I have the original 5.7L for my 02 TransAm convertible. Car is original, except for the engine. It had that really annoying piston slap issue and since I had a brand new 6.0L sitting in the garage, it was an easy decision. 3 years later and still running fine. So my question is do I hold on to the original engine and maybe someday rebuild it? It ran well, great oil pressure, plenty of power and no noises after it was well warmed up.I know these engines are sleeved, can they be bored out ( if necessary) or just honed? All things being equal, I have room to store the original engine if that is going to make the car more valuable in years to come. If the original engine isnt more than a boat anchor, I can get it to the scrap metal folks.

Id suggest you either save it,
(yes it adds some value when selling the car)
or find someone who is willing to give you a few hundred dollars for it,
theres sure too be some local guy who wants a rebuildable core engine,
he can rebuild for some project.

IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

Thanks Paul. Sounds like it will find a comfy spot in the garage ( heated of course!).

If all it had was the piston slap, it probably doesn't need to be re-bored when it's freshened up. It may be far more than a core. These engines just don't wear much unless mistreated or abused.

I think an 02 LS1 engine still goes for good money. Don't scrap it - save it or sell it.

Unlike a 60s/70s muscle car with an optional original performance engine, I doubt that an 02 will ever fetch extra money for matching numbers.

My first 98Z28 has 390,000+ miles and still runs like a top. Piston slap still there but goes away in under a minute. Bought it with 85,000 miles on it. Think it was 77chevy who stated that it sounded like you had a bucket of bolts in the back seat and to just drive it like you stole it. Words to live by. Just turn the radio up.....

A lesson learned the hard way is not easily forgoten.

It'd have to be an extremely clean low mile car or a very unique car to worry about the original engine. So, I wouldn't be too concerned about it.

I think a good used LS1 can still pull $1500+.

While I do sort of agree with the overall sentiment, you can't really predict future attitudes towards modern cars. Many years ago, a lot of the same things were likely said about cars that are worth a lot today because they're numbers matching.. just a thought.

A lot of classics that *would* be worth a lot more today, but aren't, due to non-matching numbers/non-original engine.. ended up that way because a long time ago someone decided it was just a car and wouldn't matter later. Engine went bad or they wanted more power, just throw another one in and junk/sell the original.

Thanks for all the input. Since I have the room to store it safely, that will be the plan. If I need it, it will be there. If not, my son can deal with it after I head to the big junkyard in the sky, or maybe head to the "warm" one down below.

Well, you're completely taking my post out of context Richard. Numbers matching simply doesn't matter much unless the car is worthy of being a numbers matching car in the future.

Now, I just looked it up and there were apparently 998 Trans Am convertibles made in 2002. So, this car is somewhat rare but that doesn't necessarily mean anything. I have a 68 convertible Beaumont Custom and only 350 of them were made yet numbers matching just doesn't matter with it. Now, if you can tick off the boxes for some rarer options then you are more likely to have a car where numbers matching will matter.

Overall, there are way, way, way more classic cars still around today where them being numbers matching or not still doesn't matter compared to cars where it does. Most are that way because they aren't rare enough that it matters, but then the general condition or how well it survived certainly affects this too.

To note about the possible repair of the engine. You buy slightly oversized pistons for a LS1, meaning you hone the block and fit the new pistons at the proper clearance.

If you have build data readily available ( please dont go on an extensive search) here are the pertinent facts:
1.color 44u not the bright red, more like a maroon
2. all leather interior 522
3. neutral top
4.Y84 (GTA) not sure why or what that is and it has WS9
5. not a WS6 Ram Air car
6. 4l60E transmission
7. positraction and traction control
8. entertainment system option X20

No; I believe you're just taking unnecessary offense to a difference of opinion.

I own a lot of "correct" numbers matching" vehicles, I have been a collector since before working for G.M.

The numbers matching thing has been challenging on a few of them, but more so, the date coding of those few that had incorrect parts installed throughout their lives.

I only have one car that I cannot find the right date code for one part, number is easy, date is so far, impossible. No, I don't "restamp", the numbers are not stamped on, they are added by a numbers roller.

So, numbers matching is essential, date codes go farther for those that need them to match, too.

Shrug... Your comments don't change the fact that people who think their run of the mill nothing special car will be worth gold in the future because it's number matching are still delirious.

I also have a 65 Impala convertible which I still have the original engine in a corner of the shop but it's not because it's the number matching engine but rather because no-one wants a worn out 283 anymore. I also have 3 powerglides in the same corner too, but no-one wants them either.

FYI. I did an internet search ( and we all know if its on the internet, its true!).
2002 non WS6 TransAm convertible, paint code 44u, there were 9 built. How's that for rare. Plan is to clean it up and put in a plastic bubble and wait for it to jump in value to $1 million.
Nope, its fun to drive and it only goes out in good weather and it is stored in a heated garage for the winter. They were built to be driven and that is the plan.

That is a neat thing to be able to claim about the car. It might help with the value someday, but it's hard to tell if a color like you describe will be extra desirable in the future. Keep doing as you said by driving it and enjoying it. It's really a great car to go cruising in on a nice sunny day.

Overall I'd expect the WS6 ram air 6-speed manual cars to have the best chance of being desirable in the future. Tick off all the performance options to buy a car with the best chance of being worth a bunch of money some time in the future.

Just a thought. The V-8 engine is getting to be a pretty rare "bird"(pun intended) these days of the dual fool/hybrid type rolling stock coming out of the auto manufacturers.
I would not get rid of the factory engine. Personally, I think that you may be looking at the future "shoebox". Put the 6.0 in and drive it. I would bet money on your car being WAAAAY more valuable in 50 years with the original engine.
I can almost see the "barn find" revelation now. "very rare Trans AM found with original V-8 under a tarp!!!!!" yada-yada-yada.

Keep it!! Your grandkids may go to college on that engine.
