Thanks for the welcome , I have a 74 TA, Vin # on title matches dash Vin. according to spec search It has a 455 motor, I bought car used , I'm 3rd owner.
However when I raise it on lift the lower block L side shows 400 modeled into block... does that mean the motor has been changed and it is really a 400,
not a 455 ?? I will get numbers that are suppose to be on front block near R - Head . If it is a 400, can I put 455 heads on it. ?
