Can someone tell me the difference between a Camaro LS1 and a vette? I searched the topic but didn't find anything so sorry if this is a drawn out question.

Cam specs, different oil pans and Vette LS1/6 not having an EGR system are maybe a couple that come to mind. Of course there's also the fact that Vettes have a true dual exhaust vs the F bodies Y-pipe, but that has nothing to do with the actual engines per se. By and large there are far more similarities than differences. HTH

Corvette fly-by-wire throttle, Camaro NOT!

What about internals? Crank, rods, pistons, heads, oil pump, etc.

F-Body engine parts are about 10 timess LESS than Vette parts.

Will internals work?

Guts are the same! Exhaust manifolds, oil pan, lack of EGR, and throttle bodies. Thats about it.

Dont know about pre 2001, but for 2001, 2002, the cam is the same part numbr, as is the exhaust manifold. I think that the only major part that is diff. is the oil pan shape. By the way, don't let anyone tell you otherwise, the F body LS1, although rated at 310 HP, pumped out the same 350 HP as the Corvette.

Yes internals will work. An ls1 is an ls1 no matter what it is in. 80% if the fbody stuff is the same under the hood of a vette, and most of the parts are the same infact. The ones that arnt are just cast differently.

As far as internals everything is the same. (TB and manifold arent)

WHY are the F-body cars then not rated at 345/350 HP ?? Is it because GM wanted to keep the numbers "looking high" for the Vette, to justify its price?

Infact, I think if GM HAD advertised F-body at 345 HP, they might still be in business. And those numbers would look better on the charts and for advertising for the F-body, when compared against the Mustangs, which are still very much in business (unlike F-bodies).

Its confusing for me, why LS1 in Vette and F-body are not rated the same. I understand the weight difference in cars and design, etc. But the engine ratings should've been the same.

WooHoo - off to look at the F-body engine sites!!!!

Corvette Tax can kiss my a$$

Hey EG,
Looking at the F-body sites is a great idea. I checked out a few things last week and was shocked at the obvious Vette tax for LS1 upgrades we pay.

EG, please let us know if you find any hidden treasures! I'll do the same.

I had a 1998 Z28, then a 2000 SS Vert, now a 2002 Vette Vert. The 1998 LS1 had a different cam than the Vette's LS1, the 2000 was exactly the same LS1. If you ordered (from the factory) the SLP package (which I had) which included different wheels and exhaust, the HP was near the Vette's HP. In (I think) 2001, the SLP package also include a low restriction airbox and the advertised HP was 345. My SS was a great car. The top was hydrolic which I really miss in my current Vette. Here's my 2000 SS Vert:



You can tell if Camaro's had the SLP option by the exhaust: Regular exhaust had one pipe on each side, SLP had two pipes on each side.

GM plays those games all the time. The L19 454 I bought out of a 99 suburban was rated at 295HP. If you look at the rated torque number at the peak HP and work the math, its really 305HP. But when the engine was released in 96, the Corvette had a 300HP engine, and you can't be having a truck with more HP than the 'vette right?

Excuse my ignorance about f-bodies and lack of direct corvette related talk, but what seperated the z28 from the SS? Different cam? manifolds? I always thought the SS had the "corvette engine" and the z28 had something different...

screw991le

The Engine is the same, the internals are the same, the cam is the same, the tune is the same etc etc.

Why do you think Z28s and such have the same dyno #s.

I have owned plenty of Camaros and they were well under rated.

The engine comes from the same factory. Just a few outer parts are different.

Look up the part #s if you think they are the same.

The Cams and rods and pistons are all the same part #s.

I used to love while at the track the Z28 would click off 13.4 quarters and the Vette owners would say "oh got some mods?"

I love my vette, but I paid 19k for my 99' Z28 1LE brand spanking new and 7 miles on her.

But a Vette is a Vette and a Camaro is a Camaro

0EG@EnglandGreen

I'm not interested in stock Camaro intake/exhaust/TB or cam - or stock anything actually. It's the aftermarket internals like Jesel rockers, chromemoly pushrods, valves, Crane valve springs, Rhodes lifters, Manley oil pump, timing chain etc. etc. etc. that has that stupid Corvette tax added.

Why would I pay as much as 5-10 times as much for something I can buy from Summit Racing at a tithe of the cost???

I'm off to Jegs and Summit Racing. I'll keep you folks updated on what works in my 01 Coupe!

Flywheel maybe, but that single exhaust doesn't help a whole lot. I used to have an F-Body. Pontiac Firebird Formula 6spd. It used to surprise some of the T/A guys occasionally.

Back in the early 90's, GM entered into an agreement with SLP (Street Legal Performance) to offer performance enhancement upgrades to the Pontiac Firebirds and still have a factory warranty. There were a variety of things that could be ordered, and the package included SLP putting the "FireHawk" logo on these cars too. Most of the conversion work involved better exhaust, Air intake (with new hoods),Auburn rear-ends, specific wheels, etc. To my knowledge, none of the engines themselves were modified. The "Firehawk" designated cars were shipped directly from the St. Therese assembly plant in Canada to SLP's Canadian facility (about 20 minutes by truck), where the conversion, depending on what was ordered, was done. The vehicles were then sent straight back to the GM plant for shipping by rail to the U.S.. Sometime, at a later date, GM wanted to revive the "SS"
name for the Camaro buyers and SLP started doing the conversion work for them too. I've kind of lost track of what ever became of that arraingment over the last few years of the F-Bodys' life, but it seems as if GM did the same thing to SLP that Ford did to Carroll Shelby and that was to bring everything back "in house" so-to-speak and tell Carroll "buh-bye"
BTW, this was the main reason that SLP was offering many of the wheels, tires, etc for sale to the public through their own company. These were all brand new "take-off" parts that they would wind up with after the conversions. HTH

2003 F-Bodies did NOT pass federal crash standards. Another reason why they were killed.

With 4,000 miles on the clock and a borla catback and cold air lid, my 2001 6 speed Z28 put out 318 SAE corrected rear wheel horse power (340 tq.). My friends 2000 Vette pumped out 299 HP (305 tq) on the same dyno, the same day. He was pissed. That is why, I think the camaro was underrated. I know the Vette is a better car, but I have a back seat, which is precious to me! We all make out decisions and compramizes in life, right. Tough choice, (C5 or Z28) huh? Life ain't so bad when you have to chose between those 2 cars!
