Yes, the driveline angles are off and the cause I think. Post up here with any recommends please.

Good luck with the 12.4's. I think you do it... No sweat. Its all in the details now with our setups. The .1's come a lot harder and will be as easy to go the wrong way.

 

you can shim between the axle and leaf spring if you have an angle finder gauge.

 

Bill, you don't have your 1/8th mile times? And aren't you running the GT2-3 cam instead of the GT7 as KY? I don't know, maybe short end/bottom end difference. What I'd like to see is scans of the 1/4's compared. That would be tell all IMO.

It's nice to see all of the hard work payoff KY, glad to see leveling it off and doing the things you did help her grab and go. Maybe...off topic...all that grab and go force is exactly what you think, hard on the stock leafs. Get some caltracs and be done with it!

 

No, they didn't print out on that run... Yes on the cam.

 

My times are even more weird. 12.50@111. I have trapped 114.4mph in the 1/4.

I dynoed 25hp less than Bill as well. I dont know, except that Bills 5.3 runs super hard for a 5.3. Almost the same as my 6.0 lq4 with the same mods.

 

dont know but for being 4wd's, ya'll got them pigs moving!!

 

That is some serious MPH. I wish I understood track dynamics more. I don't understand the mph/et thing.

I agree, Bills truck is a beast. I know I would never have gotten to his level of performance with my 5.3. Course he does have access to arguably one of the best tuners in the country.

 

Ah, you guys are embarrasing me

Rick is a hell of a great tuner, and his shop top notch. He has spent a lot of time tweaking my tune on the dyno and the street.

 

I have a cheapo gauge and have them all measured and a couple options planned to get them at least equal. You wouldn't happen to know what trans, shaft and pinion angle is on a stocker would you?
