Can anyone give me info on these?

I need a cast 318 intake which has nothing to do with your delima!! I have heard that intake will fit in a large flat rate box, but there are 2 different size boxes, on will fit I am told. If you decide to ship let me know the details. I would prefer the square bore intake myself but can use either.
I admit it is not a $100 piece to me. Not to mention shipping.
IIRC, If you really need a cast 318 intake, the ports on both of those are going to be big for a 318 head. Some of the 318 guys would know better than I .
