I have an 03 qc 2500 with a 5.7. I have been looking at a 6.4 to replace my tired old 5.7, she has 193,000 on her. Talkin to another fella he had made mention of the V10. Are the mounting brackets the same for the motor and tranny? Will the bigger radiator mount right in. If any one has good info for me please let me know. I am gona make a change but want only to spend about 16,000, motor, trans and rearend.
