I picked up a set of 74200 Moroso springs used real cheap. 4.8 dia I hope they will fit... It looks like the will. I’m running a pair of stock spring that have been cut to lower the truck. Compressed they are 7.75 tall and if I remember right they are around 12" tall uncompressed. My truck will not transfer for anything. if it doesn’t dead hook and you have to lift it becomes a pedal fest...This thread has been a ton of help. It all makes sense now. Thanks guys

Got the new body mounting bushings installed today. Still waiting on the headers and exhaust to get back from airborn coatings they are saying Friday! Man I hope so I'm dying to try it out!

What headers and motor mounts do you have?

solid moroso engine mounts and custom built headers. I hear that some of the members are running a bbc chevelle header. I was running a poly engine mount and super comp hooker headers but after installing the solid engine mounts the headers hung to low draging all the time so I built a custom set of fenderwell headers.

Ok guys I ran the truck this pass weekend at ctc and it seems to be moving around alot
front to rear side to side any input?

Re: need help with my suspension 1970 gmc
 

Moving around? off the line ... on the big end?

Re: need help with my suspension 1970 gmc
 

Front to rear when taking off and rear to front when stopping. A friend of mine was following me and said when I took a turn it looked like the front tire almost come off the ground. It has alot of movement in the suspension.

Re: need help with my suspension 1970 gmc
 

So, is it tranfering weight then to the rear under acceleration and then tranfering it to the front under braking? Not sure I follow.

Is it moving weight to the outer front in a corner and lifting the inner rear?
