Edelbrock 7576 Air Gap on 318

The ld4b is a great intake for a 318. the ld4b is supposed to be cast for the 318 small ports but when i yanked mine off it had big ports. so measure the port size before buying. It's an old school intake and you can't get a new one anymore. Probably one of the best manifolds out there with 318 sized ports.

I had the big port version on the small port 318. ran really good, would have ran better if it had the small ports.
