stuff but good to know
as for gear ratio, put the rear on jack stands, put the car in neutral, put a chalk mark on the drive shaft and also on a tire, have a buddy slowly rotate a tire counterclockwise 1 rotation and make note of how many rotations the driveshaft made. That will give you an approximation of #:1 ratio
If the shaft rotated almost 3 times then you probably have 2.73:1 gears
Fast and Furious was good for bringing passion back for cars but there is a ton of misinformation and nonsense in those movies. Let's look at FI (forced induction) for example. Think of what those 2 words mean? Gen 1 small block chevy's do not flow as well as modern Mustangs which you can get bolt on FI or the 4 valve per cylinder ricers.
Think again about what FI does. It forces more air into your engine. Since you never ever wanto to run real lean what do you need to mix with all of that extra air? Why you need to add more fuel. Trying to run a turbo wit a carb engine can be done but is very tricky. It's easier to use a supercharger because the boost is relatively the same at all rpm's
So, you need to be able to add more fuel to that extra air. Next, you need to be able to take advantage of that mixture and also, since you are forcing more volume into the same space you are adding a lot more stress. You're also creating more power which means more stress on the rotating assembly and moving parts. But, i'm getting ahead of myself.
You need to be able to spray more fuel namely larger fuel injectors, higher volume fuel pump and larger fuel lines. You then need to flow better so good cylinder heads are in order. You also then need to get rid of the spent gases so better exhaust is needed.
I encourage you to do some reading about forced induction and not on forums because there is way too much misinformation (maybe from me too)
Heck, I read on a forum that you can buy a good LS1 and swap it into a 3rd gen for under $2k
Personally, i would not put a used motor that i knew nothing about into any of my vehicles. So, if I buy a used engine then a $1300- $1500 basic rebuild is in store. That is above and beyond the purchase price of the engine. That price is for a gen 1 small block. The price to rebuild an LT1 or LS1 is much more. And those aren't performance rebuilds.
So, do some reading, continue to monitor forums and ask questions. And with respect to street legal. You can make a high 8 second car (1/4 mile) street legal. it might not be a pleasant daily driver but it would be street legal.
