I was just reading on another website how if you have an LS1 camaro and you change just the cam and that's it, you drop from what, low 13's to 10.21. Yea right. If that is all you have to do we would all be running 9's or 8's. Just thought I would post and get your input....

Post the link to that website. I'd like to know what magic stick knocks 2 seconds off of the ET.

It more than likely came off of ls1tech.com

Sometimes those f body guys are just as arrogant as the fox body mustang guys. :(

My car used to run 9.70's @ 145 with a stock station wagon motor....

you could be solid in the nines if you got some of those trick turbine fans to put in front of the throttle body.

Aren't you glad you joined Chevelles.com? Don't you wish everbody would? Not. Leave those guys over there.

Maybe with a 300 shot and a good tune, stall and gears. I will say LS1s are like race-prepped blocks from the factory. Sometimes those LS1 guys think their motors were touched by God.http://i5.photobucket.com/albums/y178/FunkyuNova66/smileys/rolleyes2.gif But I highly doubt a cam alone would get you anywhere near 10.21s. I have a friend with a 99 SS Camaro, big cam, good tune, 3500 stall converter , 4.10 gear and a 175 shot and it runs 10.80s spraying the entire 1/4. So no...someone is smoking crack over there at LS1tech.

Not knocking the motor just the claim.

You too? Dang!

Hey, post the link up , lets invade! :hurray:

Let's not and say we did. Those deals always cause major headaches for mods and admins on both sides.

I agree. I just wanted to know how a cam change dropped ET by 3 seconds. LOL I think we would all stand in line for that cam!

Stock eliminator guys are running 10's with only a cam change, new computer and blueprinted LS1. These are pure race cars with all the bells and whistles, but the engines are all stock except for the cam. I bracket race against them all the time.

Is that like the guy who put dual exhaust on his '68 Mustang and got 600 HP? He thought he could beat my 375 HP '69 Camaro!

The LS1 is an outstanding motor and guys have went 10.30's cam only, but with supporting mods like valvesprings, gears, electric waterpump, so on and so forth also not to mention the car is completley gutted and has a raceweight of 2800 2900lbs. It is a very potent motor it comes with cathedral intake ports and a 15 degree valve angle stock, as well as 6 bolt mains, and a crank w/ chamfered journals. The heads and cam package I run now on my stock shortblock has run 10.51 @ 134MPH, but that is small beans to the F2 procharged big block I want to put in my 72 Malibu, nothing beats some raw chevy bigblock power.

I was just messin....Im too lazy to sign in. :beers:

So let's see, you take a holesaw to the car and remove 1000 lbs of weight. Strip out everything that was not welded down. Fiberglassed everything else. Race prepped the tranny and convertor. Put in a Race prepped rear end and suspension components. But the only thing mentioned is I changed the cam and now go 10.20's all day long. Oh, and this is my daily driver. Sweeeeeet....

So I swapped out my rear tires only and now I run 9's. Awesome, I see how it works.

Yeah i added an air filter on mine and it runs 7's now....................hahaaha

These are pure race cars with all the bells and whistles, but the engines are all stock except for the cam. I bracket race against them all the time. That and about $4000 of undetectable head work and special transmission gears and so much other B.S. it would take a week to post it if you could find it all out in the first place. One top dog LS-1 racer is using a C5R race block. That only sets you back six thousand and change not to mention machine work. I'd bet they have some computer changes too along with the equipment to eliminate the factory rev limiter. One of our local racers with a bracket race 383" LT-1 recently put in a FAST controller and picked up 2.5 tenths and 4 MPH with that change alone.

The first time slip was 1/4 mile and the second was 1/8th :D

sorry buddy u r talkin crap

sorry buddy u r talkin crap He was just relaying something he read somewhere else, not making it up.

LS1's are awesome engines. I've tuned some stock eliminator LS1's and they certainly make power unlike a std. SBC. I know they do some fudging of the rules, but you don't need to do much to those heads anyhow.

From what I have seen most stockers overcam them as they don't need much cam to go 7500 making power because the cams are so good.

All the stockers that I know of run aftermarket tunable EFI which is legal. With those square lobe sticks you couldn't hardly tune a stock ECU.

I'm with you Harold, no one is going 10's on bone stock ls1 heads, not even the ls6 heads flow that good stock. I'm a member of ls1tech and there are some real wack jobs over there but on the other hand there are guys who know a ton and share it with others in a respectable way. Keep in mind their membership seems to be guys in the age bracket of 16 to 25 so you'll get inexperienced comments from time to time, so don't a couple of bad apples spoil the bunch :) .

I hear you redneck, the guy here that just went to the F.A.S.T. - ECU went from average of 10.40 flat and a best of 10.20 with his factory ECU to a 9.95 with the FAST unit. This is a 383" LT-1 with heavily ported heads and 16.4 compression. He said the motor was stuck with the factory rev limiter coming in at about 7200 RPM, now it will go 9000 and has no trouble running all the way through without having to use the overdrive which he has broken at least once. Most flow improvements in high flowing heads are within 1/4" of the valves anyhow.

A LS1 (Al Corda) with a Holley ECU was the first stocker in the 9's, they easily go 10's.

You can say that they are illegal and all that, but they are teched. For a car that is NHRA stock legal to go 9's, that is something, no matter what "gets buy tech".

Al Corda's Firebird is the one with the C5R race block because it kept breaking stock ones. P.S.... These cars are VERY light too, somewhere just over 2900 lbs. Thats about the same as a '66 Nova 2 dr. H.T.

sorry buddy u r talkin crap

Context, victtor, context.

You guys are going over board here, you cannot deny that a quick cam and chip change can take an LS1 into new territory. The 10.2 claim might be a stretch, but small changes are big here.

If I had stupid $$$, I would defintely build me a nitrous/turbo daily LS1 powered vehicle. You say I can't go tens???? Certainly would have the hp to do it.

first off, the guys at ls1.com are honest most of the time. post the link because i dont think you read it right. the ls1 cars respond very well to mods. hell even the 5.3 truck heads are 192cc 15 degree heads! i dont believe 10.0s from a cam change. but solid mid 11sec with cam only and suspension i have seen.

I believe tens from a cam change. He doesnt tell you that he has lots of suspension work in there. Also lightening the vehicle and tons of dyno time to tune. Trans tuning and rear gear swaps to optimize the combination. Still, its happening without stroking and poking the motor. Or, if you choose not to optimize what you have you can stroke and poke, slap on some good heads and go tens. I think it is pretty impressive what they are getting these engines to run in purpose built vehicles. Now, i dont believe that you could buy a used F or Y body vehicle, change the cam and poof your in the tens. Not gonna happen. Theres far more to it than a cam swap obviously.

Am familiar with that car... He owns the local track.. More than a cam change going on there :D

I have a buddy with a 2000 Vette with a stock-displacement LS1 who runs 11.90s @ 126mph all day on street tires. Should be solid 10s if he could get traction in the first half of the track. It "only" took heads, exhaust, intake, tune, 3100#(?), 4:10 rear and oh yeah, that magic cam to get there. Gets awesome gas mileage with the 6-speed. Makes me sick... The LSx series are impressive engines, can't wait to get mine done.

FYI, Blue printing a motor does NOT leave it stock! :clonk:

"Blueprinting" an engine is when you change the tolerances to the best they can be within the known specs. I guess as soon as you change your spark plugs, your engine is not stock anymore.:clonk:

No FYI needed here.
