What New Intake Manifold to get

I was looking at a new intake manifold for my silverado. just to get a little extra out of it. right now i have an edelbrock performer. with a holley 4 bbl 650 cfm carb. what should i get for more power. i was looking at a tunnel ram from edelbrock. but im not quite sure yet cuz id have to buy 2 new carbs too.

Uh... how about something we can use, like cam, compression, cubic inches, intended use...

A street engine never needs more than a performer RPM. Seriously. Especially with a 650 cfm carb. The intake has to match the powerband of the cam or you'll lose acceleration.

intakes don't make any power,,,it's just a pipe...

bigger simply increases the motor rpms operating range with more total plenum area and runners demensions....

if your cam is less than 5500rpms initial HP rpms peak,,,leave it alone...
a 4400lb truck needs all the low end TQ possible from higher Hg and velocity when accelerating from a stop sign...

my$.02:
even if the cam peak is 6,000rpms I would leave it alone if it is a daily driver...
a swap would make it maybe/possibly 1-2 tenths quicker max at the strip due to the 4400lbs

You`ve been swallowed by mores law: "If some is good more must be better"
Tunnel rams and dual quads are made for upper RPM horsepower and not very practical on street machines, not to mention the tuning headache 2 carbs cause. Many novice hot rodders make the same mistake when it comes to cams and intakes. Curtis said it right, the combo must be matched to make max power. You can`t count on one part to make the difference. In this case if you have a next to stock 350 that won`t see over 6000 RPM what do you need a tunnel ram for? it`s power band doesn`t start until 3500 RPM and goes up to 9000 RPM makes it lop sided for a street machine.

the sticker weight is not correct,,,
go to a concrete plant/dump/hiway trucks scale/whatever and get it weighed...

DoubleVision's post does say: "IF" your motor is nearly stock...
so you are the one that needs to get your sh## straight...

Before you go being a complete anus, you still haven't provided us with ANY information that might help make the decision. How can we get it straight when you haven't told us anything? All you did was ask a vague question, got a cheerful and helpful answer, then swore at us cause we suck. Sit 'n' spin, jerkoff.

Cam
exhust
compression
head flow
intended use
converter stall
axle ratio
tire size

my tires are narrow as hell
its a daily driver

not sure about compression
headers with glasspacks

im sorry if im appearing to be the dick in this but calling my motor next to stock as insulting to me.

No, he said IF. Learn to read. You have no reason to lash out at a respected forum member, noob. His advice is spot-on, his repsonse was respectful and helpful, and until you tell us the specs of your truck, you are just continuing to be a complete spooge stain.

My guess is the truck doesn't even exist. You've posted several times about a magical 3800-lb truck (what, is it all aluminum?) but given us nothing but grief.

Grow up.
