Finally got my car to the strip. Ran a best 13.16 at 103mph. Considering I only had three passes I will take it. Hoping to get into the mid 12's with some fine tuning.

 

Pretty darn good. You could easily tear up the "built" Camaros and Mustangs that run high 14s and low 15s.

 

Not saying the times are not respectable but don't get his hopes up for beating up on built late model performance cars. Many 98-02 Fbodies ran high 12's stone stock and there are many "built" ones running around with exhaust ,cam and a little giggle gas well into the 11's and that not counting the guys that are serious. My 98 was running 11.0's times with heads, cam and a little suspension with no power adders and no weight reduction. That car was already at 97mph at the 1/8 mile mark.

 

Hello, Whats your 60' times? 13:18 is about right for 103 mph. work on the 60 ft. times and u "might" hit 13 flat. good luck, Ken

 

That's a very respectable time, too cool.

The new stuff may be faster out of the box but Confucius say,
"More important to be coolest, than to be fastest"

In '74 we would be celebrating all night if we got into the 13's.

I know about those "built" cars running around with a Cherry Bomb and 3 inch exhaust tip from Wal-Mart. Bolt on goodies everywhere, mail order catalog cars.
They put out tons of rpm's, scream like crazy and don't go anywhere. I've driven a few and it feels like the trannie or clutch is slipping constantly.

Those chrome exhaust tips do make some super tricked out cold air intake tubing.

 

There is a guy around here that has a mid 70's cutlass and the last time I was at the track he was running in the 8's. Of course he does have a full blown 502 in it

 

He probably had the motor in his Chebby, but was lost in the crowd so he put it in something to give him some attention......

 

That was not an issue last night as I never lost to a one of them cars. Of course I raced them from a roll which produced minimum tire slip. After it gets rolling it is all over for the them. Actually beat a new corvette last night. Boy was he ticked. Anyways I have will have to work on my traction problem. Them 455's just pull and pull.

 

I remember when I took my first 12 second pass I was in heaven.........When I hit my first 11 it was just as good.........Remember the small things all add up to faster ETs..............Jerr

 

you always have to consider the driver,too.

i dusted a late model Vette in my old 13 second Cutlass at Bristol,i holeshotted the crap out of him.

but he flew by me after the line

 

To me that seems a little slow for a 500 hp car. A little disapointed in the time. Seems like witht that much torque and hp I would have been flying to the finish.

 

500 hp?you should be flying.

i was running low 13's with a $500 G headed 455 in a pig 72 ragtop,i bet that thing wouldnt have dynoed over 250.

 

If you have 500HP you have more HP than I do...........You must have some sort of issues then,I didnt see any engine specs................Jerr

 

Your MPH will gives you an indication of the HP the car is making. Everthing is relative, meaning, weight, 60' time, yada, yada. so, the 103 mph is about right for 13:18 sec's. If u could get a 1.7 second or lower, 60' time u "may" hit 12:99. I don't think your near 500 hp. Good Luck, Ken

 

Will be at Milan again wednesday for test and tune. Have fixed the accelerator pump issue. It was torn. I guess the Ethanol is tough on them. Pinks is coming to Detroit next weekend and I decide to enter. I am sure I will not last long but it should be fun.

 

Maybe not on the HP . I have edelbrock heads, 40 over, 10.5 to 1, headers, a 750 edelbrock, 3.42 gears. Anyways it has never been dynoed and it has 800 miles on it. I just figured with all that torque I would be freight training the last 1/8th mile which it does but apparently not enough.

 

Well, you never know, your time bracket could be what they will pick to run all out. Good luck with that, I'm jealous!

 

You're comparing a MUCH MORE aerodynamic vehicle to a bricks aerodynamics.

A 500hp LS1 4th Gen Camaro would probably be in the 11's.
I already know getting a fast ET out of these classic Olds isn't going to be the goal.

BINGO!!!!!!

My Suzuki Hayabusa has magazine claims of high 9's bone stock in the 1/4
and I can't even touch that. So it has ALOT to do with the driver, track
conditions, weather, etc etc.

Lets face it......these cars are shaped like bricks......

 

sounds like youre running out of fuel,or you have too much cam for 342 gears

what is your cam profile and rpm at the end of your run?

what rpm are you shifting at?

 

Not saying they are not. My comment was because someone above said a 13 sec car would be taking down"built" Fbodies and mustangs. Mine made 404hp to the tires with 1.56 60ft on small drag radials and was a sneeze away from being a 10 sec car. Mine was nothing special and no where near the fastest around.

