Quarter Mile Gear Selection
If I were the OP I'd go with 4.10's. When my dart had the 340 (apples to oranges I know) I went from a 3.91 to a 4.30 it only picked up .007 and that was in 60'.
I like 1/8 mile racing but would like to run my car in the 1/4 again, in good air this time. It ran 10.008 At 134.74 in less than ideal conditions, I'd like to get a 9 second time slip with it. Not many naturally aspirated 9 second street/strip cars around here, even less with small blocks.
