Re: 62 Chevrolet, STILL No Traction

That was GREAT, RallyeBob... learned all kinds of 8 cylinder words and everything !
HEEE HEEEE !!!

Dave, Mikes car is a Super Stock... I think he has an aftermarket 4 link

BTW, I got the ride height down, and did some measurements. It's better, but no where NEAR ideal.

Re: 62 Chevrolet, STILL No Traction

I been thinking a lot about your 62 since I sent you a PM yesterday. I know guys that ran well in the day of these cars that did very little to the rear suspensions. Now I realize we have much better tires and a better clutch setup. These cars didn't seem to be so bad with a good set of tires and some shocks and maybe an airbag. It was soon realized that hard bushings and raising the mounting point of the top bar at the rear was the hot setup. Are you sure the front is working correctly. In the day everyone loosened up all the front end and the things nearly drug the rear bumper, but got weight transfer. Just some thoughts, I think you are getting there.

Traction Getting Better !

First, I'd like to thank everybody who advised me here...
I listened to all, and am applying what I am aloud to !

I must admit, I was just about ready to give up. Car has been jinxed !
EVERYTHING going wrong lately !
Have an engine miss that seems to be getting progressively worse. Concerned that it could be electrical system being over-taxed by the new "big" fuel pump, electric water pump and electric fan... with my stupid alternator not working.
Seems to still be really lean too. Don't get THAT ? Same carbs I ran before.

AS for traction, it appears that I may be getting there !
Raised the front about 3/4", and lowered rear a bit ( not enough yet ).
On cold slicks, for the first time, I felt that "jump" effect of a drag car !
FINALLY got a hint of atmosphere under the front tires.

I'm going to bring the rear down another inch. Car will still sit with some forward rake.

thanks again, people

Aubrey

Glad you're finally getting some traction.

My confusion is partly induced by terminology. I'm not an experienced drag racer.
A few drawings, indicating the fundamental desired geometry ( desired angles / measurements ), in a couple different settings... indicating what "this" setting would change. Evidentally, I can't read too well, so pictures would REALLY help !

As a result of your comments...and others similar...I've completely rearranged my site and added, on the home page, a "Getting Started" tutorial with 13 pictures. In effect, I've attempted to cram the engineering student's sophomore year onto one page!

Hope it helps.

Re: 62 Chevrolet, STILL No Traction

Maybe ( likely ? ) I'm missing something, Billy ?
The diagrams helped though.

Re: 62 Chevrolet, STILL No Traction

questions aubrey...

what did you do with the 2 piece driveshaft ??
two upper links mounted at what position and hieght??
solid bushings all ??
rear locator bar used ?? fixed or floating ??
why was ballast bolted on rear crossmember frowned upon ??
spare tire & related fixtures used in trunk ??
rear bumper original ??
rear seat in place / factory ??
front bench seat / factory ??

what class does the wagon fit with the 409 4 speed ??? THAT would be a HOOT !!!!

p.s. i get a couple inches of "atmosphere" in my u/sa wagon...
but better weight distribution helps... 1790 / 2650 = 4470

Re: 62 Chevrolet, STILL No Traction

ALL the questions, Jack !

two upper links mounted at what position and hieght??... 2 1/2" higher than the stock mount on top of housing.

solid bushings all ?? Yes

rear locator bar used ?? fixed or floating ??... Panhard bar ? ... stock... dead on.

why was ballast bolted on rear crossmember frowned upon ??... The weight ended up being below the height of the centre of gravity of the car. Actually unloaded the tires when the rear dropped down.

spare tire & related fixtures used in trunk ??... nothing. but a battery.
http://www.bruneauperformance.ca/mybelairtrunk.jpg

rear bumper original ??... completely.

rear seat in place / factory ??... removed for roll bar installation. Steel sheet fit in place, carpeted.
http://www.bruneauperformance.ca/rol...talledrear.jpg

front bench seat / factory ??... bone stock ( needs recovering ! ), positioned one notch up from furthest back.

what class does the wagon fit with the 409 4 speed ??? THAT would be a HOOT !!!!...
well, in 63, the engine I believe is rated at 410 HP ( higher lift cam profile ).
Lightest that car could be, is about 4050 pounds. So I guess E Stock.

Re: 62 Chevrolet, STILL No Traction, Aubrey

There is a guy in Atlanta that has been racing 60's Chevrolet's with 409 Plus Cubic Inch engines since day one. His Name is Lamar Walden, he is still Nostalgie racing those cars. I might can get his number if you'd like to call him!

Re: 62 Chevrolet, STILL No Traction

Woodro...Could you elaborate on the approx date of Day one ???
