Well I know you've already decided on GTP's and I understand why. Only thing I was going to say is that if you think TEA hasn't put out good numbers, well that's not exactly right. Their C5 with Stage 1.5 5.3 heads and their nearly stock bottom end 346 ran 9.87@138mph so I think their numbers are pretty good if you ask me.

 

BTW just for the record about TEA making power...the TEA 2.5's made 690rwhp with NOS on a factory short block and much smaller cam and intake not up to LSX standards compared to what Monkey is building. The TEA 2.5's were a 90rwhp gain over the prior 1.5 TEA heads on the gas with no other changes. Add in Monkeys extra ~50 CID and well you get the pricture...750rwhp? Who knows...

FWIW the TEA 2.5's will put excellent numbers agreed Snake...but let's not side track Monkeys thread too much. It's his project and he should build it so he's happy with the part selection and so on since it's for his car.

Monkey what's the set up work out to be a 396 or something like that? I would really want that LSX intake with ~400 CID and that cam and good heads. That will give you way more than the other valves.

Likewise, If you give them your LSX intake to test with GTP might be able to alter the valve job on your current heads to get you max flow with the current valves and/or match the flow to your exact cam and intake. That and a little GTP porting on the LSX for max flow and I think this would be very cost effective way to make the best power with the 2.02 valves.

Of course I'll always be wondering what the TEA 2.5's would have done on your sweet set up

 

it will be a 392. that sounds like another good option black bird. but when will that intake be out? i have to decide by the end of this year on what to do.

snake, i know that TEA does have some quick cars, but GTP has had several cars running mid 10s n/a on the S2 head. i am not naive, i know there are other great set of heads, i just prefer GTP for personal reasons...just like black bird prefers TEA..and others prefer MTI..and so on. i guess it was when i talked to craig @GTP for over 1/2 hour(on several occassions) that i decided this is where my money is going. i guess you can call me an attention *****

 

I think the intake is supposed to be out in Jan of 04, saw a thread about it a week or so ago. Honestly, the LSX is out of my budget so I didn't read the thread too close. Was in the external section I think.

Likewise, with your ~392 cubes, you might be able to get a little porting done on your LS6 intake. I think GTP has done that before for ~400 sized engines. Will cost some bottom end torque and help up top if I remember correctly.

 

hmm, jan 4 huh? but then i would have to get the 90mm TB. damn it, why cant racing be simple.

 

I think the first thing to do would be talking to GTP. I am sure they know more about your heads than anyone else. Get their opinion and sugestions on what would be best for you.

 

i have talked to craig. he given me several options:
1. upgrade to S3 with 2.05(or 2.08)/1.57(or1.6)valves only
2.full out port job with the larger valves and dual springs
3. just get 921 springs and go with bigger cam
4. just get some more port work done to the S2+ heads i have now.

but i am really leaning towards that S3 valve upgrade. i can sell the valves and springs(918s) to offset the upgrade. i have some wheels for sell, if i could get $300 bones for those, i would go all out on the S3 heads(the whole enchilada baby ) and ask craig to get 340+cfm.

 

I like option #2 the best.

 

I have some TEA/GTP S2 heads with 2.02 and 1.57s and we just recently went 10.77 in a C5 with 3.90s. They are consistent and capable.

 

jason, ..i think you are right. i told craig i will stop by his shop after the holidays.

phil, TEA/GTP? how did that work out. is it a TEA head finished by GTP or the other way around?

 

TEA/GTP? damit. now there is another option in LS1 heads. which way will i go know. i think i am going to stick with SMPs. hehehe.

 

good choice
