I only had my 14x5.5 rims on with 215/60x14 old ET street tyres but they still work well . 12.01 @111.98 mph and 1.69 in 60 foot . Can and does run low to mid 1.6s with the 235/60x15 ET streets . Top end is not so good but I only run an edelbrock performer RPM and leave the stock ford air cleaner on ,total sleeper look . Down on mph right from go ,1/8 mile only 89 mph also .
