As a new year resolution I decided to have all my stg2 heads cnc'ed by a company by me on long island. The reason is to cut down big time on leadin and wait times. My Goal is to have a series of my stg2 heads on the shelf. The cnc heads are a version of my newest stg2 port with the 2.040 valves, these heads are improved mainly in the mid range lift areas from .300-.500 and improved flow overall through the ls6 intake. I am running a GP on the stg2 cnc version for 1280 outright {no core charge}. look in the GP section for more details. I have 12 sets now being cnc'd that should be ready by Jan 19th

coming this month, my new 80mm throttle bodies and ls6 intake manifold porting. The tb's will sell for 289.99 and the ported intake will run 499.99. the Two combined are worth in the 20hp area on h/c 346 engines and more on larger cubed gen 3's

feel free to email me at sales@absolutespeedls1.net with any questions

Way to keep on top Jay... Let me know when you want to try out the new Intake/TB combo on a stroker...

 

Interesting hot new products.

Any pictures you can share of the new TB?

I'll be looking for a new one or ported one in the near future.

Alternate title for the thread: The LS6 intake Strikes Back!

 

Great to see the new developments Jay. I will be contacting you in a couple of months for a set of 5.3 S2's for a TR230 cam, a ported LS6 intake and a TB. I'm sure with your heads and this cam I'll be able to finally get the numbers I want out of my car.

Will your ported LS6 intake sell on an exchange basis?????

 

Sounds great Jay. I just wished I would have known about this sooner. I know some of the guys in the club are very happy with his heads.

 

great news Jay. Looks like this upcomping year we will start to see you more at the track.

 

Would like to know the same and if so what the exchange price???

 

Wow this sounds like a VERY tempting deal.......I bet those heads would go nicely with my TR230

 

do these come with springs and retainers?

 

Jay it sounds like a sweet deal i'm also looking foward to seeing you at the track this year

 

Yea Jay, how about a exchange price or how much if I send my egr provision LS6 intake to you to get ported and I'll get your T/B at the same time?

 

Ive been getting alot of questions on the 2.04 valve. The 2.04 valve I feel is the perfect size for the port and the stock size bore. Not only does flow go up but keeping the cross sectional area near stock makes velocity in the runner increase also, while I can get flows near the same with a 2.02 valve, the velocity and rate of increase while the valve opens improves most of all. I also made a few other changes in port design and valve job that improved low and mid lift flow. The 2.04 valve will work with any cam, big or small it likes it all. Listed below is the corrected flow numbers off my superflow at 28 inches of water depression
lift- int - ex
200-153-117 stg2 5.3l 3.9 test bore
300-207-171 1-3/4 ex test pipe
400-257-204
450-278-214
500-291-222
550-304-224
600-311-229

best of all the numbers through an ls6 intake
200-153
300-204
400-247
450-261
500-272
550-279
600-283

 

Jay I wish I had the money to pick these heads up right now. I will be getting them soon though.

Joe

 

now for the intake, it will be on exchange basis. It is alot of porting in hard to get to areas, also the flow numbers listed above is through an untouched ls6 runner. I will get pics on here of the throttle body in the near future.

 

Have you got flow numbers thru one of your ported LS6 intakes? I'd like to see how much that is worth in the flow dept.

 

Nice work Jay! I assume you are finishing the heads up by hand after the CNC work?

 

Will the TB work on a Corvette?

 

I'd like to see flow through the ported LS-6 intake to. What about exaust flow without the pipe, for comparison..

 

great to hear Jay, cant wait till i got the $$ to get a set for my car
