88 427 Camaro

Here is the video

www.koolmeister.com/776b.mpg

of my last pass this year. It is a 7.76 @ 94 with a 1.72 60 ft. This is with entirely stock 2.8 liter suspension, a 2400 converter, foot braked (off of idle), 26x10 slicks, 3.73 gears, a full single 3in exhaust and the same jets in the carb as when it came off the dyno (read very rich now with exhaust).

Before the 3.73 gears, I was running 3.27's with a 28x9 slick and the best 60 ft then was also 1.72.

I have also gone 1.88 best (normally 1.90-1.95) 60ft with BFG touring ta's (standard 8 inch wide street tires, not drag radials) on the same setup.

What am I trying to say? I don't know, maybe, do you really need a $1000+ worth of suspension parts to hook a street car? With slicks, I leave off of idle to WOT without spinning the tires.

Nice video... how fst was that truck?

You have walked onto the biggest baddest dog porch and you will be dealt with accordingly.

I'd rather be historically accurate than politically correct!

Basett_Racing

That's actually a complex question. I noticed that your 1/8 mile MPH was 94, which was what my best run was. Now granted, I have a 4000RPM convertor as opposed to your 2400RPM, but you do have TQ of a Big Block. I have tubular LCA's, Panhard rod, and Torque Arm, all of which I made at work. I have Spohn LCA Relocation Brackets, and an Air Lift airbag in the right rear. I have '86 V6 springs front/rear and a 87 IROC "wonderbar" and no sway bar on front. I now have Lakewood 90/10's front, and Competition Engineering 3-way adjustable rear shocks, but I haven't run since I put on the shocks/struts. So do you need a lot of suspension mods to make a street car leave without spinning??, No. But, if you want the best possible 60' ft times with a given amount of HP, then suspension, weight and convertor stall speed are about the only ways to get it. I picked over a tenth in 60' times going with the tubular LCA's, TQ Arm, and LCA Relocation Brackets alone, So I'm a believer in a good suspension. I was running a best of a 1.86 60' time with my old engine(#882 headed 350), and picked up to a 1.74 60' just with the tubular stuff and Relocation brackets. I ended up going 7.84 @ 88.21 in 1/8 , 12.52 @ 106.55 in 1/4 w/ the 1.74 60' with my old 350. As far as my car goes, I can't go any higher on stall RPM and still drive it. I do plan to take out the front/rear inner impact bumpers and the door impact beams, but I am going to retain a full interior including rear seats and my CD player (don't worry, I don't have a "system", just the (2) dash speakers and (2) 6 X 9's) but I think I can get at least 150# more pounds off the car, making my race weight around 3160#. Other than that, I am planning a cam change and putting a NOS plate system on the car next year.

I don't mean to come off as being a smart A$$ or anything, I'm just simply stating that with a little suspension work, your car would be significantly more impressive than it already is. Here's an actual shot of the run when I pulled the 1.59 60' ft time. Even though it is a terrible, dark photo, you can tell the car is leaving with driver's side tire 6" - 8" off the ground. I can't wait to go back in the spring, with car weighing 150# or so less in that cool, clean air!!

Nice run Miles, that BB sure gets off the line strong!

Did you red light? Have you tried power braking your start, like rev to 1000-1200 rpm then go?

Nice car!

As a comparison I'm looking at one of my time slips from back in mid September. 3800 stall converter, 28" tires and 4.10 gears, 3200+ pound car with driver. Don't forget that these are also at altitude. The density altitude that day was hovering around 5200 feet.

60 foot: 1.607
1/8 mile: 7.375
MPH: 94.72

I don't know how much the MPH shows at the 1/8 mile as a good HP but it should show a close enough comparison. That first 1/8 mile is all gearing and shift points. The last 1/8 mile is brute HP pulling the car to the finish line so the 1/4 mile MPH is a good indication of HP.

Since I have the lower 60 foot time, it shows in the 1/8 mile ET regardless of the MPH.

Good suspension is important. It may lower your ET a bit but the main thing is consistancy. A car that gets 1.70 to 1.80 60 foot times isn't very consistant. That much of a difference at the 60 foot mark will make a big difference at the finish line. Good suspension makes that window smaller and makes a car easier to dial in.

When I'm done with the winter projects I hope to have consistent mid to low 1.5 60 foot times and with the transbrake I should have no problems yanking the front wheels off the ground

A properly setup suspension and chassis should yank both front wheels off the ground at the same height. If only the left front one comes off then the car is twisting too much so there's always room for more improvement.

Red light, yep
Power braking = 1.8 60 ft.
It's got the mph to run mid to low 7's, just not the converter (2400). Going to try a 10in (3400) this spring.

That'll wake it up.

My current converter is a JW Sportsman. It's a loose 10" that's rated at 3800 but isn't recommended for transbrakes, NOS or over 500HP. Compared to others it's a good converter for the price.

