1966 Barracuda "car ****"

On engine parts, the after market 318/340 4340 Scat cranks in 3.31" stroke are a direct replacement for the 273 crank. It looks like Egge's website has forgotten about the 273, they used to make Commando pistons. But there are plenty of manufacturers that will tool up sets of custom forgings for $1K or less.

JTT http://www.forabodiesonly.com/mopar/member.php?u=28986 in Finland is just wrapping up a build on a hot 273 for his Vintage Road Racing '66 Dodge Dart and may have some European parts source advice.
