Rock guard insert
Have a question about the installation of the rock guard insert for the '29-'30 Ford grille shell that Speedway sells.
How does that insert bolt to the shell? I don't see any holes in the shell for it. What am I missing? HELP!
Thanks, guys
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...
