I was going to do the lid conversion on my TA but after seeing how much cutting I needed to do I traded my lid setup for the LS1 FIPK. Im happy to say it fits with no issues at all, hood has no problem closing. Im also going to cut out the area under the filter to get more cold air to it. Before everyone chimes in with the hot air intake comments that only applies to F bodys with stock flat hoods. The Ultra Z/WS6 hoods allow cold air to get to the filter so IATs are ambient. Anyways here's a pic, this is a nice alternative to the WS6 airbox if you can't find one.

 

FIPK'd engine bay. NICE!

someone stole'd your motor!

 

with that engine outta there you should have optimal airflow

JK man! Ive always wondered if this would work.

 

lol the motor is coming soon. i was surprised it worked honestly. i need to debaffle my WS6 hood to see how it fits under it
