Edelbrock Torker II 340 on a 1966 273 v8??
- 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.
Engine is stock, been working well with the 2bl holley, trans is 4 speed.
