Re: Mystery LS1
question would not larger injectors cause the ecm pull fuel back?
a friend said I had LS6 injectors, he had just put the larger injectors in his car so I believe him

You indicate:
I had a firebird 2002 owner look at the engine and listen and said they are not the same.
both gm and slp deny it
Since Roush bought SLP in 2013, finding out about specific vehicles has become a bit more difficult. But the founder of SLP, Ed Hamburger, is still available. He now operates HSV (Hamburger Specialty Vehicles). You might want to contact him there, and see if he can shed some light on your search. There were always rumors that the LS6 would be installed on some of the final year 2002 F-Bodies, but all the references I have seen indicate it never happened.

A decent reference on the last years of the LS1 in the F-Body, with regard to part #'s, injector sizes, performance mods:

LS1 - 12564241
LS6 - 12564243
Look at the exhaust manifold side of the head. On top of the rectangular edge that forms the face of the exhaust ports, there should be a three-digit number cast. Either 241, 243 or 799. Go to this eBay listing, and hover the mouse over the photo of the heads. When the photo enlarges, move the mouse down to the bottom of the picture, the head on the right. You will see the "241" location. Appears to be right above a number with the same number of digits you quoted, but not the same number. That may be a production date code.

Re: Mystery LS1
All 2001 and up LS1s, regardless of the car they went in, got the LS6 intake. It was paired with a slightly milder cam, and a +5hp rating relative to the 2000 model. (305->310 for Z28s and Trans Ams; 320->325 for SSes and WS6s, 345->350 for C5s).
It also makes the engine a bit more tractable in the very low RPM range. For example, my 2002 is perfectly happy to loaf along at 40mph in 6th gear, running just 800rpm. The earlier cars will lug if you try that.

Re: Mystery LS1
thanks for all your help all of you
I could not do that stunt 800 rpm in 6th gear at 40 mph it would protest loudly.
any thing below a 1000 it would complain.
my friend who had a transam had headers 3 inch exhaust and a forched air induction, that was not one I seem before fed diretly to a huge 12x14 filter.
I won,t bother asking questions any more for a while
BTW the fuel filter change definetly help the high rpm running.

Re: Mystery LS1
there is a new mystery as it appears not to have no rev limit,
in low gear when having fun the car got away from me, it spun up to 6400 rpm before I caught it . does not the ls1 have a rpm shut off of 6200 rpm?
and at 6400 it was charging for more it did not even try to stop reving

Re: Mystery LS1
Not sure what you mean by a hoop, and where it is located on the drive shaft, but on my 95 Z I had a Propeller Shaft Slip Yoke, see the Photo. I had it removed, and the drive shaft rebalanced along with new U Joints when I replaced the Transmission Ouput Seal and the Rear End Pinion Seal.

Re: Mystery LS1
I think he means driveshaft safety "loop"......

Never installed at the factory. There is just a sheet metal brace across the bottom of the driveshaft tunnel, where the red cross-support is in the photo below.

Re: Mystery LS1
I have yet dynoed the car [ plans for future ]. I have determine the harmonic balancer is aluminum. the# at the back of the block on driver side is 1305MK579365.
those last 6# have no common relation to the last # on the vin, and any thing else is subjective, yes I had a try at 0-30 but was tire limited.
is it really true hood , tailgate,doors , roll bar and front fenders, are made of aluminum or fiberglass.
thanks

Re: Mystery LS1
GM parts houses show that as a power steering mounting bracket, not a head.
