Help me identify my motor/heads/water pump.

[snowblind]

Hi Everyone,

My water pump has decided that it wants to leak coolant out of the little hole on it's bottom/front. I'm 99% sure that I have a "long" water pump but I wanted to double check with y'all before I go buy one.

My truck is a bit of a Frankenstein. I know the heads aren't original but I don't know about everything else... I had a conversation with a mechanic friend a few months back and he figured I have "fuel injected" center bolt heads mounted on an "older" block. I figure the water pump/alt/ps probably came off the same motor as the heads but that's really just a guess.

So... What do you guys think? Are there some tell tale signs or casting numbers that I can use for identification the different parts? I'm really just looking for a way to get the right parts for the job without removing the old parts and dragging them down to the store with me.

Here are a couple of photos.
