12.2@115 in the 1/4 mi.

Was just thinking how fast that was, back in the 1990s... How fast is/was your GTA?

This was on 245 width BFGoodrich tires, FWIW...

Thanks. It was naturally aspirated, no power adders. Just a good 'ol 6.3L
  • When stock, she ran 14.3 @ 96
  • A few mods - cold air inlet, flowmaster muffler, underdrive pulley, and performance resource chip, she ran 13.9@101
  • With AFR Cylinder heads, Superram, 58mm tb, she ran 13.1@109
  • Changing to the 6.3L from the 5.7L, she went down to 12.2@115 mph
