The 305, 351, 401, 478, & 702 V6 & V12 motors are all 60 deg V6's. Great power for towing and pulling, but heavy and get 10 MPG no matter what you do.

Also look up the 6066 GMC email list on yahoo (linked from the above page too).
If you decide to upgrade that '62 305 to a 351 let me know. I'm parting out a '66 GMC project.
