i thought it was a L98 car...

 

i know that L98 means you have a 350 motor, i even checked in my gm shop manual, but this page shows differently.
http://www.chevy-camaro.com/chevy-ca...-third-gen.asp

 

B2L RPO means additional options are requires for the 350 engine.

 

The B2L RPO was a group RPO for all options required when ordering the L98. In the case of 1987, ordering the L98 required you to get J65, K34 and a few others. L98 was the engine option. Most books, even the white book refer to the 350 incorrectly as B2L. GM uses L codes for their engines.

 

My gosh, doesnt anyone search anymore? This question gets asked at least once a week.

L98 means 350 TPI engine with aluminum heads in a Corvette. B2L means delete the aluminum heads and put in iron heads for an F-body.

 

Wrong, very incorrect information. You should do your reseach before posting.

 

I agree. L98 on an Fbody means 1987-1992 350-TPI. On a Corvette, they did use aluminum heads versus the steel that the fbody received, but B2L has nothing to do with the heads. Please be sure you have facts correct before posting info to new users.

 

You guys need to look again. While I didnt give all the options B2L made up, I got at least one of them.

https://www.thirdgen.org/forums/hist...ifference.html

To further prove my point, the G92 package is the one that triggers the 4-wheels disc brakes (J65) and the engine oil cooler (K34). These things can also be on a 305 5-speed TPI but those dont have the B2L rpo.

 

G92 requirements varied over the years from just a performace ratio to a package of options.
So don't state G92 consists of this option and that option. It did not.

 

Kevin, what website is giving you this much misinformation? I know it's not coming from TGO. As was stated, G92 is a performance axle and in some years had different requirements. In 1987, the 350 cars came standard with G92, but in 1988, G92 was an option on the 350 cars. B2L is a code for mandatory options required for the 350, including oil cooler and 4 wheel disc. I do see that I made a mistake above. RPO K34 is cruise control. RPO KC4 is oil cooler.

 

Yes, its coming from here. I've been here since the end of 1998, and what I've posted is what's always been posted when someone asks. Where are you getting your info?
Both of you guys say that B2L means "additional options for the L98 engine." Well, you think maybe one of those required options is the iron heads instead of the aluminum heads? I mean, something had to trigger the change in heads, and it could be that code or any other RPO code on the car, right? The L98 in the Corvette and the L98 in the Camaro were different engines because of the heads and the way the EGR passage was routed. However, the LT1 and LS1 in the 4th gen F-body and the C4 and C5 Corvette were the same engine, hence no different code in the 4th gen f-body to distinguish the two.

 

Wouldn't it make more sense for the corvette to have a RPO code that added the aluminum heads rather then having it deleted with B2L? I would have assumed that the "standard" L98 would be the iron head version and that the corvette would have had an additional code to upgrade it to vette specs. I still think that B2L was as Scott describes it, the manditory upgrades that come along with the L98 instead of the iron head L98 being manditory for B2L.

 

Look at it from GM's point of view. The Corvette and its engine are the flagship, so the Corvette L98 is the standard, not the f-body L98.

 

yeah i think i would have to agree there since the vette got the L98's first i doubt they would make an extra code to identify it from the camaro engines

 

If the logic behind B2L means pulling aluminum heads and substituting cast iron, then where's the code indicating the same on 94-96 B-body LT1's?

It's something of a retarded argument anyway, since the Corvette L98 was originally an iron head motor. If they had to change the RPO to change the equipment, then wouldn't the 85-86 L98's have a different RPO then the 87-up?

Whether B2L was to signify changes in the engine itself, or the standard equipment attached to it, is really a moot point. There are plenty of RPO codes that could be debated. GM defines L98 as Engine 5.7L V8, and B2L as Engine Package, 5.7L V8. Sure seems like L98 is the engine code, and B2L has to do with the subsequent components.

 

I agree, the BL2 Rpo was just a add on for required optional equipment. Previous Posts are just a CYA type about the different heads on the L98.

 

"However, the LT1 and LS1 in the 4th gen F-body and the C4 and C5 Corvette were the same engine, hence no different code in the 4th gen f-body to distinguish the two."


