Engine Swap? Engine Drop!

Whats up everybody.
I was just sitting here thinking, dreaming even, of that project truck I was thinking of buying. Its a 46 Dodge Pickup. It has no engine or tranny, but the body is solid. From the pictures it looks like it has no rust, but I'll see when I go see it.
I was looking for information on the original trucks and I haven't found much. I have no clue what the original engine size would have been. There are a few restored 46 Dodge pickups floating around that have 350 Chevy small blocks.
I have never put an engine in a vehicle, nor have a taken one out. But I know from experience that Motor mounts break. Logic tells me that Engines must be held in, they do not just float! How enlightening.:rolleyes: My question is this: Are all engines universal? Other than having to make room for a bigger engine (make room for manifolds,etc.) can any engine be placed in any body?
I wouldn't mind having a 350 S/B but I would like to know if I have more options just incase..
Thanks for the help the other day with my questions,
I think I am going to get a Miller MIG Welder, and I found a Stage 2 Air Compressor with an 80 Gallon Tank, I think It was 15.1/13.7 SCFM. Thinks almost 900 bucks though... :( Guess thats not bad.

I was just thinking, Its a Dodge... and even though its a 46, would it be ethically sound to put a Hemi in it? I know the Hemi wasn't released until 48.. How bout a 426 Hemi? 7 liters of displacement? :D (its like cramming a V12 in a Mini-cooper)

Jeff,
First get the truck - then you can measure the space that you have to work with and you can put whatever will fit that size in it.
Good Luck

Motor mounts are not "universally" placed, but are relatively easy to fabricate. You CAN put just about anything in anything, just a matter of how nuts you are. For example;

A hemi... why not... a 426 hemi... sure... but let me ask you this. Have you priced a hemi engine? You may be a little sticker shocked! Like in and around the tune of $12,000.:HMMM:
