The 3970010 was pretty much the standard 350 casting used for many engine options. So, it's 44 years old and only been bored .030 over once? Sounds fishy. You need to research this a lot more.

I think if I buy this it will be a learning experience as far as removing tranny and parts then lifting engine out if it blows up then I still have my original plus he's got headers carb intake for 1000 bucks it might be worth the buy and just to learn Originaly I was going to just get a shop to clean up and refresh my original heads shoot that's 1500 bucks right there

Rebuilding heads is not $1,500.00.

This motor might be worth it if it is fresh and never been run. But, you'll want documentation of the build. The cam came with a spec card. Get it. Does he have receipts for the parts that went into it? Does he have receipts from the shop that hot-tanked, magnafluxed, and prepped the block?

Whenever you buy a motor from a "mechanic" you run the risk that he did not know how to use a torque wrench properly, or didn't bother building it to correct specs, or did who-knows-what. But, you might get a good deal.

$1,500 is not that much for a used motor if it is complete from carb to pan, which this doesn't sound like it is. I would want documentation before dropping $1,500 on a "so he says" motor.

When you hold it up against this, for 1600 bucks, free shipping, it doesn't seem like such a good deal, does it?

Ah, I see. Your situation is a little different than it would be if you lived down here. How may horses do you think your 1500 dollar engine is going to put out? And, is that 1500 Canadian dollars? And, is the exchange rate different enough to make an appreciable difference?

See if you can get him to run a compression test on it, shouldn't take too long, if you get numbers of more than 175 or so, you'll have a pretty peppy little engine there.

I noticed the ad for the motor did list an Edelbrock carb. Assuming it has an electric choke and is basically new, this could be a downright superb deal. It sounds like it has a 4 bolt main and possibly the factory forged crank (which is what I'm guessing the "steel crank" bit is).

What is unknown are the heads: He will probably know the casting number. Get it. I doubt it comes with the original heads, but you might get lucky. Also find out what work was done to those heads. Ported, polished, valve job? Valve sizes? That's where a lot of your power is going to come from--possibly more so than the cam. Based on all the Edelbrock parts, "mild Performer" cam might well mean the Edelbrock Performer Plus, which is indeed a mild cam--204/214 @ .050. If any porting was done to the heads, it might be worth looking into a more aggressive cam...
