Look what Santa dropped at my front door today. Now I gotta do some research and figure out how to tweek this bad boy.

I wish you luck. I found the manifold to be fussy in terms of mounting and while I should have tried longer, did not make the power I expected. They really like >displacement.

Are you sure you need that setup? Email me and I'll send you my shipping address for "proper disposal" of gearhead paraphernalia.

I think port matching really helps these intakes out, so that's my weekend project, then it's tune time.
Hey Rick, I'll send you some of my slightly used "gearhead paraphernalia" from the basement if you want, I have all sorts of neat stuff that's been collecting dust for 20 years or so. In fact, I'll even pay Freightliners fare for the 3 trailer loads.
Of course we must define "Gearhead paraphernalia" as "Anything a gearhead collects and cherishes to the point of "disposal denial".
So that includes:
Fish tanks, dog crates, screening, old lawn mowers, odd wheels, green carpet, rack mounts, old ham radios, etc...

I don't think green carpet should be included. That's a standard household item. Some of the rest is a stretch....but you can't stretch to green carpet.Originally Posted by DaleMX

I don't mean to rain on your parade, just don't want you to beat yourself up if you don't see a big improvement with the FAST manifold. Unfortunately, this manifold doesn't seem to do much on stock displacement engines. We got about one or two horsepower over an LS6 manifold on an LS6 with a 220+/- cam, headers and exhaust. A bit of tuning brought that up to about a 12 horsepower increase, but that's an apple to oranges comparison, because we didn't have time to tune with the LS6 manifold. I also have a friend who has used these manifolds on a variety of engines and his best results were on a stout 420-incher. He saw 10-horsepower over an LS6, but it took quite a bit of tuning to get there. Good luck with your project and keep us posted-- maybe you'll find the secret.

Odd wheels and lawn mowers sound interesting. Fish tanks, dog crates - anything critter related you can keep.Originally Posted by DaleMX

Those manifolds are very tricky to seal properly.
Strange but those manifolds make a bit of power up here halfway to the clouds course thats with cam and headwork. Std tb and manifolds are restrictive as witnessed by the falling manifold pressure over 4k dont have that problem with the Fast.
\"You Can Never Have Enough Horsepower\"
My main reason for the fast was because I cracked my LS6 intake, repaired it, and it broke again. I have planed on a 402 in the future so I decided the fast 90 was the best decision.
There has been some good gains with porting on stock cube engines, but the correct porting is a science. Tony Mamo over on www.LS1Tech.com has shown some real promise. I am going to contact him for details before I do the 402. So for now I will just port match to my Stage II heads.
For the sealing, I bought the thicker o-rings that BYUNSPEED sells, and I'll flatten out the bolts in the valley pan. Hopefully the thicker 0-rings will do the trick though.

These are the results from my 346cu,C5. The intake was not port matched until the heads were redone. The results are good but is not all that unusual.
Why are you flattening the VC bolts, didn't the setup come with the flatter bolts?
I believe the warped intakes are out of the system.
Take your time and watch out for the oil pressure sender. Suggest you put a little clear caulk under the MAP sensor.
