Your chances are extremely good, I expect the chevelle to post something in the 15s

Damn that slow figured it would be better haveing 450hp

He is... Depending on how you optioned the 454 chevelle you could get the ls5 454 which was 360hp or the ls6 454 which was rated at 450. If his dads is the ls6 version then the car is capable of low 13's to high 12's stock. In 1970 I believe motor trend drove one to a 12.8 at 109 and with a set of slicks it would ip into the 12's better. However his ss should be BOTTOM 12's if not 11's with a good driver

70 chevelle ss 454 ls6 engine completely stock factory rated at 450hp.

Ohh didn't know it has the ls6, didn't most come with a 360hp 454? Either way I have never seen on run with the ls6 that I can think of but I have also never seen a stock "muscle" car run faster than 15's either

Edit: now that I Look, it appears im talking out of my *** and magazines have said they run low 14's and even into the high 13's, but that should still be no match for a cammed ls1 car.

If the Chevelle doesn't have any decent tires on it ,,,,you will spank him hard.

You'll outrun him even if he has a ls6 454 on slicks. With that kind of power you should run 11's @ 120ish.

Is the Chevelle an auto or a 4 speed? A well tuned LS6 4 speed car with drag radials and a very good experienced driver will post a 12.6 at about 110. You should have him covered even if he has all that going for him if it is truly bone stock.

Actually more chevelles came optioned with the ls6 option than the 360hp ls5 because it wasnt that much more money over the standard 454. Go on youtube and watch nhra stock, there are plenty of stock muscle cars running 13's theey even have stock yenkos or zl1's running into the 11's on slicks.
This^^ 12.6 on tires was not unheard of for that car however with the stock polyglass tires it wouldnt do much except blow the off halfway down the track lol

My money on the camaro. The Chevelle is giving up a lot of weight to you.

FST SS

camaro all the way

your camaro should take him, those 454s put out A LOT of torque and without a good tire they are very tricky to drive. Even if you do get them to hook, they are heavy. My friend has 70 SS, LS6, 4:10s, TH400- the best it has been was high 12s ~113.

450 GROSS sae hp. its more like 370 by todays SAE net. they make 280-300rwhp SAE net.

you murder it badly.

ive raced most of the muscle cars at a track of that era and its never been close when they are stockish.

zz4camaro1980

Not saying its not true, but I find it very hard to believe. My friends car is a beast, it will bake off second gear at 1/3 throttle. We have never had it to the track though. It was his dad that had it at the track many years ago, I think they have a dyno sheet though- ill see if I can find it.

Put a pair of Mickey Thompsons and a 1" rear sway bar on it and you will find out if it is a beast. An A Body will spin the tread off of a tire with a 350 2 barrel unless you put a tire and a sway bar on the back.

I know doing a burnout doesnt prove much, but there is no way an LS6 454 only put down 319 ft-lbs. My friends will barely run on 93 octane (we have to run race gas or else it pings like crazy- gas was a little better back in '70), im betting they knocked the timing way back to run 93. And like I said, the car has been in the 12s, it takes more power than they show in superchevy to get a car that big down the track that fast.

Sticks n Stones

No matter what you are going to pull him, even if he is on slicks. But as to how they do? well, if the engine rebuilding did a special blueprint build on the motor, with a cheater cam and other engine guru mods that engine could be making 550 crank horsepower SAE and be called "stock". I've seen it every which way, and you never know unless you were there for the build.

If it's truly stock, and on decent street tires, he will probably run mid 13's after he gets the launch halfway decent. those cars shine in the 30-90mph range where there huge torque curve can assist them. For the record, I had a good friend of mine who owned a engine shop that had a so-called stock LS6 in his '69 camaro that ran high 10's on slicks 3200 stall and 4.10 gears, 12's on street tires/ 3.73 gears. Even with the iron 454, heavy turbo 400, and 12 bolt rear his car weighed 3100 pounds. We weighed it on the same scale, same time that I weighed my stripped '78 Z28 which weighed 3420lbs and my brothers IROC that weighed 36xx lbs.

even the mighty ZL1 only makes 375 crank hp SAE net. its been put on a dyno in totally stock trim. it takes race gas because the chamber suck so bad.


the l88 square port heads only flow 310cfm. they make great power with the rest of the combo dialed in. EDIT: very similar to LS3 heads.

the torque you are feeling is low end pull. my 454 in the motorhome pulls like hell off idle. still only makes 410 lb-ft though.


a straight six pulls like a big block to 1800rpms.
