Maybe the person that said that, meant it will work on a 360. 40 prefix tells you that is a very late 70's part number at the earliest, so if you are thinking it's a 340 manifold because of the last 3 digits don't , that's only on engine blocks ...

Anyone out there have more info on it? Thanks! Do you have a set of intake gaskets ? If so throw one on there , 318 ports will be smaller than 360 ports otherwise measure the ports and post it up , someone should be able to tell you what it is . Is it a 2bbl manifold or 4bbl ?

If there were they are extremely rare. What you have is a 360 intake even if it came on a 318. It's really heavy, has EGR provisions and is a very good intake for performance, better for example than an Edelbrock Performer. I'm using one like it on my 86 318 because I got it for $15. It's a spreadbore so I may end up using an adapter to use my 600 Holley. Mileage is a factor so a Q-jet or T-quad are also possibilities. All in all, not a bad intake. R.
