Which Corvette model got a different engine one year after introduction?

1996 LT4 engine was a one year production. It came in all 6 spd manual cars. The LT4 featured different heads, an intake with shorter runners, higher compression, and a larger cam with 1:6/1 roller rockers.

Are you saying that the LT4 was a one year motor and only in 1996, or the LT4 of 96 was different then the LT4 of 97-98?

The LT4 was a one year production, and only available in the Corvette in 1996. They made 1000 specially vin'd "Grand Sport" editions in Admiral Blue with a white stripe and red hash marks, all LT4 equipped. There were somewhere in the range of 8000 regular production units equipped with the LT4 engine. The LT4 was only available with the manual transmission, and manual transmission was only mated to the LT4. In other words you could not get the regular LT1 with a 6 spd.

The 100 '97 Camaros and the 25 Trans Ams equipped with the LT4 were cars that used the remaining stock of the LT4. These engines and cars were sent to SLP, who did the conversions. These cars did not roll off the assembly line with the LT4. '97 was the first year of the LS1 in the Corvette, and was put into the Camaro in '98.

The C4 came out in 1984, so that isn't what I'm asking.

Read your question a little more closely, sorry about that. However the C4 Corvette is the answer to the question. The 1984 C4 Corvette was introduced with the L82 Crossfire injection, which carried over from the 1982 model. In 1985, GM introduced the L98 TPI in the Corvette.

Ok, so my point is the likelyhood of the Grand Sport getting some new engine, that it will share with the Z/28, next year is slim to none.

Our only hope is GM decides to give the Z/28 it's own performance engine, which has only happened once as well.

I certainly agree with you there. I think the Corvette line up is complete for the 7th Gen. The Grand Sport is as it's going to be. LT1 with the Z06 body. Similar to the C6 model, which was a huge success for them.

The Z/28 is a much more difficult guess. I really don't see them coming out with a special engine for the Z/28 all to it's own. As much as we'd like to see either a bigger N/A engine like the LS7 was, or even a head cam LT1, I just don't see it happening. If they were going to do an LT5 or something like that, they would've introduced it in the GS and then shared it with the Z/28, not the other way around.

If they even make a Z/28, which I have my doubts, it will have to be a suspension focused car. They are going to either put the LT4 in it, with some magnificent suspension/aero/tire package and price it a few grand less than the Z06. Or, and I hope they don't, are going to use it to showcase smaller engine technology, and put the TT V6 in it, and I only see this as possibility as they are putting the 1LE package on V6 cars.

But, it's all anybody's guess at this point. They might very well surprise us all. But if they even build it at all, I will be surprised.

If they can only go with the LT4 or LT1, then they might as well not build a Z/28. I wouldn't want the Z/28 to end up like the Z06 and only good for a lap or two, no matter how fast that lap is.

I don't see any reason to build a Z28 with the base LT1 wouldn't make no sense at all. Needs to be a "special engine" like a hopped up LT1 or a new LT* around 540-550hp. Just don't see them putting in the LT4.

Exactly, which is why I have my doubts about there even being another Z/28. I don't think they could have sold the Gen 5 Z/28 to the bean counters if it weren't for needing to find a home for the LS7's collecting dust in the parts bin.

If I were GM, and wanted to keep the nameplate in the market, perhaps making it an RPO addition to the 1LE would be the way to do it. By adding DSSV, CC brakes, and weight reduction?

Or perhaps by creating the chassis with these items and letting the buyer choose either the LT1 or the LT4? But even then, other than adding DSSV, it would be either a stripped down 1LE or ZL1, which would lead to the same sales problem the former Z/28 had.

The one ray of hope for the Z/28 is that it wouldn't be a whole lot for them to do a simple head and cam package for the LT1. The only thing would be making meet all the EPA and CAFE targets they need to hit. History shows us that the LS6 program was a winner, and it was basically the same situation. But I think for it to be successful, as in sales and ROI, they would have to make the Z/28 a fully optioned car with upgraded suspension and aero.

We have less than 3 weeks until the Camaro 50th anniversary and I have a feeling whatever the car is with all the aero will be there.

Yup. 50th includes the Z/28, it was there in '67.
