TPI or TBI ??
How can you tell the difference between the two by looking in the engine compartment ?

ok
Throttle Body Injection will have an old style air cleaner housing on top. If you remove it to the untrained eye it appears that you have a carb.
Tuned Port Injection has an aluminum manifold with curved tubes(runners) going downward.
Here's a picture of what a Throttle Body Injected engine with an open element air cleaner looks like

No, you don't have a Vortec engine. They didn't come in a Camaro, nor as a 305 like you have there.

nope
get the casting numbers from the block (google how if you don't know) and stop hoping for it to be something it's not
you are going to find that you have a dog and it's not worth tossing parts at it trying to make it a performer. It was a victim of the low performace era. You can't will the engine to be more than it is.

I'm not "willing" anything thank you. Just trying to figure out exactly what I have here. I will be looking up the vin # to find out for sure. And as far as throwing parts, all the hardtops body's are the same, it's gonna be faster than a z anyway when I'm done so technically it won't be a z anyway. In other words, care not.

I have a Rs TBI setup under the hood, this could mean badge swap, or some one blew a motor and transplanted Rs guts into a z28 body. The vin# will tell me the truth. I can't wait to find out.

please read what's being posted
get the casting #'s off of the block or accept that you have an LO3
the LO3 is a reliable engine. It's just not a performance engine but that's the way it was during that era.
Yes, it's a Camaro but you're talking an era of Chrysler K cars (Plymouth Reliant and Dodge Aries) as well as Chevy Citations. The big engine in the S10 Blazers were the earth shattering 2.8 v6 with 120HP and people towed with that rig.
