Dana Camaro block number question

[Rixls6]

COPO,
Wouldn't the iron sq. port heads be #391?
I'd like to hear more about the over the counter Berger L88.

I also just scored a `67 L88, but with Aluminum #392 heads. The block is a 3904351 4-bolt.
It has a stamped code on the block of "IT". Does the one you found have a code stamped into it?

"What sort of casting number should be on an engine block in a '67 Dana 427 Camaro? Any way a 3855961 would have been used? Most sources say this was a '66 396 block but I saw one mention as a possible 427 application.".......................Id say either a 351 or a 321 would have been used depending on when it was made.June 67 had 321 blocks and 351s were used around May 31 and prior..as far as 961 castings being used as 427s,it didnt happen regardless of what the ncrs guidelines say are "possible". I have the motor from serial #000004 427 and its a #942, and dated Aug 12 65..That tells me the 942s were cast before the production run of the 66 began, so i cant see GM boring leftover 396 #961s out to 427 cu in ..It does give some ebay sellers a reason to sell a 200.00 block for 5000.00 though.

Tonawanda engine plant assembled 277 of the 427-430 hp "IT" for 1967 (L-88). What info is stamped on the pad and the casting date and casting part number?

I have a few OTC IT L88s where the build date is down on the starter flange. Hi Drew !
