Aftermarket Intake Manifolds
Looking for people on here who actually have swapped out their factory intake manifolds for some sort of aftermarket offering. I've read a lot of posts regarding pros/cons, but mostly from people who got the information second hand.
Since the truck intake is too tall to fit, I started looking at LS intakes, but I was quite surprised to see them going for $180 - $300 (if anyone has one they'd like to sell for a lot less let me know). So being at that price point, I figured maybe for a bit more monies, it may be worthwhile to simply go aftermarket.
Who has done some before/after testing with different intake manifolds? Ideally something that's similar size to LS intake manifolds, since that's what I can fit.

From what I read, seems like the dorman intakes are not made properly to handle any real boost pressure and ends up cracking.

Didn't think about that. I have stock 799 heads. I'll be running a DBW tb, I am not sure if they are 3 or 4 bolt for those. If I could run my truck TB on the LS intake manifold that would be ideal. If not, I have a NW 102mm TB that I was going to originally use for an NA build on it as well if it fits.

So you have cathedral port heads...do you have a gen 3 or gen 4 engine? The ecu that you use makes a difference as well...all this is tied together and needs to be considered as a system.

Realistically speaking, what all effects would the intake manifold have between the gen engines and types of pcms besides the intake port fitment.

Gen 3 engines used the 3 bolt TB and the gen 3 ecu can do cable TB or DBW. Gen 4 engines used the 4 bolt TBs and gen 4 ECUs all had DBW, without the option of using a cable TB...
A used LS6 is probably the best option for a 3 bolt low profile intake. LS1 intake has the same figment but makes less power, but that may not matter much with boost.

I'll probably end up with an LS6 intake. I wouldn't mind an aluminum intake manifold, but I am not sure how much heat soak issues those have. Was really considering the FAST intake, but seen enough people blow them up with boost that I don't really want to risk that expense.
With the LS6 intake, I will probably be able to use my gen 3 TB on it as well, so that'll keep things easy to swap over.

My friend has a spare LS6 intake manifold with a maybe quarter inch square section missing from it. Would it be crazy to think that plastic welding that area up with a much larger piece on the outside of the intake manifold cause a problem?
I've seen several guys put large holes in their truck intake manifolds to shave/clean up the top and then plastic weld everything back together without any issues.

Another thing to consider is MAP sensor placement. LS1/LS6 is in the rear...LS2 is in the front...
