71 Swinger that lost it's TA block somehow-$2500

Van Senus did not have records.
Still looking for my rebuild balance card.
But I don't recall the block number having been on the card.
If I'm selling a pig in a poke, I may have to drop price. Was someone spoofing me when they pointed out the thicker skirts and where you could drill for 4-bolts?
Were THEY even fooling themselves at the time and thought that's what it was?
I just know it's not going to be visible with the factory power steering in there..and my cramped garage.

Was someone spoofing me. NO, The block is beefier and made with more nickel then a standard 340 block, which allows you to install 4 bolt mains. Do some research on a TA340 blocks. These motors (340 destroked to 303 making 460 horse power) were made for use in AAR Cudas and Challenger TAs that ran in the 1970 Trans-Am racing circuit. The had to build 500 cars with the TA340 motor to sell to the public so they could run the destroked 340 in the TRANS-AM circuit. They are a great motor and will take a beating and with the Six Pack set they came with are fun to drive.
