Okay, now you are talking about Z06's,,,,thats an entirely different animal all together. This thread started out comparing apples to apples,,,,a vette to f-body with same engines,,,,where does the Z06 fit into that? Larry.

Grims is correct ..
1997-
100 30th Anniversary Camaro SSs were modified by SLP (Street Legal Performance) and included a 330 hp version of the LT4 engine. While the LT4 made it the fastest Camaro available, it was also by far the most expensive with a price of over US $38,000. The Z28 of this particular year made 285 hp (213 kW) and 325 ft•lbf (440 N•m) of torque with a Corvette derived 5.7 liter (350 CID) Engine.

Not only Camaro but the Firehawk's for 97 also had 330hp LT4's

(FWIW, The LT4 Corvette was 330hp, but has NO SLP parts... it was all genuine GM. If you put SLP parts on an LT4, I would think you''d have more than 330hp.)

An SS SLP is an SS that was sent to SLP to get thier performance package, but had nothing to do with LT4 stuff... they are LT1's...

Firehawks are different all together. Thats a limited edition car.. like a Blackbird.
Those 100 SLP LT4 SS's are very rare... ( Very nice too! )
the other 99.99% of SS SLP's are LT1's.

And the link to the other thread was just to show why the Corvette's technology puts them ahead.

I've heard of people putting LT4 heads on their LT1 F-bodies, how does that work, and is it worth it?

Corvette got ported Exhaust Manifolds and a 3" to 2 1/2" Exhaust with Dual Mufflers.
Corvette PCM gets higher PCM Air/fuel ratio.. which is why usually 91 Octane is required.
Corvette gets newer parts by atleast one year. If the Camaro has an LS1 intake, the Vette's gets an LS6.
Corvette has bigger fuel injectors, or they spray more.
plus a shitload of little internal and external differences that make it put out more power.
Every year, even though the differences might be change depending on year, the Corvette will be 3 steps ahead.


It will always have the better tech and more flow... even though the core of the motor is the same... simple as that.
And even on a 1/4, its going to take alot more work to get an Fbody, even with the same motor, to run similar times.

Still dont get it? i give up:notworthy
He asked about more power.
Well, Like I have already stated, even IF they had the same power output, the Vette would win.
Yes the Vette might have 20 or 40 more hp, buts its technology and design, tuning, technology, fiberglass body and chassis that make a Vette compete with cars 4 times its price range on all types of tracks and tests.
Ecpecially handling, braking, cornering, acceleration, top speed, power output.... ..cough cough my throat is getting dry, excuse me

Just because you pop your hood and see the same engine doesnt make them similar.
Camaro = $7,000 with 80K
Corvette = $25,000 with 80K... same engine? Wtf?

In the owners manual for my firebird it recommends 92 octane or higher. When I first bought my car, new, I did alot of research on the engine differences. The only difference in the longblocks is the vette has 4 bolt mains. The power difference came from the intake plumbing and exhaust, and of course the tune was slightly different to compensate for this. I believe the cams are the same part number. If anyone wants to continue the argument, I suggest looking up online parts catalogues and comparing part numbers as I did. That was 10 years ago that I did this. What made the f-body such a bang for the buck was the fact that it is more cost effective for GM to make alot of something, because tooling is so expensive. If the Corvette got an engine that shared nothing in common with any other models, It would be priced much higher. Think ZR1. Or C6 Z06, althought that has a much different chassis as well as a bad ass production engine. But look how much the LS7 cost from GMPP versus an LS crate engine

Not to mention we are comparing apples to oranges here fellows .. Very few vettes got the LT4 .. most were LT1's .. the only bad 92-96 vettes that were bad were the LT5 vette's .. problem is the LT5 shares nothing with either the LT1 or LT4's the engine was a LOTUS engine , 4 cam ... need i go on ... Vette's engine doesnt dyno any diffrent than a F-Body .. anyone wanna try this ?? who has a bone stock F-Body and Y body ??

The LT5 was built by Mercury Marine, do they make the Lotus engines?

Corvette has bigger fuel injectors, or they spray more. The LT1 vette does not have bigger fuel injectors...and if it did it wouldn't make anymore power because stock ones are more than enough.

It still sounds like you are trying to convince us on how great a vette is...we already know, but that's not the point. The original poster did not ask why the vette was faster, he wanted to know why it made more power, and so far you have gone all over vette generations comparing even new Z06s with a discontinued fbody. It was a simple question, why does the LT1 (note LT1, not LT4, LT5, LS1, LS6, LS7, LS98, ect) vette make more power. Not, why is it faster, or how awesome it is, or neato electronics it gets.

Some LT5 History... Engine design was a cooperation between General Motors and Lotus. And, because of the small volume of LT5 engines, GM went outside their own production facilities, to find someone to build the LT5. Ultimately, Mercury Marine was chosen, because of their reputation in building aluminum engines.

God forbid we don't talk about the exact detail the reason the thread started.
And yes, Ive have gone over generations because over generations the Vette has made more power 90% of the time, even with the same motor.
That proves it...

My statements where based on the cars I have seen and rode in.
Want to know all the nitty gritty differences? Do some work and look it up. The exhaust was true, and the fuel injectors are turned up to match the more input from the high performance tune... even if they are the same injector...
And no I don't favor vette's, but I have respect for a better made car.
And don't quote me out of context... its obvious you have something against Corvette's...they seem to touch a nerve with you.

I don't know all the facts and i never said i did, but what I did state was true and that can be backed up by over 100 people in a thread that went over 20 pages about 2 months ago...
Don't believe me, why don't you go to LS1tech and ask.

I understand what you are saying Grims, I am on the same page. I don't have anything against vettes either,,,hell,,,,I own one. But we need to compare apples to apples,,,LT1 vette motor compared to LT1 F body motor,,,,why the HP difference? It had nothing to do with suspension, tires, fiberglass body, etc.... That would relate more to the handling characteristics of a car, not how much HP the engine makes.

When you buy a vette, your not buying it for the extra 15 HP, (again this is LT1 verses LT1),,,,,you are buying ,,,,,,the name,,,,a 2 seater sports car that handles well with a well designed suspension and many other things associated with corvette.

I personally like both vettes and F-bodies, nothing against either, they both have their place and a certain purpose. Larry.

Anyone want to mention drive train loss. Add that to the can of worms. Have a look atthe differences. Hell just look at M6 vs. A4 F-bods. M6 will dyno higher than an A4. Just thought I would throw that little info into the pot.....lol