Kevin I think you are wrong about this same engine deal at least for the 4th gens.


There are some differences between LT1's. The Corvette got 4 bolt mains and Aluminum heads. The F-body cars got 2 bolt mains and aluminum heads. The '94 - '96 Buick Roadmaster, Cadillac Fleetwood, Chevrolet Caprice, police cars and the Impala SS got the 5.7L with 2 bolt mains and cast iron heads and was rated at 265hp. There was also a 4.3L LT1 available in the big cars which is indistinguishable from the 5.7L, except for the different casting number and 4.3 cast into the top of the block just ahead of the bellhousing flange.

'96 The LT1 picked up 10 extra HP in the F-body cars with the addition of a second catalytic converter. The LT4 is introduced as an option in the Corvette only and was rated at 330hp. A few of the supertuners offered special editions of the F-body cars with LT4's in them apart from the factory.

LT1 Horsepower Torque

F-body 93 – 95 275 325

96 – 97 285 325

Caprice 94 – 96 260 330

Corvette 92 – 96 300 340

LT4 96 345


LS1 is introduced in the redesigned 4th gen F-body and is rated at 305hp. The LS1 engines used in the Corvette and the F-body are essentially the same with only minor differences. The Corvette has coil covers, different exhaust manifolds and the alternator mounted high on the left side requiring a remote power steering reservoir. The Corvette LS1 has a slightly different camshaft profile which allows the engine to meet emissions requirements without using an EGR valve. The F-body has exposed coils and the alternator mounted on the left side below the power steering pump with integral reservoir.


'01 F-bodies received a new cam profile which allowed removal of the EGR valve.
2001 and 2002 F-body receive the ZO6 intake manifold.
LS6 version of the LS1 available in the Z06 Corvette 385hp.
Corvette LS1 rated at 345 hp


'02 Corvette LS6 receives 405hp
Last year for the F-bodies.


LS1 Horsepower Torque

F-body 98 – 99 305 335

00 320 345

01 – 02 325 350

Corvette 97 – 00 345 350

01 – 04 350 375

LS6 01 385 385

02 405 400



I hope this clears the air that these engines may operate the same, look the same, blah blah blah but they are far from the same. Not being a ******** just wanted to clear the air at least on this issue.



http://www.grandsportregistry.com/lt1vslt4.htm here would be the source. Happy reading

 

While I don't agree with everything I just read, I do agree that the engines are different between the Vette and the Fbodies. The engine designator of L98, LT1, LT4 and LS1 designate the base engine block. Again, the engine will be built differently for the different models it would go int. The block is the key.

What I disagree on is the 97 SS LT4 was not built by tuner companies. There were 100 made by SLP. The same company authorized to create the SS to begin with. The 100 LT4 SSs were GM authorized equally as the regular SS. It wasn't until 98 that the window sticker actually showed the SS option, so all 96 and 97 SSs built by SLP are factory authorized cars.

 

I agree with SLP no being a tuner company same as ws6.

At least this aspect was settled.

U guys are aware that the L98 is available in australia based impala I think, although it isn't the tuned port version.


Off topic a bit but what about the ZR1, it was a lotus engine i think but dohc , wasn't it the foundation for the lti, lti foundation for ls1, ls6, ls2 etc. Anyone ever heard of the zr1 transplant into a f body and if not why hasn't anyone attempted it?

 

The 'LT1' based 4.3 is not an LT1, it's an L99.

The ZR1 swap was done in a thirdgen, by GM. It shares virtually nothing with the LT1/4 series, or the LSx series. In fact it's closer to the L98 then the others since it's a TPI engine (in theory). People don't do LT5 swaps into thirdgens, because the cost to benefit ratio is crazy.

 

I have a friend who thinks it's hilarious that GM would put a "Mercury" engine in a Corvette. ZR1 is a Mercury (Ford) engine.

 

I don't think MERCURY MARINE has anything to do with FOMOCO.

jms

 

anybody have any links to the 3rd gen with the zr1 transplant. I've searched the web and came up with nada. Would just like to see this.

