Re: chevelle suspension questions
 

50 is better than 0:). It is a good start. I probably started with 50 when I was trying to be convinced to put some ballast in. I run 140 lbs. now and have had as much as 190 with the bigger 460 BBC I run now. But 140 seems to be about right for me. Put 50 in and see what it does.

8" rim is ok with those tires. I always ran mine on 8" rims and run my 9" hoosier radial slicks on 8" as well. I'm sure a 10" rim would be better. Just wanted to make sure you didn't have them on a 7". The worst thing is too wide a tire on too narrow a rim.

Good luck.

What are you guys using to get 150 lbs of ballast?

Re: chevelle suspension questions
 

I went to a metal scrap yard and they had big chunks of metal that had been cut up with their big scrap metal shear. Got 4 pieces (3 were 50 lbs each and 1 that was 25 lbs). I can't really remember what I paid but I think they charged me about $50-$75 for it all which was a lot cheaper than lead and easier to work with as far as mounting. I used 2 pieces of it and welded straps to it to bolt to trunk floor. These 2 chunks are at rear of trunk. Then in front of cell I used a 40 lb dumbell with a strap welded around the handle and bolted to floor. I think going strictly by the rules it should be bolted to the chassis but I use large fender washers and grade 8 bolts to make sure it stays put. Got another chunk made up that can go to left of cell when I need it.

I have never put weight in my chevelle. There are lots of rear suspension kits out there that will work sway bar antia roll bar a must, Untilll you free up up front end and gain travel you wont be happy. Take a look at tony janes car the red 68 lower body line and spindle and how it leaves. Iam only going 10.50s yet hook good. Trick springs are great yet Ihave 6cyl wagon spring cut 1coil plus 60 mil. Ball joint selection is key here along with control arm bushings. That said have 4 wheel alinment done by frame shop. Good luck:)
