Hey guys I'm sure there's been a lot of posts written about numbers matching for engines and trannys. How can I tell if mine has been changed out and what I have? I have 69 C20 that was originally a cab/chassis model and I'm pretty sure the motor has been swapped out but I can't be sure. What should I look for?
