Speartech is outside Indianapolis,Indiana. They make custom wiring harnesses to install late model LT1, and LS motors in older vehicles. I drove that wagon a couple of years ago when it was for sale. It has a BB truck motor. Lots of torque but not as fast as I thought it would be. The wagon was at some Impala events several years ago.It had T-84's front and rear sways and the swap was pretty clean. Lots of little stuff and cosmetics that needed to be finished but a good starting place if you wanted a BB wagon.
