The bolt holes are in the same location just angled differently. You can swedge out the holes to the angle you need. You may need to make angled bushings to locate and support the bolts. no biggie. People do this currently to fit an LA intake on Magnum style heads. That intake will work better on 318 heads- it was originally designed for a hot 273 then 318 application.

I advise against trying to bring port size out to 340/360 size. Here is a 360 gasket on my 273 Offy dual quad. If you bring it out to the 360 size you will have near paper thin metal afterward. My suggestion is to run it as is with 2 Eddie/AFB 500s, or go with a single carb set up. Other manufacturers may have left enough meat to grind away but it looks like Offy intended this manifold for the 273.

Gasket beyond mating surface. The port is just below what gasket you can see.

i would leave the ports alone...on the motor it is designed for it will offer the right tuning.
seeing as the intake was designed for a smaller bore 273 IMO it wouldn't make sense to molest a nice intake to fit a 318/340/360.
if anything see if you can get the 273 heads to fit the 318 and then you can run the intake.

It may be cheaper to hang the manifold on the shop wall than to build a car around a bargain manifold.
Thats probably great advise. I was just wondering if I could get away with one!!!! It looks cool and it will look good in the shop. Now, here is another thing. I have a 67 Dart that I am buying back from a buddy who wants to sell it. I sold it to him for next to nothing a few years back.
How much beef, would one need to build into a 273 to use this and is it worth it?
If I picked this 67 back up, I was thinking cheapo commuter.

A friend of mine recently built a 273 and used an NOS one of those intakes on it. He used around a .450 lift solid cam in it from memory...along with a couple 500 cfm Carters.. It's just a cruiser engine going into a Ute (he has about a half dozen small block dual quads saved up  think one is going to go onto a 340 he has eventually too...just for looks more then performance really)

I bought this today from a buddy. Its a 273 manifold that I really dont need. However it will make a nice shop decoration if nothing else. But I was considering building a 318 or 360 for the 38 Plymouth business coupe and thought it may give it a nice look.
I dont want to spend the $$$ to build a 273 for it as 360s here are very cheap.
I know some of these can be used on 318s, ect but also know or heard that the early ones can not. I dont have a 318/ 360 here at this time to check it on.
Any ideas. The part # is 5488 and its an Offey???
here is a pic or two.

Why not a 273. Really not much to build one unless you want to spend the $$ on forged pistons. You can get a good street CR out of the 2bl motor with a little machine work. As far as the manifold that's what is on my motor that I posted pics here.

John, nice looking motor. What kind of HP will it put out? And you used the stock pistons and rebuild kit???
I know nothing of 273s.
