Hello there! I am new! My name is Cristian and I am from Orange County, CA!
I bought my 71 nova about 5 years. When I bought it, the seller told me the motor was a Pontiac 400 small block out of a GTO. I knew very little about muscle cars back then and I thought I was buying it for a good deal.
Now im 23 years old and wanting to rebuild the motor yet IDK what I exactly have. I was looking around the block and I saw on the passenger block above headers had some numbers. I also looked under the distributor cap. After doing my research I understood that the 6x heads were never in a GTO to begin with because they started in 77-79. I uploaded two images. Where else should I look on the motor?
The numbers by the passenger side above headers were C306 Then over the last spark plug it was D then N. Also vertically as you can see it is GM3 and horizontally 6X.
Under the distributor cap as you can tell by the picture the numbers are A038.
I googled these numbers and have no luck. Can anyone steer me in the right direction on finding out what I exactly have? Thank you. I really want to build this motor to 300 ponies or more!
