TM5 versus Torker and 340 Torker
Or an early version of it, most Excellerators I have seen had straight runners going to an angle at the port window of much like a TM-5, this one had runners that swept out from the front and rear plenum walls similar to Torker II 340/360 but was about 5-1/2 inches deep from the carb pad to the plenum floor.
