Where did I go wrong?

[mariojb]

So I finished installing my CPP lowering components on my '71 last night and took it for a spin. It's whining on acceleration and cruising and stops when I let off the gas as I approach a stop. Didn't get over 30 as I was on residential streets so I don't know if there is vibration as well (pinion angle off?). What did I do wrong? I installed 2.5" dropped spindles/2" springs in the front and 2" dropped blocks/4" springs in the rear.

Shorten the drive shaft...damn, I didn't account for that. would a lesser drop, say 1.5" or 1" not require shortening the shaft?

sounds like a big pain...

It's not too big of a pain, nor very expensive. Took mine to these guys about a year ago, they shortened it, painted it, swapped my Ujoints, all in a little over an hour and for about $100.
