Hello,
My question concerns my 79 Cutlass, not my GN. I took my Cutlass racing again after making some timing adjustments, replacing the nearly bald Firestone Wildcountry 225-70R14's with BFG TA's of same size (barely used), and installing a MUCH larger front sway-bay (I autoX the car). My question is this: after the above adjustments, the car had massive wheelspin problems off the line when before I was able to do a foot brake launch right to WOT with no wheelspin WHATSOEVER. Best 60' before: 2.33, after: 2.68 (still spinning). This at the same track under similar weather conditions.
The car has an OPEN
2.73 diff behind a mostly stock '73 Old's 350 (intake, carb and HEI). I'm having a hard time believing just the timing could make that much difference, any thoughts on the tires/sway bar?
Oh, I also installed new Gabriel VST shocks (the old ones were TRASHED when I took them out).
