My friend has a 70 Road Runner, 383, 4 speed, 4 barrel.

He wants to find the proper carb for this engine and I told him I'd ask the experts. He has a build sheet (mostly legible) if needed. He's also wondering if there was some sort of spacer or a certain gasket used for the carb. He says it has some sort of metal gasket at the moment.

So... anyone?

Thanks...
