For the price of a good set of 4V cams, cam gears, new chains, maybe tensionsers, 32 springs etc... you could just do an Eaton swap off of a Terminator.
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 ****.
