Hi All -
Before I get flamed, I've already scrubbed the site and I'm citing the last conversation I referenced on this topic at the bottom.
Since I was a kid, all I wanted was a light to light car that would light 'em up and do reasonable burnouts on demand. It's a '68 300 with a Blueprint 355 (375hp, alum heads, etc), 700r4, and pretty much everything out back is new. Still the original 10 bolt, but new 373 gears (Yukon posi, Richmond ring gear), new boxed lowers (square channel, not modified stamped steel), new adjustable uppers, new bushings, new springs and shocks, and a swaybar. Control arms have heim joints in the front, upper bushings I guess are rubber. They're 'red' vs black, but seem softer than I would expect urethane to be.
I'm currently going for a day two, 70's street machine vibe. I'm running Cooper Cobra, 235/60/15 & 275/60/15 on Torque Thrusts. The new springs are wagon springs and about 2.5" taller than the stock ones and set the stance perfectly (IMO) and allowed me to ditch the air shocks. I'm not part of the low and tuck crowd, I like it tall. That said, I'm posting now because I can't seem to get rid of the wheel hop. With the car leveled on stands, I've got -4* at the tailshaft and balancer (checked both to be sure) and I set the pinion to -1*, so total is -5*, right? Is that too much? As long as it's not allowing positive rotation over 0 under torque it should be fine, right? I don't understand why it's still hopping. What am I missing? HELP!!
