not only is it another possible way to do it, its the proper way. hope that tech certification means something in the end.

doing what you have done to the intake is OKAY, but the intake is not where the weakest airflow link is.
HINT: its allin the heads!
i think your observations werethe direct result of theplacebo effect. if you had a vacuum leak to begin with, you cant compare the truck before to the truck now. what you did to the intake was enlarge the openings of the runners which creates a lower velocity of the incoming air. while the effect is not as dramatic, what you are doing is essentially starting to convert a dual plane style intake into a single plane type.
had it been my engine, i would have left the intake alone and paid attention to the cylinder heads. the stock intake manifold flows plenty of cfm to supportthe vast majority ofstreet applications

BUT: this is a free mod!
A person can easily spend $1200 on heads and although they would make better power than cutting the runners, thats a good chunk of money. We both acknowledged that we weren't sure how much we got from the cut due to replacing the plenum and gasket. I feel like it made a difference and with the price just being labor (& little frustration
) it was worth it for me to do.

Yes, heads are an area for improvment...
A co worker of mine is a professional engine builder, he knows these engines very well...
He ports heads, builds engines, ect ect ect...
He said that the runners are too long in these intake manifolds himself... he told me exactly why and gave me all of the little details in engine building talk... I dont remember it now...
Also, the way that silver cut his runners was indeed the "proper" way... weather it was the "proper" amount or not im not sure of...
I talked to this dude about this very thing yesterday becasue I plan on doing it soon... he explained that the way/angle that silver vut his runners promotes the best flow for these engines... he has tested over 20 veriations of identical intake manifolds on his flow bench...

That is good advice about the heads, and I might add that a cam would open it up more than this mod also.

go to the machine shop and ask for a bowl blend, a valve job, and have them port match the heads to your intake. that should be around 400-500 bucks. THAT is how you make horsepower.
andwhen you decide to throw a cam in it later, you wont be disappointed.

If you get a chance could you ask him to explain why that cut is the way to go. And maybe what angle/depth he found to work the best. Oh AND where it effects the powerband. I've been looking for a little more input on runner cutting. thanx

if you are so dremel happy, take off your heads and blend the bowls. much more power for just as much if not less, cutting time.

RE: Kegger Intake Mod DIY
I'm not going to say that heads arn't a better improvement because they are. You have good ideas but I am not about to spend five to six hundred bucks on factory heads that are prone to cracking. KRC 1.92 heads $1500, Mopar R/T bare heads $900 pair, Edlebrock heads $1400. Since my intake was off those handful of ponies were worth it to me. Although I wouldn't be completely upset if my heads cracked when I have the money to replace them
