Default 478 Toro flow

I have a WTB ad on C/L for V6 engines and I got a reply from someone saying they have a complete 478 toro flow. Though I'd prefer a gasser I am still thinking of looking at it. I was thinking of offer no more than $300 as this is the diesel and parts a scarce. Sound good?

Questions:
Anything in particular to look for since parts are ultra rare and hard to get for these?
Certain issues in certain years to look into?
Do the toro flows also have the engine number stamped on the passenger front side of the block?
What would it take to convert it to a gas? Possible?

$300 sounds good to me if it runs O.K.. Parts are gone, but sometimes they show up on Ebay. I have seen gaskets, valves, injector pumps from time to time. A Toro-Flow can't be converted to gasoline, way too many differences.

A 1968-up Toro-Flow II is preferable, they were painted green and have oil coolers. Most important things I would think to look for would be low oil pressure and bearing knocks. Not sure about engine numbers.

Thanks for the suggestions! Found out he is 3.5 hours from me so going just to See it won't really be possible like I had hoped. Relying on pictures.

Hey guys, here is a picture. Looks pretty rough to me. Looking at the water neck I can see rust, telling me that engine has been sitting Out for years. That leads me to think it had issues at one time. What do you all think? Due to it being a diesel I think I may pass on it. Would be Awesome to rock a toro flow in the GMC, but this one I think will be a hassle.

I agree. A little too rusty. It would be good for some parts, but I would pass on it for a rebuilder.

Thanks, If he were closer I'd go look at it, but the main turn off is that he is 3 hours away and will probably want an arm and leg for it because it's such a "rare" engine.

Yes, definitely agree. There is way too much rust. It looks to be pitted real bad. I would pass unless it was free!

I was gonna offer $50 for it, but when he told me he wanted to trade That engine for a Toyota land cruiser engine I figured out that he's another one of those people that thinks rust is worth its weight in gold. So I didn't even bother responding anymore.

Thanks for the offer! I'm in Oregon so a couple states away. If I wasn't restoring another truck I'd totally be up for a road trip. Hope someone is able to pick up the 478.
