porting factory intake this may be a dumb question, but can you port the factory plastic intake manifolds?? i know you can port aluminum intake manifolds but wasnt sure if you could do the same porting on a plastic intake? If so same spots as normal or just the TB location?
just curious because me being out of work and not having money to finish my build, i am thinking of porting my heads, throttle body, and intake. instead of buying new stuff, at this time. it will help me get a little more power, and i may have enough money to finish the little things to the car moving!!..
thank you.

Very hard material to work with its a pita and like the others have said it isn't worth your time. I don't recommend doing a butcher job on your heads if you have no experience in porting things, the throttle body will be more forgiving.

wont be my first rodeo porting aluminum heads.. ive port matched several sets of heads, 1 throttle body, and many turbo inlets, flanges etc. i am pretty good with metal work. i used to work at a racing fabrication shop before. I don't know to much about engines and combos but when it comes to hacking, machining, tacking, and fabrication of parts im not to bad.
i am going to start them, and then bring them down to my old boss to have him finish them!! he will also do the valve job.
thanks for your info guys, i will not waste time with the intake.

my opinion is its not worth it. and here is why, if you have an ls1 intake or a truck intake, just upgrade to an ls6 intake.
the thing with the ls6 intake is that it is already a pretty good design, and the people who have ported the ls6 haven't really gained anything.

Trending Topics
Think about it this way:
The ls6 design is so good that it takes a clean slate intake with a larger plenum volume and tons of R&D in runner design for a Fast intake to gain on average 10-15hp over it and after being out since ~2000 Fast and MSD are the only 2 companies who have been able to effectively design a decent improvement.
Some dremel work just simply isn't going to help you and honestly it's more likely you mess up the runners than improve anything.

its going to be mainly stock at first, i just figured id port the heads and throttle body now so its a little better then stock.. ill have headers, an exhaust, and a built rear.
then over the winter i plan to get a cam, springs, lifters, with an intake, bigger throttle body, injectors and nitrous.. that's going to be step 2. then better heads, and finally the 408 bottom end. id like to get the Holley efi.. one day i may go turbo and i have a few friends with the Holley and it is great for tuning and safe nitrous tunes, among many others.

It's is DEFINETELY worth it vs spending $1000 on a FAST.
I had LME dyno a ported truck i take vs. stock FAST 102 and it beat the FAST by 17hp/15tq at peak. More under the curve..,.
So yes,it's definetly worth it.

TBSS/NNBS style.
Corey Harris ported it but he's out of the game. To many folks complaining about pinhole leaks and wanting him to eat $100 on shipping for an easy 5 min fix they could do themselves. Kind of crazy when the port job only cost $300 shipped...
Bob@Peak Speed offers the service for around $500 plus shipping and has learned a lot from Corey so he should be able to take care of you...
