not raining on my parade. it wasn't my idea that it was a 302. others suggested it on this sight and others. Yes I agree many hotrod builders are using the LS engines today and they are in the limelight because its the latest and greatest. However, there are many more restorers and clone builders out there in this industry! If this was a rare engine I would rather sit on it till I could find the owner of the original vehicle. It is however, date specific as casted and can only have been installed in a 1968 or 1969 Chevrolet vehicle originally,which would not necessarily be a Camaro of any kind much less a Z/28 . Don't mind sitting on it a while longer if theres a chance it may go back under the hood it came out of! I have no use for it myself anyway except as trade/cash value to put towards locating and purchasing a set of 1971 Ford 429SCJ heads to go with the 71 429SCJ block, crank, and rods I'm also sitting on and will be using!
These are the numbers I get from Mortec
3970010 69 302 Z-28 2 bolt mains
3970010 69 327 2 bolt mains
3970010 69-80 350 2 or 4 bolt mains
I have a 3970010 block in my 76 Corvette
Chevy Small Block V8 Casting Numbers - Mortec
Let's assume that the suffix is NOT TBD....let's try BD
There are two uses in 1968 for BD, both 307 motors, one in
chevelle and one in nova, both 4 speed 2bbl motors
Motec site is noted for being really incomplete data....it's a good start but doesn't tell all.
block casting number? 010 blocks are what you list..... block casting is the casting number while the suffix code tells what the block was machined to be and what the engine config was. I think 010 blocks were the most common casting from 69 up thru
79 or 80....at least in my experience. Just because the block was an 010 casting doesn't make it a Z/28 block... the DZ suffix does. These are the books I use:Attachment 69457
OK, you're the winner. This is why the site is losing members fast.
It's not a contest and there are no winners except for the person who receives the RIGHT information and not some convoluted BS.
In the OP first post he states he has an 010 block. All the information I have indicates that that was a widely used block but NOT for a Z-28 irregardless of any other markings, stampings or whatever on the block. If you have in formation that contradicts that, post it.
IMHO, we look like fools if we post erroneous information and if you can't see that then you're part of the problem and not part of the solution.
