Edelbrock Torker II 340 on a 1966 273 v8??

Apparently there is a pin that does not allow the manifold to fit perfectly on the engine. it is a 66 273, the carburetor is a 4-barrel Edelbrock.

you can pull that pin out.
273 ports are like 318 ports, I wouldn't worry about the port size.
What I would worry about is this intakes designed purpose vs your engine. If your engine is stock, or remotely close to stock, I wouldn't recommend that intake.
