Thread: New to L67 motor, need quick questions answered

cant just go droping pullies on a termi either with out a tune also.


but yea its alot more than just changing a pulley.


im on the stock pulley and run faster than alot of guys with a 3.4 pulley. why? because im not knocking as bad and can use my boost effectivly.

its not all about boost.

For the GP...get in th General Tech Section and read the Safely Modding Your 3800 Thread I wrote...should help you out pretty well since you aren't too familiar with this platform.

Yes...you can...very much so...a lot of Cobra guys run down from the stocker to a 2.85" or 2.76" as a FIRST mod. Like Mini said...they are I/C'ed from the factory so they are a little conservative. And with headers and a intake/ported TB/plenum you can go even lower. Tunes do wake them up a lot but you can drop a pulley without a tune and not have to worry about anything.
