I need some pictures of your intakes. i think i have the most restrictive one here. i really should make or get a better one.

here is something that will help you

http://www.gmtips.com/3rd-degree/dox...-port/port.htm

 

in that diagram that says runners. I just cut those out and grinded them back as far as I could. do this at your own risk.

 

I think by intake you mean the intake tract?
well heres mine:

 

85 TPI --- A few things have sinced changed but this pic shows the tpi well.

 

I think he's talking about the air filter ducting. Not the intake. If so, yes his is one of the most restrictive. - what evr you do, don't use metal unless it's well painted/powder coated. The heat sink of polished is horrid...

 

 

I got a new powermaster 140 amp alt on there now aswell ...so it's a lil less ugly

 

Ready for it's first start.

 

SLP runners.

 

 

Geese man , mine and your cars are VERY close in every way I made 251 rwhp and 318 rwtq( 083 heads and ZZ4 cam) . With the same intake you have ( I am above your origonal post) ...same goodyear blue hoses and we had the same idea of buffing the fins and podercoating the intake.

 

heres mine before i began the process of putting on my converted lt1 intake.

well u said tpi intakes so heres mine-- ACCEL superram base

in process of port job

 

Here'a pic I found just after i completed the tpi swap. Although it's not going to look that way after x-mas. I am looking to get a super ram set up come Jan/Feb.

 

what are you useing to port the intake?

 

Here is mine...

 

Sorry for the late reply, but yes I did.

 

Here's mine:

 

Here's Mine

 

 

 

My Intake = Port Job

 

Hand polished before i painted the runners black.

 

I have a little push behind mine

 

did opening up those 2 ports into one make a diffrence?

also do you have the big runners?

 

I did the same thing and it just seemed right to me because the walls are restrictive.

I have the stock runners w/305 setup.

I am not telling you to do it. I am only saying it did not disrupt my idle and because I did alot of mods with it I could not tell you about the performance enhancement

 

Most people would say that it benefits topend power, but on my LB9 i could break the tires loose from a dead stop after i did that, where as i couldnt break them loose before.

When i cut down the EGR walls behind the throttle body it did help out on the topend.

LB9 + 700R4 + 2:73 Rear + New Tires =Great Traction

 

well a L98 + 700r4+ 2.73 rear with new tires i still have no problem lighting the tires up from a stop.


I would like to keep the TPI look but i want to make some decent power with it . My gn puts down 350 @ the wheels on pump gas a low boost. i ould like to have the maro get close to 300 @ the wheels.


i'm going to the track today and run it 1/8 mile i'm thinking 10's here i come lol

 

That and 45 more cubes will make a difference compared to a stock 305.

 

 

Here's a few more...

i think it would be interesting to see how much of a difference all these different intake/runner combo's make

 

Ours look pretty similar!

I haven't decided if I'll keep this air ducting or not. My truck doesn't need more than 4500 rpm anyways, so I'll probally leave it, and slap a paper filter on the end. Looks very nice, and it's open is directly infront of a big 3 - 4" hole in my rad where my factory air cleaner used to hook up to get fresh air from the grill

 

Luke, are these the Billet Specialties valve covers?

 

Cant get more restrictive than stock

 

heres an old pic, empty engine bay right now i will have some more higher quality cleaner bay pics soon

 

heres mine, old pic but I will update soon, engine bay is empty right now finally, will have some higher quality cleaner engine bay pics soon

 

Just finished build tonight.......

 

here is mine

 

One of mine, AS&M runners, ported plenum
