Porting a FAST Is it really worth the extra $$$$ to port the FAST intake or should I save my money. I have some 1.5 TEA 5.3 heads that are milled to 58cc. I will be running N/A with no Power Adder at all.
What do you thinK?
Should I port THE FAST or just bolt it up?

If you want it ported just do it yourself. There are witness marks in it so you dont go too far, plus it is 3 pieces which makes it easy to get to all the ridges that you want to knock off anyway.
Personally, I would not pay the kind of $$ that people pay to have these ported. I would either port it myself or install it unported. No offense to the FAST porters out there, thast just my personal preference.

Thank You for your honesty on this. This is what I was thinking myself as well.

$250 is not too bad to have it ported though.

There's a whole discussion going on about this topic.
https://ls1tech.com/forums/advanced-engineering-tech/581507-fast-90-intake-porting.html
the problem is the people who know how to port the intake properly, beyond a port match aren't saying anything because they're the ones making money off it. Until some of us DIY people take a shot at doing it ourselves and have the resources to do back to back dyno testing it'll be hard to get definitive results.
