TQ cast iron intake 318 ports

He measured them and said they measured 1" x 2" so that would make it 340/360 ports. I know they used that intake on 318's also, as is, with the large ports. Maybe I'll just use one of my early manifolds, no EGR, and keep my eyes open for one of the truck manifolds like Kim said. Thanks to All!

Chrysler was funny about stuff like this, so I wouldn't be surprised to see the same casting number with both port sizes. Especially since the casting number comes up for both the 318 and 360 engines. It could be a dash thing. I found that casting number with no dashes and also with a dash 3. So there could have been some with the small port.
