HOw could this be??? TEA heads suck according to many..

 

What would the compression ratio be for .030 off of a 5.3 head?

 

Yeah!!! ...how could this be LMHWFAO Vince....

Tom....congrats...nice job

....."and as the believers gather strength, the unfaithfull shall be crushed and destroyed"....

 

kick *** #`s man

Is that cam something you sell or was that customer supplied?
Do you have anymore info like lift and lsa

Thanks

Jeremy

 

Sounds pretty impressive to me.

Really, NE6t9 will be on here explaining it even if it made 430rwhp + it's not a "real" 430rwhp because the converter was locked or something lame like that.

 

According to TEA's calcualtions, it should be 11.4:1. We tuned the car on 93 octane with no KR.

The lift was just under .600, on a 112LSA. IT is a custom grind we spec'd out with Comp.

Sounds great,I have about the same setup.
It dynoed 429/396 threw a 12-bolt/4.10
Cartek LS6-S2 heads/224-228 581-588 113 cam.

Good luck w/her guys...

 

Now that TEA has did it we can believe JS #'s. Just kidding.. Technology is getting there for us.. Thats a big cam though. How is the idle?

 

Nice numbers with an A4. Congrats.

Bruce

 

damn... I call BS cause its no way TEA could make these numbers... espically in a A4! LMAO

Awesome numbers LS1 SPEED!!!

 

 

My old MMS stock shortblock/heads/cam a4 setup made 446rwhp like two years ago, lol

 

Dug the grave for that yet?

Nice ##s

 

I bet he has an aluminum flywheel, those things add 30 to the wheels ya know

 

i would also like to know how it idles. probably as good as my 230/230 111 lsa cammed car! very nice results. that cam sounds like LGMs cam.

 

actually the car has a 12 BOLT,SO EVEN A LITTLE BETTER

to answer a few more questions

-the car idles great for a cam that size
-the car is driven to and from work reg. and get 250+ miles to a tank
-temp was over 85 degrees in shop,and muggy

track times to come

Larry

 

Cool congrats on the numbers. Do you have any sound clips of that thing idling? I bet it sounds nasty

 

Good numbers. Sounds about like the cam I have in our car. 234/242. She's a loper but man she pulls like a bitch up top!!!

Way to go guys!
