I have 1979 Ford with a 400 C6, the tranny is weak, a friend has C6 off of his race car with a 390....will this bolt up? Or what engine combo do I have look for to find a matching bolt pattern?
Any C6 from 351m\400\429\460 will interchange with each other.....352 , 360 , 390 , 406 , has a different bolt pattern and will not boltup to a 400 .......fd