Since I'm going to be using a transbrake next year I'm getting their loosest 10" competition converter. It's supposed to be around 4200 stall. I don't need a tight 8" or 9" since I want a softer hit with the converter and don't need a 5500 stall.

JW's web site is http://auto2000.com/jw

The Sportsman converter is listed at $300 US. I paid $400 Canadian for mine so dealers are probably selling it for less than the suggested list price in the US also.

The convertor I'm using is made by ACC (Alabama Convertor Corporation), and it is a 4000-4200 convertor. It flashes about 4200-4300 behind my 383 (It only got 3900 with the old 350) and it is a pretty loose convertor. I know this company is not widely known in other parts of country - or continent, Stephen - but they have a damn good convertor for the money. I know over a half dozen guys using these in 7 sec+ (1/8 mile) bracket cars and street cars. I got mine from Bowtie Performance Headquarters
and was $285 + S/H. I just thought I might pass that along. Their smaller convertors 3500-below are all under $200, check 'em out.

Miles, Thats a good run. I saw a lot in your video that was similar to my car running. With 3:73's and slicks I would spin through the 60ft mark of course thats also because of heavy rubber already laid out on the track. I went back to 3:42's and without the heavy suspension mods the problems is solved. Have you considered droping down the ratio a bit a BBC that isnt going to get alot of suspension work done isnt going to need that steep of a gear IMO. Ehh but what does a small block guy know anyway

Oh BTW if you do know anything about that truck running next to you do post it. That guy looked like he would have taken you if you dident RL. As a truck guy Im curious.

Update on my converter.

I just purchased an 8". Not sure where it will actually stall. At our higher altitude I'm guessing it'll stall around 5000.

The 10" I wanted wouldn't have been able to stand more than a 3000 rpm launch from the transbrake.

I'm going to have to watch that video some day and see what everyone is talking about with the truch

Looks like a fun truck also. Does your brother run on the street at all? Bet if he does he embarrasses alot of mustangs also.
Heres a link to my truck before I reworked the top end http://albums.photopoint.com/j/ViewP...p=52415529&f=0
Amazing though it was running 12's with a 50 shot. Now it runs 12's without N20.
I hope to get the camaro into the 12's this year.

Oh yes. He drives it quite regularly. His best ET (the 12.43 -1/4, 7.86 -1/8) was on 28 X 12.50 ET Streets. The engine is only 9.8:1 and runs well on pump gas. He's also only running a 3000RPM B&M Torkmaster stall, so it is very streetable. The Sportsman II heads, and the solid cam are really the only reason it runs as well as it does. He has surprised many Mustangs and even several 4th Gen LS1's on the street and the track. There's a pic of him wearing out a 2000 Z28 @ Reynolds, Ga. on our site. His truck weighs 3665# w/o him in it. Have you ever weighed your's, and how much did it weigh?? What have you done, if anything, to reduce the weight?? We are planning on putting it on a "Go-Fast" diet when we change engines in the spring, and we are trying to get an idea of what it might weigh. Thanks.

This was a 7.96 -1/8, 12.55 - 1/4 run @ Montgomery this summer.

I havent had it weighed as of recent, I did it 5 years ago but dont remember what it was. I think Im going to visit the rock and sand place in a few days to do so. This one was restored to show quality but when its your only ride that goes fast I know there is a guy in town with a 74 short box that has his truck down to 3000 even and runs 12's also, but he has some serious suspension mods done and lead weights in the box. He's got a fiberglass front end, hood fenders, and the cheap jap replacement doors that weigh almost nothing compared to the good old gm ones, oh and he took out the piece of the box near the cab and has an x bar holding the box togather.

TO 427 HOW MUCH POWER DO YOU HAVE TO THE WHEELS? MY CAR IS IN THE SIG IVE BEEN TOLD 350 AT THE WHEELS. BUT I GO 117 CONSISTANT AND 93 IN THE 1/8 WITH ONLY A 2800 STALL WITH A TURBO 400 AND 9 INCH REAR. MY CAR IS 3565 WITH ME IN IT. LET ME KNOW WHAT U GUYS THINK!!!!!!!

AlkyIROC

Well a 3565 pound car running 117.0 in the 1/4 mile based on the power to weight ratio is pushing 445hp to the rear wheels.

If there was any kind of a tail wind then the calculations are over the correct results.

What gears are in the diff and how tall are the rear tires?

Personally I think your car must be a lot lighter than 3565 to run that quick. My old 383 that blew up last year ran consistant 117 mph but the car was also less than 3100 pounds with me in it. 3.27 gears, 26" tall tire and 3800 stall converter in a TH350. Everyone kept asking where my NOS bottle was because the combination looked like it shouldn't have run so well. I also had some heavily ported, large valve camel heads and a solid cam with about .550 lift.

88 427 Camaro

I agree with Stephen. Either you have a lot more hp than you think or your car is much lighter than you think based on those times. I have only had mine on an engine dyno and it made 500hp. It is on my web page if you want to see it.
