389 vs 400
I'm a brand new to this site and am thinking about purchasing a GTO convertible. I'm partial to the '66, 67' 68' and 69's. I've got some real basic questions that I would like to through out there. Thanks in advance for your help.
I understand that the 400 first became available in '67.
Was 66' the end of the 389?
What is the difference in these motors?
Are they both big blocks?
I think that the Chevy 400 was a small block and I have heard that it had some overheating issues in hot climates. I live in FL. Also, someone once told me that the cooling water did completely not surround the cylinders on the Chevy 400 which may have been the reason for this. Is the Pontiac 400 similiar?
Oh yeah, when did the 455 become available?
Is there a good book where I could find basic classic GTO information?
