My best back in the late 1990s was 10.48 dont't remember mph. 1.45 60' and 6.65 1/8 mile. That was a .60 over 440 with 452 heads, 727 trans, 29 x 10.5 slicks. Completely stock suspension front and rear in my 68 Roadrunner at 3440# with me in it. That was motor only. Went 6.30s and 1.36 60' with a little shot of nitrous back then. Still have that car but it never gets uncovered.
