If you get an older TR with medium-sized runners, and use two smaller carbs set up for the operation it should be great. The long runners actually build torque at lower engine speeds, there have been published dyno tests proving that the torque is bietter than a regular intake below the torque peak, I think the last one was Car Craft about 3 years ago. But you cannot take the latest TR built for a 600-inch engine and expect the same results. The carbs have to be dialed in, too. The single four-barrel tops have lousy mixture distribution so forget them.

30 years ago I saw a TR on a road race car that had been converted to electronic fuel injection. Ran strong, looked BAD.
