LT1 and LT4 differences
My neighbor bought a 96 that was sold to him as an LT4. As I looked at the engine it appers to me (with my limited knowlege) to be an LT1. I was convinced he had been misled in the deal. However I came across a thread here which showed a pic of an engine that was supposedly an LT4.
Now I am wondering if maybe in fact it is an LT4. The engine I was thinking was an LT4 I now see is actually an LT5. So, my question is do the LT4 and LT1 appear to be similar? How can he be sure what engine he really has?
You know what they say, The only dumb question is one not asked! LOL
Thanks for clueing me in!

This is the noob way to find out
96 LT1: automatics
96 LT4: 6 speeds
LT4 has a red intake
Thats about it.

If he paid for an LT4, but got an LT1 I'd be pissed. Not knocking the LT1, both are great engines, but the LT4 (modified version of the LT1), for obvious reasons, tend to be priced a bit higher on the market.

You don't have to open the hood on a 96' to find out if it is an LT-1 or an LT-4. Look inside, if it has an automatic it is an LT-1 If it has a 6 speed LT-4 and finally to double check, the tach on an LT-1 goes to 6,000rpm and 8,000 on an LT-4.

And the final "proof" to determine a factory LT4 car.
Check the 8th character of the VIN. P=LT1, 5=LT4
Remember, people have swapped the 8k tach and painted their intake red on LT1 cars.
And there is at least one LT4 car out there that has been converted to an automatic.

Transplanted LT4 with higher stall converter. Other than that stock.

And now you know why to check the VIN. It's the only way to tell a true factory LT4.
Same thing goes for the Grand Sport. They have a unique VIN separate from all other '96 Corvettes.
That unique VIN is the main reason a GS can command a higher price than your normal LT4 cars, since there really isn't any other difference between them.

Didn't want to stir any controversy! I have checked all of the above and confirmed it is an LT1, and yes he was told it was an LT4 at the time of sale, but he doesn't seem to be to concerned about it!! 
Thanks to all who responded with all the great info!!

Tell him that I said that because he bought a LT4 he paid more. The ZF6 holds more value in the KBB. I would go back and get me at least $700

Well, it may have the "LT4 Hotcam Kit" done to it. so perhaps the seller thought himself justified in calling the LT4.
I mean, other than the intake, injectors, rockers, springs, valves, heads, crank, timing gear, compression ratio, etc. it's the same motor, right? I mean they use the same block.