 

the cam is a clevite int lift .496 exh .520 lift int duratin 224 exh duration 234. I am shifting at 5000 . Specs say thats where I make torque.
I have been shifting at 5000. Still need some seat time in the car. I have only had three pass's. Had a flat spot when I ran . Changed carbs and have fixed that problem. Saw a video on Horse power through you tube and they chaged the springs for the advance in the distributor to a lighter spring and moved the carb to a 850cfm. Same motor as mine and they got 455 hp. Mine is balanced and my compresion is 10.5 to 1 vs there 9.5 to 1. The torque is what I am after and it has plenty. I just need to fine tune it with a little help to max it out performance wise.

 

Well the olds cutlass supreme 72 is about the nicest brick I have ever seen. lol!!! Forget the nines or 11 second cars. I will never get there without a blower. Alls I am saying is I figure I should have more top end brick or no brick.
I am looking for help to get there.

 

Do you have any other info? What is your 1/8th mile time etc, We could determine how well your run went. It can take a while to dial a car in. My Olds dropped .5 seconds when I managed to pull out a good run. 342 gears just don't cut it at the track. Especially with a 4 speed. You probably have closer to 400 hp at the crank but with gears and a little homework you'll get into the 12's
If you don't power shift the car it can be from .05 to .1 loss per shift

 

3.90 gears
850 carb
cold air to the carb. block off engine compartment hot air, use outside air
open headers

What tires are you using?

Gene

 

I'm thinking the 850 might be a little big. I had a 750 double pumper on my 455 and i swear I picked up HP by going to a good quadrajet. With the Holley I could get the street tires to stick at a 20mph punch but with the quadrajet the tires go up in smoke with ease.

 

First pass was .068 rt 2.183 60ft at 13.38 et second was .2850 reaction and 1.972 60ft running 13.16 et. The other run was a 13.8 and I hit the rev limiter.
the carb a Edelbrock had a bad acelerator pump or flat spot. I believe that might have something to do with my time. I had another carb same edelbrock and there is know flat spot. Will be taking to the track Wednesday for test and tune before the big pinks event this coming weekend which i am entered in. Like to get the car at least consistent for the pinks event. Also running MT et street slicks.

 

I had my motor done by D&S Motor city muscle and after they test drove the car they basically told me to go get the Rochester. Mind you the car seemed to run good saturday night with a good acelerator pump with 750 edelbrock, but They were saying 25 hp more with the rochester. Mind you I am not knocking Edelbrock or Holley.

 

I would not use an Edelbrock on anything I cared about going fast with. They make good steet carbs but Holley or prepped Qjet is the only way to fly if you are looking for ET. Since you do have good tires you are leaving a lot on the table in your 60ft. Is is spinning or is it just not going anywhere. That car should be in the 1.7x 60ft at least.

 

this is your recipe right here.

shifting at 5 grand,i bet youre going through the traps at 4500-4700 at the most

crack the whip at 5500,it's not going to blow up.

i was shifting at 5800,that pos lasted 2 whole years.

 

That sounds like the ticket. shift at 5800 and go rochester. Got to start somewhere.

thanks all.

 

BTT update? I like the bigger carb idea,Iam running a 850dp with my stuff and bump that shift up to 5500 like was said,maybe a litttle steeper gear...............Jerr

 

Your engine probably makes about 400 HP at the crank.

The ET sounds about right.

 

Everybody buys into the belief that what these "manuFACTures say is true. 10.5 compression pistons are usually 9.6 unless u have zero deck height and a thin gasket and and the correct CC sized heads that they base thier "claim" on. Being .040 over is a little over 6 cu in. The Edelbrock heads are around 70lbs lighter than iron ones. They are an improvement over stock heads but may not be as much as u think. That cam profile has been around a long time, it is an OK cam. I have that cam in a car I put together of odds & ends that I had laying around A white g-body, I call it "White Trash." It is a 403 with stock small valved-one angled #5 heads. Same cam but 3:73 gears. It ran 12:96 @ 105.85 miles per hour with 1:8 sixty ft. I always thought it was 360 HP at the flywheel. The heads were/are holding it back. You have to decide if u want a more street car or a more strip car. 3:42 is a nice street gear but not the ticket for the strip, plus u will need a higher stall converter to get better 60 foot times that are very important. You should talk to one of the Olds Guru's about a more modern cam profile. Leaving the heads & block intack(change cam possibly intake) you should be able to get into the low 12or high 11's but it is all about money. The next step will be a "few" thousand dollars or more. Good luck, Ken
