1972 Chevrolet c30 longhorn custom model /
Hello everyone. I'm a younger guy who just bought his first classic . I'm learning more about the truck I bought each day. I'm having a bad time figure out what it was exactly from the factory. I did the Vin decode and that all checks out. It's got a 350 with a automatic turbatic 400 and 396 gears I believe.
Any extra help would be appreciated. I'll post a few pictures. Thanks in advance IMG_4049.jpgIMG_4051.jpgIMG_4058.jpg
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
