Eric built it for a heavy duty street trans goôd for low 10s, I don't remember all the specifics on the rebuild cause I trusted his integrity on the build and at the time he was building jack cottons transmissions if I remember right- ran good from the day he installed it. I paid alittle over $2000. For it. I recently changed the stall converter from 2800 to 3500 but haven't driven it much since, I'm getting all the bushings replaced, new floorpans and the frame notched.the car has a Denny's driveshaft and a 9" ford rear.
