Default throttle body and intake question

If you have a stock ported throttle body and an ls6 intake, a fast throttle body and intake, which one will make more power and how much more? im only looking to have around 400-430 horsepower when its all said and done. basically im asking is it worth it to spend the extra money on FAST parts or just go with the stock ported and ls6 intake?

thanks

The FAST 90/90 will make more power. If you are going for all out performance and every .001 rwhp point counts then FAST is what you want. You might see a 10-20 difference with the LS6...Maybe. That all depends on the rest of your setup as well. So that is not in concrete. And who really knows for sure. It is really hard to say, but with it on stock cubes and right head/cam combo you can achieve your goals off the 400+ range. You can honestly do it without the FAST too.

I believe the fast 78 & ls6 will show the same gains.
