It's impossible to visually verify the type of rods by just looking at the end caps. Tell your buddy that if he's serious about buying this short block, he should at least disassemble it to verify the condition of the rod and main bearings. In the process, he can verify the type of rods being used.

He'll have to pay for it, of course, but a reputable seller should be willing to go along with that arrangement.

Really every aftermaked rod picture online has bottom part rounded...only stock one has square is thing on the bottom part... So disassemlby is the only way to verify?
The reason to get shortblock for him its fully assembled and dyno sheet show what power it made before he decided to part it out
Can you put camera scope and see markings on pistons? They should have reliev marks stock are all flat?

Wisnia, I don’t know anything about connecting rods and such, but it seems like you have a good train of thought here. Why don’t you google “forged rods for 350Z” and then hit the image tab to compare the end caps to the ones in the photo. Also google OEM 350Z rods to see it they are exactly like the ones pictured in your post.

Is not a ‘short block’ an engine without cylinder heads? If so, you shouldn’t need a camera scope to see the tops of the pistons, you should also be able to examine the condition of the cylinder bores.

Unfortunately the Z has become the car of punks, hoodlums and outright thieves. So a lot caution must be used in buying any used parts or components. I wonder if the Aston Martin people have this problem. After all, Aston’s long time slogan has been “Built by gentlemen for gentlemen” I wonder if they will even sell to women, or punks, or hoodlums.

There's only so much you can guess from online pics. But having inspected and installed high-end rods from Carillo in Nissan race motors, there's no SURE way to tell, short of disassembly. My GUESS is that this build used stock rods that were worked with ARP rod bolts, but that all it is...a guess.

However, if the only reason preventing you from doing a disassembly and thorough inspection b/c you're trying to save money than just say you're willing to gamble on this purchase. And do a little more research on the VQ35DE pistons- they are not just flat tops.

Its not me, its my friend
He is going fi and he is thinking of purchasing whole long block from a guy localy... Do you think private person would disassemble it for peoole to examine?.....then it kills the whole purpose of buying assembled engine
ill advice him againsst buying it once again
Just find it weird there is nothing to confirm my findings

Why doesn't your friend ask to see the invoice from the build?
