How do I know what Generation my Z is?
I keep seeing 3rd and 4th gerneration of LT1. All I know is I have the 1994 Camaro Z28 that was sold w/ the governer chip and reads 115 on the speedometer. I believe that the generation only deals w/ the engine so I posed this question. Also off topic can someone tell me wht other models are compatable w/ interion panels (door) for a 94 z28.
Much thanks..

You have a 4th generation Camaro. I have never seen the LT engine model referred to in the manner you mentioned. It is considered a Generation II engine from GM. All LT blocks, essentially were the same (no flame on the corvette 4 bolt mains, ok guys).
There was mutliple computers that ran the LT1. Your 94 uses an OBD I PCM and does not use a "chip". The PCM can be reprogrammed directly in the car. With software, that govenor can be taken out very easily. That is the way they came from the factory.

Its not split up. How many engines & variations were in the 1st, 2nd & 3rd gens? Who refers to things in half generations seriously?

I think the confusion comes from the fact that we also count generations of the small block V8. The Gen1 V8 came out in 1953 in an Oldsmobile and lasted until 1992.
The LT1 came out in 1992 (in the Corvette) and was the first Gen2 V8. The LT4 was another Gen2. The LT5 is an anomaly that has nothing in common with any GM engine.
The LS1 came out in 1997 (again in the Corvette) and was the first Gen3 V8. LS6 (from the C5 Z06 and original CTS-V) was also Gen3.
The LS2 came out in 2005 (GTO, CTS-V, and C6 Corvette) and was the first Gen4 V8. The LS7, LS3, LS9, and LSA are all members of this generation.
A rumored fifth generation V8 is supposedly in development (although possibly on hold while GM works out the bankruptcy and restructuring stuff).

Model generations are normally based on body style (minor changes don't count).
Engine generations are totally another thing.
Truly. It's either a generation or it's not.

The 1953 Oldsmobile V8 engine was not a Gen 1 SBC (Small Block Chevy). The Gen 1 SBC originated with the 1955 Chevy (aka "Shoebox" ). It was used right up into the late 1990's in the GM trucks.

And why they divide up the LS motors is insane. They are both designed on the same basic structure. If I'm not mistaken isn't it only a top end difference? If I'm right, why classify them as two separate generations of engines? I understand the classic SBC to LT, but they didn't do a Gen change when they started using centerbolt v/c's and one-piece rear main seals. The block is essentially unchanged, then why would we do it for an engine that has only had new heads and intake put onto it......
Just a senseless rant I suppose....

Well I do for one! Only I refer to them as 4th Gen. A & 4th Gen. B cars. Because not only did they change the front, they had different engines too.

Actually there were so many changes in '69 it probably should have been called a 2nd Gen.
Besides you and I both know that the engine/trans. has nothing to do with the term, "Generation," as applied to Corvettes and Camaros.
I wasn't being serious!!!
