will 3.73's help me?
 

I have a 224/cammed full weight 99z. I have a 3200 conveter and 3.23 gears. Do you people think if I installed some 3.73's would it drop my 1/4 time?

what do you run now?

My fastest time was a 12.5@110 with a bad tune. I am wondering will the 3.73's drop me down a few tenths?

A bigger stall will help more;) On the gears going from 3.23 to 3.73 didn't help me any, but I still have the stock cam so their may be some gains with the 3.73's and your cam :confused:

TTT for ya.

The gain will not be very noticable. Go with a bigger stall. Also look into a better tune. Do you have all the supporting mods to compliment the cam? Your times seem a little off.

what are all of your supporting mods?

all free mods, stock Ls1 intake and TB, mac-midlengths/oryp. I've seen people with 3200 vigilante do pretty good 60ft. my 60ft are 1.76 on 20lbs of air on nittos.

you can't be running in your 11.4's with a stock cam car :eek2: My best 60 ft. is a 1.76 with the 3200 vigilante with about 18-20lbs of air on nittos.

Ahh yea I can. There are plenty of stock cam/heads cars in the 11's

save the money and get an ls6 intake. Help that cam breath a little better.

Just my .02

Are you stalling that vig up or flashing it off the line? I would save your money and get some suspension parts and a retune.

before my cam and ls6 intake I was running consistent 12.8s with 3.73s and a 3200 stall 60' were 1.9. Put the ls6 intake on and I dropped to 12.3s and 60' 1.7. I guess I finally hit that good combo. Weather conditions were similar on both runs! I think once you start getting into mid 12s, the ls1 intake becomes very restrictive and really holds you back. I would look into that if I were you. Then maybe a bigger stall.

yea there are quite a few cars SI NA in the 11s. Friend of mine, Silent But Violent, ran 11.3s all day long on stock internals na! Magnus cut a 10.9 SI NA.
...amazing what weight reduction and the right combo can do!

Thanks for the input. How does your car run on top end with the 3.73's?

still pulls strong on top end...not sure what rpms im turning though! Ill find out soon as the local track opens back up.
