Video of a pass from last nights track run.

As far as the wobble, lots of ideas:
-Mismatched tires as several have mentioned
-Wide ass 275s up front and all that weight shifting to them after the traps. With tight, working correctly, power steering it takes very little to jog back and forth
-Front shocks age/brand/adjustable with all that force coming down also
-Brakes, one side pulling slightly more than the other, and then they might start to fight back and forth giving you a left to right to left action
-Grooved decel area after the traps?
-Alignment tolerances. Caster?
-Worn ball joints/tie-rod ends/etc.
-Worn wheel bearings

Just ideas there, not saying you don't take care of your car. Heck I didn't know my 2007 Ram upper balljoints were bad until a few weeks ago with it in the air.

Agree with Badhawk on the stall. That's why we were talking a trade before

With a 396 and mods I would definitely go to the 28" rears.

What is the weight of your car ?

I've never actually weighed it… but it's a full weight 96 F-body, minus the usual deletes, including the A/C, which I don't mind telling ya, I miss A LOT! and the front anti-sway bar.

I think 513's is to much gear and your shifting out of your power band to early.

Well It's hard to argue with the shifting too early thing. 'Cause that is definitely the case, in everything except WOT… I am hoping that I could extend the WOT shifts out a bit through tuning.

What rpm are you going through the traps at ?

She shifts into fourth (OD) just before the trap.

I think your car should definitely have a 28in tire with those gears and a 4000 + stall.

Again that strikes right at where I am sensing it…

Oh I should ask 1/8 mile or 1/4 car I could see having more gear for a 1/8th mile track.

1/8th mile…

My car is a 383ci has 4.30 gears 28in tires and around a 4200 stall and works pretty well.

That thing is NASTY…

Try running in D then it won't shift into OD, and may give you some different shifts as well. I run in D in the 1/4. I have heard some people's runs better in Drive and some in ODrive.

Ok heavy cars like more gear to get them rolling.

You can a bit but with a 3.08 first gear in your tranny 5.13's is still a lot of gear definitely need more tire.

1/8th mile…

The car should never shift in to OD that is killing ET not to mention the trans won't last either. I would start with tires first that should keep you from going into OD then look at getting a different stall.

Thanks, I love my Circle D converter thing hits like a sledgehammer.

sounds great man...

Besides the tires and tune to address the 60' issues and running rich, I would imagine your head's may not be letting that thing breathe up top. 195s are small for a decently cammed 396 at high RPMs, but without a dyno graph we can't know for sure.

Does anyone know a Dyno tuner who is solid in the 4th gens in Florida?

Not sure if they still do LT1 stuff, but I had mine tuned at Next Level Performance in Orlando a few years back. It was around $500 bucks, but they had the car for hours and did part throttle, idle, and drivability tuning as well...not just WOT.

They have really moved away from LT1s though, and don't advertise for them any more so not sure if they have the stuff to tune them.

[OVA1]

Yeah man, I've called them twice and can't get a return on the call.
