14.45 with 12 sec combo... HELP

I think you need another convertor. I was running a 360 crate motor (stock short block 9-1 comp, stock magnum heads and a .501/.513 lift cam,M-1 intake and had a 9.5 convertor. It ran a best of 7.45,90mph I changed to a 8 in 5500 convertor and ran 7.27, 95mph, 1/8 mile. According to Wallace Racing calculator that would be 11.71 and a 11.44 in the 1/4.
