Since you have a dyno tuned chip, shouldnt you have had your car on the dyno already????
Im going to say that you didnt just for the sake of it. But, im going to say about 310-320 depending on your heads/intake. are they the street heats, the tracks or what? well, i might even say about 300rwhp due to the auto too, but, thats becasue i like to be pesamistic on somethings and not get too disapointed.

are you going to have it dynoed?
 
I will guess around 320, if you have not gotten the chip, a Tweecer is a much better investment, I just replaced my autologic with the Tweecer RT, it already feels like a whole new car.

what is a tweecer?
how much, what does it do, im not familiar with this? i dont wanna have chip custom burned then realized i should have gotten this tweecer.
 
personally the cam and injectors are too small, with that cam the 331 will be done at like 5200 rpm. and the intake should be a short runner type, a long runner will choke it off above 5000.

with your listed combo and the aod I will say 325rwhp and 375rwtq.

get a bigger, better cam , a short runner intake, x pipe with no cats and 30lbers and you could see 400rwhp and 425rwtq.

but if you have to be emmisions freindly than your present setup would be good.
 
yeah i was gonna say with nice HCI on that u should se at least upper 300s..border lining 4s...maybe a littel less with the auto...u will need 30#s..get a nice custom cam..short runner style intake as said above..and u will be set. Matm347 y u saying such a low #? im gettign scared cause i heard that with teh same exact stuff a 331 should only be making about 20 HP less than the 347. how much u putting out? i talked to about the 347 buit i think i changed my mind to a 331
 
Well it was dyno tuned before the 331. I haven't got the 331 in yet but should by Xmas as it being built as we speak. I have another dyno appt on 1/3/03.

The heads are off the shelf twisted wedge and the intake is a steet intake.

What would the biggest cam I could get and still be smog legal and drive ok with the AODE???

I'd be happy with 325 at the wheels for now but 1 million would be pretty cool. I think I'd have to get a Ricer wing if that was the case though not to mention extra stickers and stuff.

All the numbers on the cam are as follows:
Lunati L51014

RPMS 2500-6000

Duration In/Exh 284° 292°

@.050 In/Exh 218°/226°

@ Valve In/Exh .500"/.510"

@ Lobe In/Exh .312"/.318"

112° Sep 108° Int C/L
 
but the big question is do you want to be emmisions friendly?

if so and you plan to run cats then I would go much bigger than the cam you picked or the cats wont live long.

but if emmisions are not an issue then ditch the cats and get a cam around 236/242 deg at .050", 112 ls, .540"/.540" with 4 deg adv built in. and you'll have to ditch that long runner intake for a short runner like the trick flow r series.
 
honestly, your cam is too small. i have a stage 3 tfs cam .575 .594 lift. i have box stock tfs heads too. i was actually going to trade my cobra intake for a tfs street but i heard its too small just like my cobra. also, if i could suggest 30's instead of 24's. more room for growth and you wont have to do it twice. also, with some tuning i am sure you could get pretty close to 325 at the wheels. if you dont have the intake already try for the track instead of the street or for a systemax or rpmII.

good luck to you though!
