What's my restriction?
 

Which is my biggest intake restriction if I'm installing my new
TR 220/220 .553/.553 112LS cam package? :confused:

1. MAF
2. Throttle body (It's a 1999 car)
3. The intake manifold itself?

I have a limited amount of funds and I need to ditch the most restrictive part first. I would think the Z06 would be feasible, since it has to be removed, anyway for the cam installation. However, I've heard the throttle body on the 1999 F-body's is the smallest of any year model. Which of the above will give me the best airflow for the dyno tune with my new cam?

neither of the listed items are a huge restriction, but out of them i'd get the ls6 intake. and you dont have to remove the intake for a cam swap. and also all ls1 TB's are the same size, the only thing that changed is the TB cam gears and the 98-99' have the smaller one which is better.

id say get the LS6 and port your own TB! leave the MAF alone.
