if it aint spinning why would you wanna adjust the suspension???
Replace converter and then start all over again.




When I got the new shocks I had taken it to a suspension shop to get a weight & balance and find the CG. They tweaked it to get it where it is now. I changed the shock settings a little to what your are seeing.
Next question which is why I haven't pulled the trigger... What company for a great converter? Can I get some input for top 3? COAN, Dynamic, etc.

dont have much experience with this but i think it would be hard for any one of them to get it 100% right the first time.

If IT WERE ME---since you already have a 5500 stall converter (good, I hope) I'd first make sure I was leaving while up against the converter. I had a similiar equipped but MUCH heavier car & would 60ft in the 1.30-1.33 range. Don't know what tire pressure you're running, but we almost always ran around 9psi. one way or another I'd find some way to loosen up that front end & for that matter, later on, if you have no luck, perhaps even lighter rear springs so as to the allow the back end end to squat---it looks like your back-half isn't working either. For me, if the car "pitches", your suspension isn't working evenly which could cause or is a sign of another problem---just MY , but hey!----you asked...

Im surprised nobody mentioned rear gear. Isnt a 4.56 with 33" tires to high? I would think thats why mph is on the high side, but 60' is slower. Dont most cars with big tires run a taller gear?

Why would you want more susp travel if it aint spinning??
All other movement eccept forward will slow the 60 down.
Besides i dont know if your 60 is bad at all?
Besides pulling a little to the right, that chassie looks sorted out to me.

I was thinking of putting 4.88's when I went from 32 to 33" tires. I run 10.5 lbs of air pressure in the tires. I think this winter I'll start with a new converter, then front coil overs to get more travel in the front end and then see what happens at the track before I change anything else.

you should be turning about 7000 rpms at the line now right? Thats calculated with 8% slipp in verter.
Doesnt seem very wrong for me.
Going to 4.88 wont change much. your mph will probably go up a little more.
