Re: 1970 L-78 Camaro CKO block
 

That is early,but not impossible as these cars were built very late,and most likely the blocks were just sitting waiting for the cars awhile.
What's the Tonawanda build date before the CKO code on the Pad behind the Alternator?
Is the VIN# stamped there,or is it down by the Oil filter?
Do you see an external Oil cooler provision above the Oil filter Mount to indicate a 4-bolt block?

Thanks. I'm going back and I'll get pictures.

Re: 1970 L-78 Camaro CKO block
 

Good luck!

Also a couple of quick questions of mine (great input guys):

I just hopped to 2gcog to double check my info on that block stamping and am now wondering if there were 2 possible stamps for the block? Are both CKO and CJK valid for the '70 Camaro?

Also, I was going to suggest that he look for the lack of a return fuel line to the tank (Holley VS Rochester). The Rochester equipped cars had return/vapor lines going back to the tank correct?

My Current L-78 (NOT pictured, also Classic Copper) will be using above style air cleaner........

Man, I am wondering how that L-78 402 can breathe through those tiny snorkels. An open element air cleaner could free up a lot of power on these engines.

At least the LT-1 350 has larger openings to draw air from. Anyone have any performance specs or road test data from the 70 L-78 Camaro. With the low rise intake and restrictive air cleaner, I would think it would be slower than the LT-1 powered Z-28.

Looks like a super find and certainly rare being 1 of 600. I still own one of these and have owned three. Is the three piece rear spoiler original to the car?

Re: 1970 L-78 Camaro CKO block
 

Chuck, thanks for posting the info on the air cleaner. I didn't realize it was different than the Z28 air cleaner. I'll be sure to ask the current owner if he has it.

Re: 1970 L-78 Camaro CKO block
 

From my understanding the 3 peice spoiler is original to the car. Again, I have not seen the docs yet. The history as I understand it is: This car was special ordered for a customer in triple green with the spoiler. When the car arrived the person who ordered thought it was to ugly and refused delivery. The car then sat on the lot until it was sold sometime in '71.

I would do what you can to obtain it,within reason.
Don't balk or underestimate it.
