Hi everyone. I'm looking to throw a direct port kit on my 12:1 416 LS3, which currently has a ported FAST 90/90 setup (cathedral port TFS 225's) . Currently makes ~530whp on motor. Since I'll be sending an intake off to be plumbed, I'm considering selling the 90/90 and going with a different setup if worthwhile.

What are your thoughts on going from the ported 90 to a ported 102? Other intake recommendations? If I'm leaving ~20hp on the table with the current setup this may be worth it, if not I'll leave it as is. Any info is appreciated!

So if you’re running a 90 you must have cathedral port heads?

Sorry, wasn't thinking, original post edited.

The 90mm TB may be good enough for your 416ci.......but I'd still go with a 102 TB and intake.

But hell.....that's just me.

If you’re running cathedral ports you don’t have an ls3. Regardless a ported MSD would likely be best in that situation

I dunno.

I've seen a few people here with LS3 blocks (stroked and stock) and cathedral port heads......you haven't?

It's definitely an LS3. Not uncommon, several posts on here about it.

Yes but I don’t see how that’s an ls3. And it’s confusing when you’re trying to find the best intake because it doesn’t have ls3 heads. It has cathedral ports

C'mon bruh.....it's obvious he was stating that he had a LS3 short block.....

He said he has a 416 ls3. He doesn’t. He has a cathedral headed 416.

That's EXACTLY what he said......a 416 LS3.......which currently has......

But it's all good, Hammer.......you have a great evening!!

He edited that after. Regardless. Since it’s a cathedral
Port 416 I’d say a well ported MSD is the best choice

By all means, continue arguing semantics.
