What Modification Do You Regret?

Kind of bittersweet story.70 El Camino,396/th400/4.11 out rear.Bought a old Tci bracket converter(10 inch).Ended up stalling five k plus.Put square ports on it,made it worse.Put a two circuit 1050 dominator on it ,actually sweet anywhere to drive.One sat nite,in 2003,went to run the solids.Next to last( 2 exh.)Lash was .300+.I make a phone call,and trade for a real car.Hell, at least my story has a happy ending.
