I know I'm right....
big time 1X1 1/4 as opposed to
Yes they are bigger and taller. I had old LA specific headers (pre 68) and they would not seal on a 340 port, bottom of port was exposed. Red are 64 273 and orange are 340 (probably exhaust gasket port matched)...
Ebay has the early 340 reproductions $599.

Ballin' with that new $50!
So back to 360 manifolds....
I've been thinking about this for a while.
Might be a "best kept secret".
Anyone know if 360-4 and 360-2 are different?
...and what the outlet size might be for each versus the 340.

Thanks. I remember seeing that in the MP engine manual now. I wonder if the big blocks have similar port differences? I've never seen that in print anywhere.

Maybe look at shorty headers? TTI makes some pretty nice ones.

I have a set of 340 manifolds on the 302 heads. You are going to have a clearance issue on the driver side. Due to the way the 340 manifold is designed it will hit the bottom of the head on the rear left side. You will need to do some grinding on the head to bring it down, otherwise you will have a gap and a constant exhaust leak. I used a remflex gasket to help but you still need to grind some of the head

Here's a header manifold shoot out, there's not much deference in HP between manifolds normal 360 are the best deal.
TTi shorties work well. here's a crap pic of 2 1/2" TTi head pipe off the short header
You're right. Crap pic. lol I like the subframe connectors. Especially how you added the straps on the bottom side to tie in with the cross member.
lol, all i had handy. thanks. i knew i hated welding upside down before they went in, but now i really hate it

When I was looking for these manifolds a couple of years ago, I thought that the new ones were $599, but I could be wrong. I bought one by itself, drivers side, then found a passenger side with a broken bolt hole, the front. He had the piece broken, and I had Ostrich Racing weld it on professionally. I think that I had $75 in that one, including the welding. I got lucky, and you really have to look to see where it was welded.
Sorry, I was talking about reproduction Max Wedge manifolds. Pishta started it. I was replying to post #8. Not really relevant to the OP question. Nice price on 340 manifolds. Put them up for sale if you want to sell them. They would work for the OP and you could use repro system for 340 or HP 360 dual exhaust.

Try shorty headers
The engine they test with was a crate engine so it didn’t come with manifolds, guess they didn’t have any laying around to try, but I have seen another shoot out and they about the same as 340, they figured the best combo was one of the 340”s and one of the magnum”s I forget which ones.
