Slicks are way too big for that gear.

Low 12's high 11's with about a 26" slick using 3.43's

im plaining on putting a 4:10 gear in. would that be a good idea for a mostly street. those are the only slicks i have. just working with what i got.

jdmille5

with a set of headers and k&n air filter and hypertech programmer you think ill definitely be in the high 11's. is the hypertech worth buying?

I think those slicks will put a lot of strain on the clutch and slow you down.

I'd run the car on a radial, and figure that if you can cut like a 2.0 that you will hit 1.6/1.7's on the right size slick.

I think high 11's with headers, good air induction system, 180 t-stat, and decent AF ratio. HPP3 is really not going to do much for you.

I am going to be putting a LS1 and T56 in a 1st gen camaro this winter, are the first gen camaros with LS1 engines faster than the new camaros

jdmille5

yes, because both cars being exactly equal the first gen. weighs couple hundred pounds less. i was told that for every hundred pounds you take off your car, you become a tenth of a second faster. im not sure how true that is. thats why i have the question posted.

You have to be kidding me??!! Low 12's/High 11's with a stock LS1 and 3.43 gears in a 1968 Camaro??!! Are you sure those numbers aren't a bit exaggerated? I plan to use the same set-up in my 68 Camaro however I have 3.73 gears and have 26 inch tall Nitto 555ZR 275/40/R17's on the rear. What am I going to be looking at?

Hell, if he ran this car in Texas it would be running 10's

Look at it this way, even with a stock motor he should be running a trap speed in the 111-114 MPH range due to less weight, better exhaust system than the factory system (since I am assuming he is going to put a decent true dual exhaust system on the car even with stock manifolds) and a decent air intake system since he most likely won't be using the factory restrictive intake system.

I think that car would do a mid 12 really, first gens do not hook well at all..

Well my 67 with a 470 hp 427 and 3 other similar powered 454's on 10.5 inch slicks with 4.56's gears and lift bars and spools, etc, ran 12.00(never broke 11's) ran a top speed of 115 mph, with best 60 foots of 1.72.

If I could get that stock piece of **** t56 clutch to finish one race, I would bet it would be mid to high 12's. Low 12's and high 11's and trap speeds of 110 usually indicate 400+ hp.

What do you think a stock LS1 with your above mentioned improvements, puts out?

Have you seen the new GTO from Australia coming to the US? It is rated at 360 HP with the LS1. Where is the difference from those 320 HP camaros?

im going to put a mcleod clutch system in my 68 camaro along with pro 5.0 shifter. so my clutch wont be stock. i think i will aslo be able to hook up with 10.5 inch slicks. anyway i have no idea what im going to run. ive heard high 11's to high 12's. i think ill be closer to 12.1-12.2 in the quarter. i have a 427 with about the same specs as you (67ls1CamaroProject) its for sale by the way, it only has 1500 miles on it. anyway i think ill probably run in between 12.0-12.2 in it. the thing is, my engine as a ton of torque but not a lot of top end. dont get me wrong it will put you back in the set but comparably speaking. it will run the 1/8th mile good but it will get run down it the 1/4 mile. i dont think that i will loose a whole lot of performance with the change, by changing the gear ratio from 3.42 to 4.10. and the 200-250lbs. weight difference between the aluminum LS1 engine and the tall deck big block 427. i think i will just about cancel itself out perfomance wise, at least thats what im hoping for.

Well my 427 revs to the moon, I shifted it at 7300 RPM . It doesn't start pulling until 5500 rpm. It didn't have the low end of my 454, but it is a big block and it does kick you in the ***. My 427 is for sale as well.

jdmille5

yall, i love my 427 but it kind of makes it hard to drive it al the time when im getting about 8mpg. it makes a great weakend car with the 427. i drive it all around town but i cant really take off and go an hour away, on a reagular basis. so im putting the LS1 in for streetability and for fuel economy. i later plain to put a turbo on it so i can run with the big boys.

After you put it in and run the car, please post results. Now way on the 11's with a stock LS1.

I'd say about 13.0's or maybe high 12's. These cars aren't that much lighter, and the aerodynamics are much worse.
