@ guitar jones....Your saying your running a 4 link? With all due respect to the picture of your car,your car leaves really ugly. I admire the numbers you are putting down though with your small block.
Lots of my friends have ran 4 links, and they were lost with them for a while.Some even found the sweet spot, then lost it.
I ran a back 1/2 ladder bar in my Duster for years,It wheelied about the same as my Valiant with Cal Tracs, and it was deadly consistant, took me to many wins.
I then had a 2200 'glass Chris Alston 85 Daytona with a 4 link, and although it ran the number, the traction was sub part, at no more then 8 different tracks.That was with 15"x14"x32's on it. I also ran 2 sets of MT's and 1 set hoosiers.I admit, I was only running about 550 H.P. which was too mild for that car.
If you look at what Steve said, he has the issue worked out. I got a lot of info from his experience.
In my humble opinion, 4 links are for big horse power, big C.I. cars.And if you have lots of time to test and tune, then you may get lucky and figure them out.For me, I want to go rounds.

P.S The second photo of the Duster is the same car later, only cosmetic changes, and yes, that is all BLACK TOP drag strip including the starting line, it was a converted air field at Silverwood Park in Idaho.So to me, the ladder bar was working just fine, and yes, I won 3 races there, and was runner up once.
