Have you gotten the PHS or checked the date codes and numbers on the motor? Either way, I'd still proceed with the swap, but I agree, I would hang onto it if you have a place to store it. (even engine stands are only like $40. Nice way to store it)

You are right Augy, it's basically a direct replacement (400 for a 326) especially if you are swapping over the pulleys and brackets. Then only real issue will be setting up your throttle rod linkage for the (I assume) 4V carb/Manifold in the 400 motor? But that is just a matter of adjusting the length, and it will be pretty much the same...

But yes, it's very straight forward! Just take your time, soak down any bolts that you think will give you trouble such as exhaust manifold bolts etc. a day or two in advance, and you should be set!

Good luck!