 

Those engines were produced in such small numbers that each one is accounted for. ZR1 owners know the location of everyone of those cars & engines. Dumb question about that kind of swap.

 

There's at least a snapshot of a LT5 sitting in a thirdgen engine bay in one of these two books... I'd doublecheck and scan it in, except my books are all in storage. If I remember correctly it was a GM project. Never a production deal, or a kit offered or anything like that... They did a lot of stuff like that, BBC's, LT1's, the LT5, etc. The second one I linked is a better book, and the more likely of the two to be the one I'm thinking of.

http://www.amazon.com/Performance-Ha...7868734&sr=1-1

http://www.amazon.com/Modify-Camaro-...7868904&sr=1-1

You probably won't find anything about it online, because it pre-dates the internet by a few years.

 

That's one of those dream projects. May not be the fastest, may not be the wildest, but it just seems at home in there. Uhhhhhh if only I'd not lost that damn lotto ticket. LMAO

NOw that we have gotten WAY off topic arguing about crap that has nothing to do with 3rd gens...

To answer the question:
B2L - PERFORMANCE PACKAGE & ENGINE PACKAGE V8 5.7L TPI
L98 - 5.7L TPI engine

The fact that both the Corvette & the F-body both used the L98 is moot, they are similar but as discussed the vette used the aluminum heads. Same thing as mentioned before for the LT1 and the Large cars vs the Vette/F-body from 94-96. But those cars are not third gen. THe point is that they used the same engine designation, but slightly different varients of the engine.

The question I assume by the TITLE OF THE THREAD was B2L RPO?
THIS IS A PACKAGE RPO, it has nothing to do with the engine other than the engine was included IN the package. Much like the 1LE (88+), WS6 (86+), W66, W61, W6, Y84 were ALL packages, Although they determine either a trim option or a performance option, they do not distinguish ONE single item but many items.

THe case in point, 2BL was the following (from Pontiac)
From 1987 thru 1990 the 2BL package remained the same:
MXO - Automatic Trans
G80 - Ltd slip axle
KC4 - Engine oil cooler
J65 - 4 wheel disc brakes
WS6/FE2 - Performance suspension

In 1991 the 2BL package was
MXO - Automatic Trans
G80 - Ltd slip axle
QLC - P245/50ZR16 BSW tires
RP6 Performance enhancement group
N10 - Dual convertor exhaust
FRONT DISC - REAR DRUM & 3.23 rear axle
WS6/FE2 - Performance suspension
NA w/CC1 Hatch roof

In 1992:
MXO - Automatic Trans
G80 - Ltd slip axle
QLC - P245/50ZR16 BSW tires
RP6 Performance enhancement group
N10 - Dual convertor exhaust
J65 - 4 wheel disc brakes
WS6/FE2 - Performance suspension
NA w/CC1 Hatch roof Exc on FOrmula w/PW7 Wheels

the L98 is the ENGINE, B2L is the PACKAGE as listed above. Heck some of you should really do your reasearch... The B2L does not directly designate the IRON heads anywhere in official literature, however this is how they all came in the F-body, SO it would be easy to ***-U-ME that it was part of the package, but it is probably not the case.

with that said I will leave you to your pointless argument...

Scott got it right in post 4, it should have ended there...

John

 

91zMAN thanx. Now doesn't that looke at home, cept the vette script.


John you seem a little upset and uptight. Not getting any at home?

 

John's right. The subject is about B2L, not LT1 or LT5. Please keep it on subject.

 

I know this is an old post but for people looking these things up today, L98 means 350 motor regardless of what car (corvette, trans am or camaro). I have a 91 Z28 and my RPO clearly stats “L98”

 

And you have B2L... B2L was the package, L98 was the engine, in that package. Read post 28

 

You have an L98 RPO Engine, with the B2L RPO for Cast-Iron Cylinder-Heads, instead of Cast-Aluminum Cylinder-Heads.

At that time; the Corvette Sub-Division of the Chevrolet Division...
Did not want any other Vehicle to have the L98 Engine with Cast-Aluminum Cylinder-Heads.

The Corvette Sub-Division had a massive say in how decisions were made at GM.
