59 Chevy rear suspension

I got a 59 Chevy longbed that I'd like to turn into a respectable road racer. I originally planned on installing a triagulated 4-link. I've read a few posts on this forum and others of people having problems with this setup, specifically in higher horsepower applications. I plan on eventually installing a 600hp+ 454ci.

Is this suspension design prone to having problems in high horsepower vehicles?

I know that a typical parellel 4-link runs a panhard rod and the idea is to keep the panhard rod as long as possible to provide the best side-to-side axle stability. Do the shorter upper arms used in a triangulated 4-link cause stability problems?

I'd appreciate any advice/information I can get of this system.
Thanks
Robert

Not meaning any disrespect to you at all, but what makes you think that this truck will ever be a "respectable road racer"?

Techinspector,

I understand that being an older larger pickup I may never be able to hold my own against a well built Camaro/Mustang or a newer rice rocket but that doesn't mean I can't try. I refuse to limit myself based on the popular opinion that a pickup can't handle. I would much rather be limited by a light back end and heavy frame then have a crummy suspension limit me.

Please don't think I'm mad while writing this reply. I'm not at all upset and I appreciate the constructive criticism.

There's nothing inherently troublesome with the triangulated 4link. Personally, however, I consider the design to be in violation of the KISS principle.

For your application, I would recommend something similar to the '05 Mustang rear suspension: 3 trailing links with a Panhard. The last successful world class sports/racing car with a beam rear axle was the early Jaguar C-Type, which used this same setup, but with the single upper link offset to the right to dynamically cancel driveshaft torque effects.

As for the handling problems, you will, of course, have to "put it in the weeds." This is complicated by the long wheelbase. The other problem is the weight bias. You'll always be at a disadvantage to a car having a more equal weight distribution. An Indy car has a comparable weight bias, but reversed. Compensation there is with larger rear tires and aerodynamic loading. If you're limiting yourself to autocross events, you can't do much with the aero, but you might consider the larger front wheels and tires. Of course, you're still chasing your tail, since...if you had a 50/50 distribution...you could run the better tires on all four corners! Basically, you're going to be running a lot of rear roll stiffness to keep it from pushing in the corners. As for choosing spring rates, I'd recommend the guidelines in a good suspension book like Race Car Vehicle Dynamics.

Billy,

Thanks for the advice. I certainly have some research to do and some decisions to make.
