Throttle Body

have a L67 3.8, with a turbo, stock TB is 69mm, the bigger TB are 72mm (ported stock TB), 75mm (stock Northstar TB), and 77mm (Ported Northstar TB). So will 3mm, 6mm, 8mm bigger really make a difference to cover the cost and time of the upgrade.

Dang I brought that hood thing up to a buddy of mine a few months ago. Guess I know what it will look like now.
