head\cam vs. FI ok im at the point where im either gonna go forced induction or head\cam... as of now my car is low 12.1-11.8 car with a 1.7 60' tractionn is a big prob already with lots of suspension mods and 11 inch wide nittos so i cant really use any more off the line.. as of now ill reck a stock t\a off the line but from a HWY roll im not that much faster.. i figure this is where i need to make up my ground. the car is NOT daily driven, hell its barley driven once a week! the head cam package id probally do is: ported n polished ls6 heads with fm 14 cam or the FI setup is ATI @ 8psi. I know u all are gonna say do em both but i race the **** out of my car and done wanna have a max effort motor .. that said id like to put down over 550 crank and dont wanna rev past 7k with street manners (by street manners i dont mean like stock just not stalling or overheating)

what about an ati blower @ 8psi an a big blower cam ???
my whole prob with n2o is from what ive read its alot more risky than a blower.. but im o expert...also i really race the **** out of my car so its gotta be reliable i mean i might go and pull 5-10 runs back to back with just minimal cool down time i dont want a car that needs all sorts of special treatment like race fuel... the way i look at it is since most of my races are not planned street races i gotta be rdy all the time i can pull a "uh holdon while i go home and switch my setup so i can run"

Well i am living with that decision as we speak. I went with heads and cam and im very happy with the way my car runs, but for the money i have spent i wish i would have went with a custom ground blower cam and a blower. I would have made more power and it would be alot of fun to hear the blower,lol. Just for the fact that with the blower set up it will keep almost all its stock driving characteristics and make a ton of power. If you have the money i would go that route. good luck Charles

FI and a cam suited for FI. Nothing drastic, keep it under .600. You'll still achieve your goals, get slightly better results than FI alone, and only add a couple hundred to the price.
If price isn't an option, do the heads to. I would personally keep the h/c portion mild and treat it like a supporting cast for the FI, but I would upgrade them nonetheless.

I have a friend with an 530 crank hp svt and he is costantly icing his motor to avoid heat soak, he said as a street driver he notices a lot on the street as well, money set a side how can you argue with a blower car for fun an tunability and WOW factor,, I have a just purchase a H/C for my c5 though, but I want the mean lope om the street. I have already done all the bolt ons that I can to acheave 530 fwhp for about 10k in mods, if I had it to do over I would have just bought a blower and a good clutch for the same price and called it a day! Plus much easier with a blower to go back to stock if you sell the car.

$$ no object, I'd do forced induction.
I just did heads/mild cam and love it. But, there's no wow factor.
It's nice to drive like stock till I nail it, but the average guy on the street doesn't know what's in there. Something to be said about the "wow factor."
In two days, I've already had a couple people say, "it doesn't sound any faster." That is of course till I took them for a ride.

really appriciate all of your opnions keep em comming! the car will probally never get sold so i have no concern for returning it to stock, as far as reliabilty i want the items that will perform all the time not just when iced down.... basically i know i could but a trex cam and spray and rip *** but for how many times.... i want a proven setup that can be beat to **** and still perform in hot weahter cold weather.. money is not unlimited but id rather save then buy something ill just end up selling.. if i did a cam blower car would it easily become heat soaked? or can i get away with hot lapping it a bit.... also with a large cam and ls6 heads how long would the right set of vavle train compodents hold up???
