I run 4.30's with a 30" tall tire myself in my 63 with a mild 440. It goes 3700 lbs with me in it and my best 60 is a 1.57 with my average in the low 1.60's on tracks with not so great hook. It works good for my street driving as with my 9.5 Dynamic converter it tachs about 3100 at 60 mph. I drive it on the highway all the time as I drive it the 45 miles to the track also. More gear might help your 60 but I would think suspension help should work also as you are much lighter then my 63 and should 60 ft as good or better then I do. My 63 is about 500 flywheel hp and has a best 1/8 of 7.28 @ 93.74 mph and a best 1/4 of 11.49 @ 116. And my converter flashes about 4200 and works real nice. Good luck , Ron
