Opinion's on DZ blocks
 

Just trying to verify the 2 blocks

Both appear to be authentic to me. Top one may have been V0306DZ originally.

Would be nice to do a search for the cars these blocks were born with.

Paul

My 0307 is similar

Both appear legit... the N543xxx vin didn't come out of NC did it? There is a Dusk blue dk blue car sold out of ATL now in Ohio which is a mid nov car which I traced the engine back to NC - in that VIN range.

Thanks, gentlemen for your input. I am doing a search for the one with the VIN now, I will update any new info.

Bill, Just curious what is the casting dated on your block, you can PM if you want.

What was someone thinking ? the 86 day of March? Too bad, don’t think it’s a Flint mistake, someone added the 8

Jeff my sample V0306DZ has a casting date of B 9 9

I just got off the phone with the current owner of the Z/28 for this engine, he switched the car over to an LS conversion & has no interest in the original engine & has no interest in selling the car. End of story.

That 0386 block is not the only one out there with an "8" where a "0" should be.

I would bet the 8 was there first and someone tried to correct it.
