In 69 I know that the door data plate denotes a "63C" for a mach 1. What does it say to verify authenticity for a 70
Did any 70 sportsroofs with factory smallblocks come with a c6 automatic?
Where are the partial VIN stampings located on the 351C, C6 and the 9" rearend?? I know where it is on the 351W but that doesnt help me here..
Also, if its not a numbers matching block how can I tell what year the motor is?
And finally, by using the door info. can I tell if its an M code or and H code and again how can i decipher that on the door data plate or buck tag? I forgot---sorry....
thx..
