What's the pinion angle and whatever that # is, are you 110% sure you have measured it correctly?

So , whats your suggestion on pinion angle?
BTW , what are the best 60's from the AMX? For comparison.....do tell.......

There is no comparison as my car has a Cal-Track (bars & springs) set-up with AFCO shocks and 9" wide slicks. But with a 634 HP SS engine it had consistent 1.38 60' times, best ET was 10.02 @ 133 in SS/H @ 3160 minimum. Pinion angle was 5*. And then we found out what was wrong with the chassis and it's been parked since.

I have run ladder bar cars with coil-over shocks and 11.5 wide slicks and would suggest a minimum of 5* to 6* pinion angle. Yes I know, that's 1* to 2* more than most would say. But I've never had a car with traction problems.
But that means I've never had enough HP...

There's a video of my car on YouTube. Rob Youngblood saw it and noticed I had too much line-lock pressure as I was having to force the car to the final stage light. I was running 250#'s. He suggested 100-150#'s as bumping it in like I was tears up the clutch. I took his suggestion and it worked a lot better.
There's a lot of good advice here and just like building a S/SS engine and car, all those little things do ad up. It's the guy's that poo-poo little ideas that never really have a lot to show in the end. And wonder why the guy in the other lane is so much faster.

New engine was supposed to be on the dyno two days ago but as usual, the shop has something ahead of me. Once that's done, fix the chassis. The driver side floor at front leaf spring mount was pushed up the rocker panel.
Adding Calvert single wheelie bar and fix this and that and go racing. But today it's 112* outside so motivation to work outside is super low!
