What year of Camaro did the LT1 cam came from. I'm asking for the cam that would be a good upgrade for a 305 lo3 (the one that everyong is talking about). Are all LT1 V8? are some of them V6? I just whant to get the right cam thanks..

 

They're all 8 cylinder engines in 93-97 f-bodies and vettes and some impalas and caprices from those years too. Look for a 96 or 97 F-body cam those would have the best specs and be your best bet.

 

They came in camaros from '93 till '97 and vettes from '92 till '96. Not sure about caprices but they also cam in all Impala SS's. The 1995 cam had the biggest specs and the 96 and 97 cams were actually the smallest. 1995 is the year to get. That is why I bough my 1995. All of the camaro cams were relatively the same size. Only small differences. I will try to find the link that has all the years and thier respective specs.

 

Really? I had always read on this site that the general consensus was that 96 and 97 were the biggest because they had a little more lift on the exhaust side. Could be wrong though if you say 95 is the biggest; I never really looked into the specs by year.

 

I am still trying to find that spec sheet. I know in 96 and 97 the intake side was smaller and i thing the exhaust stayed the same. I know lift stayed about the same but the duration varied. 96 and 96 models cam with 10 more horse but that was do to the implementation on a dual cat set-up instead of one single cat.

 

Ok I found it and the 94 -95 cam was the biggest.

1993 cam
Intake - .450
Exhaut - .450
LSA - NA

1994 and 1995 cam
Intake - .450
Exhaut - .460
LSA - 116
230 and 238 duration

1996 cam (I think the 1997 cam was identical if my memory serves me right)
Intake - .447
Exhaut - .459
LSA - 117
205 and 207 duration

So you can see the lift figures stayed on par but the duration certainly changed.

 

What year do you guys recommend for 91 camaro TBI that would not need computer burning...

 

230 238 duration! Are you sure that's accurate? That's awfully high for a stock GM production car.

 

LOL......

That's SUPPOSED to be 203/208

That's the cam I just sold on Ebay. Oh well.

 

The Caprices got the LT1 starting in 1993 also.

They also had a paltry 4.3 V8. I don't know what cam those got. Probably LO3 left-overs.

An Impala ain't nothing but a pretty Caprice. Don't let anyone tell you otherwise.

AAMOF, if you got a Caprice with the towing package, you got a 3.42 rear end compared to the Impala's 3.08. Quicker acceleration.

 

It is supposed to be 230 and 208. Typo on my part. Just click on that link and check it out.

 

i am sure it doesn't have 230* at .050, it might have a 230* advertised <shrugs>

 

The Caprice did NOT have the LT1. Repeat did NOT! It had a 265ci motor. With the same fuel injection intake manifold as the LT1's. This Would be like calling a 305 LB9 a 350 L98. It also had iron vortec heads. Not sure of the hp, but I think it was 240hp. And it was only avilable with a 4L60 auto trans. The Impalia SS did have a LT1, but it also had the iron vortec heads. You could get a 6 speed or the 4L60E auto trans in it though. Its hp was still under the true LT1's found in '92-'96 Vettes and '93-'97 Z's, TA's and Formula's.

 

the only caprices to get the lt1 cam were the police packages, unfortunately ive had the opportunity to speak at length with police officers about them. and not all the police cars have them either. most likely to find them in 94-95 models. look at their quarter windows, the ones youre looking for should be notched at the bottom right side as opposed to just triangled shape. its amazing how many people think caprices had lt1s. very common misconception.

 

Yea I think you are right. That seems a bit high. I think they fudged up the duration specs. I didn't really pay attention when I posted the spes but I have gone back and checked they out. Soemthing is goofy with the duration for that year.

 

I used to sell them BRAND NEW!!! I think I know what I sold

The 4.3L was the standard engine. The LT1 was optional on the LS and standard on the wagon.

I was mistaken about one thing. It wasn't until 1994 that the LT1 was optional.

AAMOF, you couldn't get the towing package on anything except the LT1.

If you doubt my wisdom, click here.

It was an iron head engine. But regardless, it was still a reverse-flow coolant, Gen II block, LT1, 5.7L, 260 HP, 350 cid Chevy motor.

Please educate yourself before you continue mis-informing others.

 

WHERE did you hear that???

The Impala NEVER came with a 6 spd. NEVER.

Again....

 

LT1 cam = peanut cam

 

Rode in an Impalia with 6speed about 2 years ago. Parked beside it at a groecy store when I came out dude was asking about my car('97 Z28 white with hugger orange herdige stripes 30th Anv. Edition 2000 made in all 100 came with the LT4, 842 SS, 1147 Z28, 13 were promotional never sold). He said he had only got it about a week ago, but it had the 6speed. He said he was 2ed owner. I don't belive it was put in there but all things are posable. Would like to see some GM documention that you could not get the six speed if you can find some. Because I also think I remember something about being able to get one back in '96. And the Caprice was a 265ci, reverse flow cooling iron headed, 2ed gen SBC, Block casting #10168588 It was called a L99 not a LT1. At a glance one could not tell the difference. Not tring to be a dick but just to inform.

 

First of all, that 6 spd must have been put in there because they didnt come factory in those cars. I put a six speed in my 85 T/A, but that doesnt mean that you could get them from the factory that way. Also, caprices could get the LT1. They didnt all get the LT1, but they could. Thats one thing you have to watch if someone tries to sell you one is whether it is the 265 or 350. Not trying to be a dick, but just to inform.

There is something I need to correct that I was mistaken about. PWYP right.

The towing package included the 3.23 rear ratio, not the 3.42.

Sorry. It's been 7 yrs ago that I sold these cars.

Damn GM for giving them up to make MORE TRUCKS!!!

 

Towing package on the Caddy Fleetwood was a 3.42, though. I'm talking 94-96 Fleetwood here (LT1).
Civilian LT1 caprices got a 2.93 or 2.56 rear. I don't know if there was any other. Impala SS was 3.08. 3.23 was used in the L99 (4.3L V8) Caprices. Wagons did come standard with the LT1 in 94-96, but a lot of them had 2.56 gears. The only 94-96 B-Body to NOT get the LT1 was certain Caprice sedans (police package OR civilian). The rest (Impala SS, Roadmaster sedan or wagon, Fleetwood or Caprice wagon) all got LT1s standard. They are "true" LT1s, with iron heads. And these iron heads flowed better than early aluminum heads.

Also, 94 was the first year of the LT1 in the B-Body, no exceptions. And nothing but the 700R4, 2004R, 4L60 or 4L60-E ever came standard in a B-body (if we are talking 4-speeds).

T56 conversion is fairly popular among the LT1 9C1 or SS crowd. I've driven one. Fun.

 

All right I was wrong!! Will ya ever forgive me, or do I have to hang my head down and go to some other lowley F site? Here is a link with a lot of info about the LT1 and L99, good bit of cam info(what this post was about) on it.

I checked out this cam at work.. I work at a GM dealership BTW.

95 LT1 cam specs. Part # 12551 705 GM

Intake .447 duration 201
Exhaust .459 druation 208
LSA 117

 

Thanks for the fix. After further research I too noticed that their advertised durations were off. 230 and 208 are too far apart. Their lift figures seem acurate but not sure about the other durations for other years.

 

Thanks guys...
