I have a 67 chevelle ss396 and am rebuilding it from scratch. I'm running a zz502/635 hp/ 625 lbs torque. I want to use the stock front lower control arms but want to install upper tubular control arms. Does anyone know if this is a good idea? If so then what is a decent manufacturer of tube control arms
without selling my wife to get them. I would also like to know if the poly graphite bushings are any good on the front end and rear end. I've heard and read both good and bad on them. Some say don't use them as they will bind and squeek while others say they are wonderful and outlast anything else. I don't want to go with the bushings that need to be lubed unless I absolutely have to. I also want to change the trailing arms on the rear end and add coil over shocks ( I already bought QA1 c/over shocks). So if anyone can steer me in the right direction of suspension with trailing arms I would appreciate it.
The car is going to be used for street/show and sometimes strip but mostly street and show.
Any and all info is greatly appreciated and if anyone can add to this or suggest other ideas that's great too.
Thanks a lot.

There`s not a thing wrong with running tubular upper arms and stock lower ones. Current tubular lower arms offer no geometry improvement anyway.
I`m not a big fan of poly for suspension bushings. I`ve installed plenty of them over the years and in my experience they ALL squeak sooner or later. They`ve also got stickage and non linear binding issues under load. Lastly they can and do cold flow (letting holes egg shape). Stick with rubber or upgrade to delrin or (in upper arms) greasable steel. If you`re not into greasing bushings high durometer rubber would be your #1 choice.
Good manufacturer of tubular upper arms? Heh, I`m a little biased there. We do have them with high durometer rubber bushings BTW. :thumbsup:
For rear trailing arms IMO Currectrac are THE way to go. They`re the only arms that use a greasable spherical joint on one end to eliminate non linear binding. Yes,you`ll have to grease them every year or so but it`s worth it.
Adding coilovers to the rear is tricky to do right. You can`t just bolt them to the original shock mounts. Alston/Chassisworks makes a nice setup with it`s own tubular upper crossmember and adj. axle mounts. It requires some welding but any good kit will. It usually includes Alston adj. Varishocks which look similar to your QA1s but are a step up in quality. FWIW the kit is on sale this month. It can be had without the shocks if you already have the right length but the sale price wouldn`t apply. Mark SC&C

thanks a lot for your help. you have given me a lot of insight now and it's greatly appreciated. I forgot to add a concern of mine when I placed this query and that is what about front and rear sway bars? Any idea as to should I add them and who makes good sway bars. It seems you can find them anywhere and costs vary from a hundred to several hundred dollars.
Really confused on this one.
Thanks again.
