Different cars, different throttlebodies, different engine management, different throttlebody heat arrangements.

The pre-2000 Northstar throttlebodies are coolant flow heated to prevent bore and idle air passage icing. Deleting that slight amount of heat accomplishes exactly nothing. If you think it does, please post the before and after dyno sheets.

Not bad for a thread that is 8.5 years dead...............
