Poll: Heads/Cam or Supercharger
i know there is a thread that says something about the gas miliage with a turbo, that you get tiny bit better gas mileage becuase of better efficiancy, something like that?
so woundnt a head cam car be less gas milaege?

lets play devils advocate and say they do, you gotta sacrifice a ton down low to make it up top plus have a shitty idle.
stock bottom end fi cars have gone as high as high 500's/low 600's at the wheels.

you dont need a ton of torque when you have 4:10s. the gears will make up for the loss of torque. my buddy with a torquey 2.8 pullied cobra found out the hard way. 4:10s are aweesome with a 6 speed, you can actually use 6th gear.
"shitty idle" thats your opinion..some like me, love the thumpin idle while some dont. im gonna miss the pounding idle of the H/C setup.
with a GOOD H/C setup....meaning all the boltons, good heads like afr 205s nice sized cam and the 90mm lsx setup and 6 speed car should easliy see 450rwhp.
its been said a trillion times before, dont get caught up in PEAK numbers. compare the dyno graphs of a stock bottom end 8 psi supercharged car to a well setup stock bottom end H/C car.....who has the better curve?
ill say this, it is alot easier to get into the 10s with a turbo or supercharger and still have a full weight, stock wheels, nice driving car but you will need a forged bottom end to play it safe because you'll need more that 8psi ( yea yea i know some people are brave and are doing it on a stock bottom end). with a maxed out 346 H/C setup running stock 17" w/ slicks in the rear, full weight, bottom 11's will be hard to be. if you want any faster your gonna be stripping some weight off the car.

the forced induction car and your point was ?
and you don't need gears to help the motor stay high in the revs with fi-yet another bonus.
this is apples to oranges.

Everyone has an opinion about how to make HP/TQ and good track numbers > bottom line is, if you run more than 8psi on a stock bottom end and don't spend the $$ for a good fuel system > 
I have a blower set-up with nothing stock (internally) and prior to that I didn't and ran 10psi for about 10 seconds and
Either way you do it > don't look for short cuts

Show me a H/C car that still has exellent street maners, no drivability issues and is making well over 600HP at the crank.

I choose high compression heads/cam to make 450-480 rwhp then forge the bottom end, upgrade the fuel system and spray it.
No, not really. With proper suspension, minimal weight reduction, rear end with proper gears, clutch/converter (in other words supporting mods any car needs) bottom 11's or better with heads/cam is fully obtainable.

my good friend here is running 11.20s CAM ONLY A4 with minimal weight reduction. Another friend in his 98 TA ran 10.93 with a small cam by todays standard and 150 shot. Take it for what its worth. Decide on your own which way you want to go because there is just about an even split on which way people on here would go. Do what YOU want and enjoy it.

Why would you buy 17" wheels to put slicks on? You don't put slicks on your stock wheels because they aren't a daily type tire.
Guess I'll do some searching in the 10/11 second forums later.
I personally know one person running 11.2's cam only. Why are you stipulating such a strct "full street setup"?

with all the cars on here, isnt there anybody with a 346 with a top of the line H/C/lsx90mm setup that would line'em up with a 346 8psi supercharged car? thats a race i never saw and im still waiting to see.

and you dont need boost to melt the pistons in your stock bottomend car with H/C car - yet another bonus.

As for low down grunt, well obviously an FI car should produce more. BUT as a centrifugal blower is rpm dependant, it may not be by much, also if it takes until 2000rpm (this is hypothectically speaking) before any significant boost is acheived then n/a and FI will be pretty close. If the FI unit is low CR it may well produce slightly less torque to begin with.
Gears - these will help over come any lack of low down grunt, and with a H/C it will also be beneficial in the higher rpms. If the FI car is still running a stock cam the higher rpms will not be its most preferred place.
Apples to oragnes - Don't be silly, its the same car with the same motor and both/all mods can be done to it.
If its a road car either setup can and does work well.
Apples and oranges would be comparing a sports bike to an 18 wheeler, NOT a slightly different solution to the same question regarding the same engine in the same car.

The first part
the forced inductin car

Think of it the same way as if someone back in grade school said "I know you are but what am I?" See how you can have both a statement and a question in one sentence??

With blower you may have new issues.... belt slippage and cost. downside
I have a Vortech on my 04 GTO which is my daily driver. Only other engine mod is the exhaust (jba's, RT's and a Bassani) and it drives no different than stock under part throttle. It was tuned Friday and it made 480/450 on a dynojet.

well i wouldnt buy 17" wheels but if my car came with them...oh wait...it did, just like all ws6's and SS's. whats wrong with running MT et streets? yea yea i know their not a true "slick" plus i dont drive my car in the rain.
im not saying there isnt any full weight, 17" wheels with et streets/DR's, 346cid, H/C, 93 octane in the 10s, but i would love to hear more about them. let me know if you find any cause i havent.
Why are you stipulating such a strct "full street setup"
because thats what really impresses me.
