I get it. I'm totally beyond my understanding, and grasping at straws at this point.

Keep at it brother, it’s a tuning game. Part of what makes it “fun”. 🤣
Also why I got out of the dedicated inline track stuff - fun, but very hard on parts and incredibly frustrating at times. I’ve since realized I get more enjoyment out of building sh*t, and having an extremely capable all around performing missile that excels at not just one thing, but does almost everything very well.

agreed x10. Some method of timing regard on the hit - MSD box or something - is my vote as well.

This thing is haulin' butt at the big end of the track. A 1.5 60' will be night and day.

Bickel tells us that if you drive the tire down too hard by way of the IC location, it tends to fold up the sidewalls, which in turn makes for poor surface contact. Opposite to this, if insufficient force is applied to the tire, it will simply spin without accelerating the race car.

How to Tune a Four-Link Suspension System

Over the years, drag racers with door cars have gone through all sorts of suspension arrangements. Lift bars, slapper bars, Super Stock springs, leaf links, ladder bars, three-links, four-links, and …

Sounds exactly like my problem. Time to dive in....
Edit: just for sh*ts and giggles, I checked the FSM and found this that contradicts the whole theory

big car heavy front wieght distribution makes it happen... thats a gorgous car bro! them are some decent #'s have fun stop beating your self up. Bracket racing is where its at dial in and make the number...
ITS a win win.

Yeah, but there's that whole "less than optimized combination" thing nagging at my brain...... must optimize, must optimize

What are you using for your 2 step?.

You've posted it before, but I can't locate the post.

The 2 step is the MSD piece. I only had a 3k chip from the 6AL but just got a 1-3k chip that I turned down to around 2k. I think the suspension changes may negate that...

Not quite as exciting as a carbed LS, but i got the rear squared up (within a 1/16") and the pinion angle set. All the adjustable pieces got shorter, so that's gotta be mo betta.

Prop Joe sent me some shocks. I set them in the middle at 40/60 after stroking them many times (to purge the air). Put the street tires on to hit a show with my buddy tomorrow.
