273 and 360 interchangeability?

Well, it looks like I might finally get my hands on a 360 over here in Sweden. I have a really nice running 273 (1965) commando in my Duster today. The 360 is a rebuilt long block. Will my 273 timing chain cover and waterpump fit the 360? I'm spending pretty much all I have right now on the long block so it would be good to know what parts, if any can go from the 273 to the 360. Sorry for my ignorance, I only ever worked on this 273 :)

I have the Solid flat tapped 20-246-4 Magnum cam in the 273 today and Beehive springs. 3.73 gears out the back and a 10" 3000 stall converter and I have a 650 Street Demon Carb. Will this work on the 360? I'm getting more info on the long block tomorrow, don't know what heads are on it or cam etc. All I know is that it's been rebuilt.

I need to buy an intake since my LD4B have the wrong angle on the bolts.

I tried using the search, but could not find anything on the subject. So please educate me!

Everything from the 273 will work on the 360, except the Balancer, the trans flexplate ( you should get one balanced for a 360). One of the motor mounts is narrower and bolts differently, I think it is the passenger side. If you use 340/360 heads the ports are larger and I would use a corresponding intake. I assume you are running headers... What water pump system do you have, 69 down or 70 up?
