Is this a good deal? Will it do what I want? Carb/Intake

Looking for an economy solution, both price and fuel, for my 1972 Dart 318.

Currently I have a 2 barrel setup. The 72 Carter is I think 375 CFM with 1.25" primary bore.

I found this intake on ebay and was wondering if it would be a decent choice. Also wondering what my carb options would be. Does the spread bore intake limit my carb choices to spread bore carbs? I was originally thinking about an Edelbrock 1406 performer and found one locally on CL.

What do you think this would do to highway fuel economy? I'm currently averaging 15-16 mpg driving 55-70 MPH. Averaged over the last 500 highway miles. I know I will get worse in town as I will be tempted to get on it some but not much as I want this 108k mile 7.25" rear end last for awhile.

Also wondering if this intake will necessitate modifications to my stock coil mount.

I'm just thinking for under $350 this would be a good deal.

Thanks in advance for your expertise.
