just like the title. just wanted to know if anybody has a video or a sound clip of a ls with 403's in it. does the engine have a deeper tone or higher or just sound pretty much stock. searched it and couldnt find nething. thanks

 

I kinda wondering too, but not about the noise of the engine, i'm more worried about
how the idle will sound when tuned.

 

the idles with the 403's should be fine if tuned right but the 404's is where the idle can be a problem

 

night bump.
just wanted to see if the late nighters got anything on this

 

i have 404's and runs very good and idles nice....
about 750-775 ish rpm

 

any difference in tone when you get on the gas a little

i have 404's in my car. idle is nasty at 675rpm where i keep it, but is smooth as stock if you hike it up to like 1000rpm, maybe a bit more. it'll idle really really rich if you don't have safc or something like it, so badly in fact that i strongly recommend nobody get them before getting an afc. also, idling that rich makes it nearly impossible to get a steady idle below 1200-ish rpm, and with cams that big you'll want the afc anyways. in any case, i haven't even noticed a difference in sound at all, from off-idle to redline, in the exhaust note. only way anybody can tell w/ my car is wait for the tach to swing past about 4000rpm, b/c you better hang on!

 

I had 402's in my car. My friend had 403's and 404's tuned. Couldn't tell the difference at all. Just felt the power just a little bit more. Idle seemed stock.

 

Id love to go record a sounds clip for you, but i spun a bearing...she dont run no more

But i did notice even after 3 valve adjustments, that the valve train is considerably louder than most cars...but its an LS valvetrain and u cant expect it to be quiet...also when tuned, it lopes a little bit...but a crisp lope, not a dying lope like some cars...

 

climaxpinoy sent me his vid of his car. his car sounds abso. wicked from about 6 grand til 8 grand which his shift point was. and from the vid it pulls like a train. very nice
if nebody else has a vid or is gonna record one id greatly appreciate it. i just wanna see what im lookin forward to

 

well i have a set of 403's on my LS and u can definitly hear a lope on them. my idle is set at stock around 700-750. i have 2 1/2" N1 exhaust and u can hear the lope from inside and outside the car. it's not a crazy lopey idle but it's still a lope. Makes the car sound really aggressive at idle. as soon as i installed my cams and started the car up at my friends shop, he said he could definitly hear the cams. then when i took the car home all my friends said the car sounded mean. i love that sound!

How much difference did it make in power?

 

Right now the car is untuned but u can still feel the power after 3-4K rpms. thats where these cams shine. once i install my PR3 pistons and get it dyno tuned, the car will be run n much much better.

on the side note, after i installed these cams, it shaved almost 0.5 sec's off my 1/4 mile time and the car was run n really bad too that day. before w/o the cams the car ran 15.92. It ran a 15.5 after the install. these are horrible times i know, but i had played around with the cam gears before i went to the track which i shouldnt have done. the car had trouble stay n on. it would shut off on my alot during idle. i went home and set the gears back to stock and the car felt alot better.

Cant wait to install the pistons and have this sucker dyno tuned!!!! and then with a B16 tranny i'll be run n really good

 

let us see!!!!!

 

i'll have my vid hosted by tomorow morning

 

i want to install 403's on my ls. do i have to get anything else besides the cams? i only shift at 7000 so i dont think i need a valve train...do i need vafc to run or what? what about cam gears?

 

evevn if ur not gonna shift past 7k, those cams are still very aggressive.. i highly recommend the springs and retainers....
cam gears arent necessary, but add a lil more to tuning...
as far as a safc/vafc, i'd recommended it for tuning. jus get a good tuner
i have the 404's and people say u can't even get it to idle well at all, but mine idles like stock.
so all in all. good tuning

 

is it worth the money for the cams and valve springs and retainers?
