anyone know where you can get GM 502 short blocks? I can find the crate engines but I'd rather get a short block....

Paceparts has them new from GM. Its listed as a 502 Partial Engine. I bought one two years ago and had it delivered to my shop for $3700.00. The GM partial engine includes the normal shortblock assembly plus oil pump, oil pan, rear seal, 502/502 roller cam, roller lifters, lifter retainer, timing set, and timing cover.

are these marine engines?

GETTINBYE

Ken,

First and foremost I am not an expert.

With the disclaimer out of the way, I will say this. General Motors will say they are not. Mercruiser will say they are not.

Question: Where does Mercruiser get their 502 short blocks, and for that matter most of their engines?

Answer: General Motors.

I have, in the past, cross referenced several mercruiser part numbers to General Motors and they are the same parts.

Now, just for fun, go to your local Mercruiser dealer and price a short block, or for that matter, any engine part, then go to your local Chevrolet dealer and price the same part. At this point you determine how much "you" want to spent for the exact same part.

You can do the same scenerio with the valve train on their high performance models that use a Crane, for the most part, valve train. Mercruiser's prices are highly inflated for the exact same part.

Not trying to #iss anyone off, just my opinion, and my money when I need parts.

I do hope that this may help you, and others, save a dollar or two in the future.

Mark,

I too am no expert. I do know that Merc. gets their blocks from GM, and their prices are higher. But, there is a difference between a street motor and a marine motor. True, you can buy the short block for the lessor price and make the necessary changes, if you know what to do. For a simple engine swap I would spend a little more money for a drop in motor rather than take apart a brand new motor and adjust the clearences. But that is me and my .02. And, I am certainly not pissed off.
