Chevelle suspension improvements

Hi Guys,
I usually spend most of my time in the engine area, but I was wondering if anybody had a recommendation of a type/brand of front shock that would improve stability and handling for a 67 chevelle with a BBC.(If I am driving on a country road at 60-70 mph I can bottom out the headers over kind of humpy but not rough roads) see my photo album for a pic of the car. I have replaced the springs,tie rods, ball joints,bushings (all oem unfortunately, but new). I have also swapped in the front discs/spindles from a 72 monte carlo. I am ready to swap the sway bar and shocks and would appreciate any recommendations regarding size of sway bar and ratio of shock absorber to improve this situation.

Springs

I would think you would need some stiffer springs..Try quickor.com for the sway bars..Stockcarproducts.com for the springs...

excessive bottoming is usually a spring problem..

Hey rat lover,
First off nice work done. What I would suggest is what I was thinking of doing to my car once a get some money coming back in. They make adjustable shocks. You can set the ratio to what you want or need some are 3 step others go to 10. Check out summit and look through there you should be able to find what you need. I think summit even makes shocks. I mean of course you can go from $20 to $150 a shock thats all your choice. Almost any of the name brandes should be good search around here im sure you can find every brand someone will have something to say.

Second if you wouldn't mind sharing info about your front disc brakes swap. I have wanted to do that but never was really sure if I could just pull them off something else. I'd be thankful for any details you might care to share.

Thanks,
Chris

I was afraid of the springs being the issue. I recently put in a BBC instead of the old 350 I had in there. The ride height was not affeted much by the swap, as I had replaced the old springs with a small block with a/c. The ride height was quite high with that spring. I am hoping a set of stiffer shocks may help to control all the power I am putting to the chassis. I mean, when I lay down the hammer on it and go over a couple of humps in the road, and throw in a couple of shifts and the car is jumping all over the place. I will have to do some research on my own to see what's available, would like to hear of any first hand recommendations if possible, specifically on the chevelle chassis.
As far as the spindle swap... The spindles just bolt right in. The only downside is it will increase the front wheel base slightly. This may be an improvement for overall handling, bit it will require to adjust the tie rods out about 1/2"-3/4" (approx) either side. It will take a while to get the suspension dialed in as I believe you will have to shim the upper control arm for correct caster angle. the rotors are cheap and plentiful, can be purchased new and the single piston calipers as well are very common for rebuilds and pads. Even with the single piston caliper it was a remarkable difference from the 4 wheel drum brakes! I highly recommend it.
