This site,http://www.raceglides.com.au/TechInfo.htm, is the best explaination yet for understanding our suspensions. Thanks Bommer 67 for listing it on another post. After reading it several times it agrees with what Dick Miller, Dave Morgan and other have been saying for years. Alf Weibe is an exception as he works on a complete different theroy.
I have thought for a while that an instant center 5" or so off the ground and maybe 30 to 36 infront of the axle might be close to the sweet spot on my car. As it is with the upper bar in the lowest hole of my morrison no hops it provides too much anti squat.
Anyway, it has got me thinking again about building brackets to lower the front mount of the lower control bar to allow for the IC to be set lower and adjusted forward or backward along a line parrallel to the ground.The adjustment would then be made with the upper control bar mounts @ the diff. housing using the various holes in no hops like Morrison's.
Has anyone tried this approach? This would begin to mimick a 4 link set up's adjustability.
Food for thought.

No I haven't tried anything like that, but that is how my ladder bars are. They are 32 inch bars pointing down at a 5 degree angle. I'm not sure how far off the ground they are but the IC or front mounting point of the ladder bar falls in what you believe is the sweet spot.

There was a 66 GTO @ the races two weeks ago which was mini tubed so it had 12.5 tires under it. It ran Morrison Ladder bars and the front connection was 8" or so behind the front seat and pretty low. Wow, that thing hooked great. It was running low 1.30's 60' times and carried the front tires about 10" off the ground for a long ways. I'm sure the tires helped but I was impressed.
