would these work on a LS1 third gen swap and woudn't they be better than stock?

 

They would work but the 01-02 maniflolds flow basicly the same so there is no performance increase by going to shortys. Your only option for that is long tubes but no one makes them right now. Hawks is suposed to come out with a pair here by may/june other then that your only option is to take some regular hooker sbc LT and cut them to fit lst flanges that you can get from GMPP.

Shorties are a waste... Stock manifolds flow well enough

 

Another alternative would be to run the LS2 stock manifolds. They will designed to flow much better than the LS1 manifolds.

 

ive seen + 9whp on a dyno going from shorty headers to a stock z06 manifold......

manifolds teh win

 

Saw hawks has longtubes now!!!!!!

 

Yep saw that today, called them on it and they were fitted on a car lowered with sportlines. Also they have y-pipes made to fit the spohn tq arm with drive shaft loop. This def. made my day and prolly will be ordering them here in the next day or so. Thanks HAWKS!!!

Justin

 

how much. cant wait till monday to call them and find out.

 

750 for the headers, 1000 for headers and off-road y-pipe, and 1200 for headers and catted y-pipe. Headers are stainless steel so prices are about right(qtp and kooks are 800).

Justin

 

not too bad at all.
thanks!

 

I'm all over the Hawk's setup like a bad monkey!

 

yea planning on ordering there headers w/y-pipe and there k-member monday(can't wait). When i talked to them yesterday they said that they fixed the issue with the alternator hitting the stock steering with the k-member which made me happy. Also i wonder why they went with 2 1/2 inch y-pipe and not a 3 inch all well could have been for clearance.

Justin

 

Great ! I'll make plans on sending my k-member back and getting that corrected ,too.

 

OH YEAH I will be calling Bruce this week. I just have two questions Do they come with O2 bungs and will they fit around Kenny Brown SFCs.

 

Just ordered Hawks headers and y-pipe with cats, and his tubular k-member. Bruce is an awsome guy who answered all my questions and was very helpfull. I would recomend him to anyone.

thanks Bruce

Justin

 

thought they were gonna work with the stock k-member.. guess not

 

he assured me that the headers would work with the stock k member.
the car that was used to make the headers had a stock engine crossmember. this is comming from hawks.

 

Yes they do work with the stock k-member but i ordered the tubular one cause i wanted it . I looked at it and if i went with the stock K-member i had to buy the ac relocation bracket and that thing is like 250 so for 200 more i could go tubular so i figured why not.

Justin

 

As soon as some one gets them and gets them on I would love to see pics!

 

yes this is pretty much the last straw... I need to start making serious plans for the LS1. The only part I still want to see is a k-member from Spohn and I'll have my dream setup.

About those LTs, will they need to be coated or anything? I currently have SLP headers on my 355 that were supposedly 'stainless' but gawd are they rusty already....

 

and yes! pics! pics!

I wouldnt hold your breath on spohn's k-member, i talked to him about 3 weeks ago and it didnt sound like it would be out for a while.

 

BMR's k member is just about out. the regular k member for an SBC is already being sold.
looks pretty beefy too. its 4# heavier than a PA unit. not too bad.

 

They are stainless, 409 stainless, a low chrome, easily weldable, cheap alternative with less corrosion resistance than other "stainless" materials, only sightly better than galvanized. 409SS will turn a brownish color with slight rust but it shouldn't rot. Suprisingly, they use 304SS for the flanges for "better sealing and long life"

 

Any one get some of the long tubes in yet!!

 

other than the test car, i dont think any have been shipped out. none prolly even finished production yet.
im interested in them for sure. im no pig, so ill let someone else post how well or bad they fit.

 

Just wondered

 

Spoke to Bruce Hawkins earlier tonight.............

Yes there are O2 bungs on the headers

He has 10 sets of headers coming arriving in 3 weeks

He has 10 MORE sets of headers coming a few weeks after that

He said he hasn't dyno'd any of them yet, but he got the car back that they used for making the jig, and he's guessing at least a 25-30 hp rear wheel gain on a stock engine with these headers and y-pipe, based on how badly it beat another 3rd gen stock LS1 they had.

 

Wow, cool. I was thinking of selling my thirdgen to geth a 4th. But now I'm seriously thinking about staying 3rd and going with the LS1. There's awesome aftermarket to make = power. Granted expensive. But this engine favors a 3rd gen. Downright sexy!
