Think that happened to me in reverse - bought a 273/235 from a 66 Formula S 4 speed Barracuda on ebay for a measley $150.00 - only 2 bidders. Had to drive like 200 miles to pick it up but that was no big deal. Other than the Commando valve covers and chrome air cleaner, it was a complete motor. After hot tanking the bore only needed a hone so the original high compression pistons could be used. The rods and mains were all standard so everything worked out great money-wise. It will be a perfect replacement for the 273-2 in my 65 Barracuda.
