ZL1 engine

[SuperNovaSS]

I just picked up a ZL1 engine. I was wondering where I could fine date codes on the block. There are no dates on the side or rear of block. Also if anyone has any advice on special instructions I should give the machine shop when I take it over there I would appreciate and input. I have attached a picture if anyone is curious.


Thanks,

Jason

Be very sure to take it to a good old hot rod machine shop. if you have to have it bored out be sure that they use a fixture that is indexed off the crank centerline so that the bore is 90 deg to the crank. Same for if you have to put a sleve into it. Email me a price if you want to sell it. I would love to have it.

Since my White '70 BM Phase III came with alum heads on a LS-7 why not give it a Alum block to go along with it. Would that not make it steer easier??? Of course I would have to put a 454 crank in it to make it a larger cube like a '70 vette should have in it. Then again I could just build a very real looking clone out of that old '69 X-44 camaro I have setting out back.

Just heard back from the machine shop. No cracks or flaws in the block. So it should be for sale soon. It will need new sleeves to make it a 427 again. It now has sleeves that make is a 510. He's checking the heads now. I'd rather sell it to someone here than put it on Ebay, but still have no real idea of value.

Maybe a better question was "what do you want for it". Good score.
Now I guess you have checked over the sides of the casing and there is no sign of a casting date.
What about the winters snowflake, any sign of SYC, stamped there??
Turn the block over, upside down, does it have any stamped numbers in the machined surface, these may only be a small numeric number not the alpha numeric codes you normally think of. If you got the caps, did they have any numbers stamped in them.
Finally clean the block on the inside, and get a good flashlight, and someone with vision a lot better than mine, and look for anything else stamped in the block.
Porterfield told me the same and it was amazing what turned up.

Finally after getting "acquainted with your new toy, how hard is it going to be to give it up ?????

I think there were some numbers stamped on the oilpan flange. The parts are at the machine shop now getting checked for cracks. I wanted to have this checked before I sold it. It does have the winters snowflake on the front. As far as asking price is concerned I'm not really sure of the value, any input would be appreciated. I want to be fair.
