Close to stock LT1 dyno
[QUOTE=Counted Out;10475416
And his LT1 (motor) is VERY close to stock.
Nice numbers by the way.[/QUOTE]
Exactly!! Why would you guys even thing full bolt-ons are anything spectacular, i don't consider exhaust & CAI anything outragious by any means, hell the main big gains are in the heads/cam, all we really have that would be considered the biggest gain would be the headers & free'r flowing exhaust, i've got full bolt-ons, sure it runs better, but not near as good if it had a good set of heads/cam, that alone could yeild close to 100 HP is matched right, just my 2 cents.

I didn't realize this tread was a poll...well the little graph thingy didn't come up on my computer, so just put me down for "close to stock".
But more seriously those are great numbers!

ok if you want to get technical if the heads and cam are the biggest part why dont you go ahead and do a head and cam package on a car without long tubes or even a cat back for that matter.
that will be like trying to blow a jet engine thru a 1-1/2" water line good luck.
but either way stock is how the car came from the factory, if you have done anything else yourself, especially rebuilt the motor, i wouldnt consider that stock. especially with full exhaust and intake. getting a H/C package would just be one step further into the process.
but regaurdless they are good numbers and the op already agree'd.
this biatch.

Had I not figured out my motor was redone, I'd dispute that haha. I'm not 100% that I have cat-back, but when I got my car it only had the exhaust and CAI. I did the injectors shortly after, then tune and the rest in my sig. TB isn't installed. I would consider mine closer to stock than the OPs.
only FULL exhaust is the key point. EWP is still good for 5-10hp since ours are cam driven 
So thats 255~hp stock + 25-30hp for the full exhaust and 5-10hp for the EWP and 8-10hp for CAI. Take the lowest numbers and that oddly enough is 293. Take the highest and it's 305, which is 5 less than the other guy who said his buddy's car with the same mods made.

Thanks for the Complement on the Stang. Here is a little vid of it in action:
96 Cobra at DH6 and DH7
What do we know
It really does not matter. To appease the masses, I will no longer call it close to stock on here.
Subject IS over, but there is no reason to lock it. I posted a dyno run with mods. Is good for people to voice thier oppinion as long as it does not get out of hand.
I am by no means an expert on the LT1, but I am pretty sure that GM under rated them a little. So with a few minor mods, they can put more than thier advertised crank HP to the tires.

Actually a 285HP stock lt1, lol. The factory rating does not matter once som one does full exhaust. The only power producing differences between the 275 and 285 cars is the dual cat exhaust.

I've heard many times ours were under rated, but more and more and more of seeing what people make with a stock car (quite literally stock in this meaning), I'm will to say the Corvette was OVER rated. Then again their exhaust is much better than ours, and could easily have a more aggressive tune than the F-Body did. Their cams were a bit better as well, but the differences between F and Y's cams weren't much.

Hmm, you know I've actually heard this before - that the LT1 was underrated from the factory. Espeically the 275HP one. What does the board say?

Wow, what a bunch of crying over nothing.
With headers a CAI and a pump and you're acting like it's now a Top Fuel car.
The car is "close to stock" in my book, but I'm a racer not a show-car waxer...

well the way i see it is the motor has not been modified!
headers only free-up HP
elec. wp frees up hp
cai allows the engine to breathe freeing up hp
i will also go on a limb and say ALL f and y body Lt1s are actually 300+ at the flywheel.....
great job especially w/o a tune!

Good numbers!
All of my LT1's haven't seemed under rated putting out 230 for my current 1994 (275 rated) and 233 for my 1996 (285 rated). Both cars were autos, so I lost around 17% drivetrain loss which seems about right. There have been alot of 6 speed's that put down alot more (250+) though, which means they would have to have been under rated from the factory. Either way, it is what it is.

how is it possible that the OP can have over 290whp with just exhaust.. and you have 230???
something doesn't add up.
