is there a difference between the 67 340 and later 340s? Other than the cam differences between manual and auto cars in 68. Is the 67 casting different? Better?.
Casing is dated late 67 for a 68 car I am sure. But supposedly the 67 castings are more desirable. Trying to find out why or is it a myth?The 1968 model year was the first year for the 340.
The '68 model year started during the 1967 calendar year though, so your block may have come in a '68.
AFAIK mechanically,the 68 to 70/71 model year 340s were all same short blocks (exc the one year only manual-trans cams, as you noted), and all had 2.02intake valve heads. Covers and such changed in 70, and intakes/carbs in 71. The 2.02s were dropped to 1.88 I think 72, Compression was dropped I think in 73 and those low-C engines had different guts.
Slow-typer again,lol.
I've heard the main webs are thicker on the 67 castings. If you have anything of value to add I'd like to hear it. If not kindly don't respond..More desirable for what. lol
I got one here I'll let you have for $17,000. lol. I desire your hard earned cash. I might have a second one, but that one will be worth more on account of if you buy the first, it is suddenly worth infinitely more, as it might be the last available one on the face of the Earth..
Ohhhhhh, chit! I just checked, and it's dated Feb-68, so sorry, lol; there go my dreams.
you forgot the 70 aar and T/A blocks have filled oil pan rails, maybe more that I don't know about.AFAIK mechanically,the 68 to 70/71 model year 340s were all same short blocks (exc the one year only manual-trans cams, as you noted), and all had 2.02intake valve heads.

that exactly what this block is.. 6/28/67I have had several June 67 340 blocks, nothing different in any 340 blocks ever...
A 340 block is a 340 block...
It's what you put into it and on it that makes the difference....
I have this info saved on the 70 340 TA blocks. Ignore the circled paragraph & read the info next to the blue arrow....

Outside of the blocks. A vertical stiffening boss cast up the sides. 70 and up, both sides of block around freeze plugs.I have had several June 67 340 blocks, nothing different in any 340 blocks ever...
if you have an original aar or T/A body missing it's special oem block, they are probably pretty valuable. Even if it's not "numbers matching", it's probably valuable to complete the package.Are T/A block worth that much tho??? Just got this T/A 340 motor that was built and sitting for YEARSSSSS and it was never run and still has Assembly lube in her. Was .040 over but the block is in Perfect shape. Completely Forged
