I have a 1969 302DZ clone. It has a partial vin 19N598017 VO104DZ stamp. I thought I was buying a real 302 until you guys picked up on the casting date number of K273. Obviously it is a re-stamp. But I'm over that. It is a 4 bolt main with casting number 3970010. It has all the right stuff, 1178 crank, 3927186 heads, 1969 winter intake and a completely rebuilt Holly 3923289 DZ List 4053 704 carb. You can see the bottom of the pistons have been drilled for balancing. I put in a new oil pump, fuel pump and line, windage tray (was missing), and timing chain. I made the decision not to pull the pistons after checking the bearing clearance was okay. It was my bad not to pull the cam to check that while I had it apart. Hey, I'm a rookie, don't beat me up please. It's almost together. Just waiting on the new valve covers that are backordered. I'm at the point now to configure the vacuum lines. Does any one have an original stock 302 DZ that you could send some pics to show the PVC and vacuum lines? I do not have smog control. Thank you all in advance for any help you can provide.
