5.2L-5.9L FASTMAN TB's:
For the 5.2L I recommend my 1.980 bore "50mm" TB.
For the 5.9L I recommend my 2.030 bore "52mm" TB.
If towing is your main concern I recommend the 50mm for the 5.9L

The 2.030 bore 5.9L TB was designed as a performance TB to give the best combination of low end and top end performance for street/strip use and my most popular.

SPECIAL BUILD TB's:
53mm - This TB is for the more serious builds. Usually someone running ported heads and cam and generally running higher RPM racing use.
