Talk to Mike Forte at Forte Performance about a TKO application. Forte's Parts Connection - TREMEC, FACTORY FIVE COBRA PARTS, FORD RACING PARTS, FFR, MUSTANG, TRANSMISSIONS, T-56, T-5, TKO, TR-3550 Not sure the TKO can handle that HP, but then again, are you really going to be in that HP range?? 1300 is huge for a streetable application.
