Every TNT 440 engine from the '60's that I have ever seen have unique exhaust manifolds that curve up to the level of the edge of the valve cover. Minus those, I would suspect you have a standard 440 whose performance enhancements are strictly cosmetic. Although there was a high performance 440 in 1966, it was not offered on Imperials. The TNT designation did not begin until 1967, and was a package of performance equipment, including the 375hp engine. An examination of the your engine code stamped on the block would tell the tale for sure.
