I had great luck with the Summit "High Torque" mini starter which is the same size as the OEM starter of the 94/95 cars. Turned over a 11:1 brand new motor no problem.
2000 Mustang GT Steeda #0048 34k miles. 99 Cobra 4V swapped, FTBR IRS swapped, exhaust, tuned by James Gordon.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
