Decked DZ 302
So, I am pulling out the DZ 302 from my Camaro to replace it with a 383 or 406. I have a couple people interested in buying it, but I'm not sure what they're worth. Unfortunately, the block was decked BITD when they were racing it the stamping is gone, and I've tried to pull the numbers up with acid but they must have cut too much material off.
Now, I've read that some guys are buying them even if they've been decked and stamping them with their own numbers to fake a matching numbers Z, which, obviously, I'm not a fan of but once I sell it I will have no more control of it. Anyone know a decked DZ short block will bring these days with one bad oil ring? How about if I sell the short block with the camel hump heads as well? Just not sure what's a fair price in today's market.

Is this the original block from your car? If it is then it should have the partial VIN stamped above the oil filter. That would verify it as a DZ block. If it's original to your car why would you sell it?

Exactly what I was thinking.
If the vin is at the oil filter and is legible, untampered with, and matches the vin of a 69 Z/28, and is a known real Z/28, then there really isn't much question it's a DZ engine, regardless of the block being decked. If you don't have the car and were simply told it was a DZ engine, I'd start researching the vin. It might exist. |

Block is not from my car (mine's a '68 327/4 spd originally).
I will try that route to see if anyone is missing their old 302, and that might be a win/win if I could find it.

If it has the original crank, balancer, and heads that is where the value would be. Otherwise it's not worth any more than any other 613, 386 or 010 4 bolt main block unless the vin # of a Z/28 exists.
Good luck with the vin search. That might be a big win! |

I don't know if it has any of those items to be honest.

HI the balancer is different than a 350 and the crank at the rear flange has a v cut in it

Hi , what’s the casting date on the heads & block ?

If you're pulling the engine from your car, then you'd need to at least pull the valve covers to get the date codes from the heads, and would likely pull the oil pan to check the crank rods and pistons. The crank can be determined from the rear outside flange, but once opened up the pink rods are obvious and factory pistons would also have part numbers inside the casting if they are still in there. Having seen and verified those parts, you would then know what you have and how original it is, or perhaps isn't?
Post some pics here of the rear crank flange, T/C and the front balancer. People can quickly tell you if they are correct parts. If you drop the pan, take more pics as more can be verified then too.

Thanks NorCam, appreciate the good info. I'm going to pull the engine in a couple weeks when I get back from vacation we're taking for my wife's 40th b-day.
Ban617, the block is the 3970010 casting, but the heads are 461 I think so they're not the originals.
