350-360? without heads or cam you would be pretty much hard pressed to hit that.

And that might be too high as well. you would have to have every single bolt-on including electric water pump. Is there a reason why you dont want heads or cam anyway?

You can run a cam only setup and that will get you your 400 rwhp mark. You can take a few routes from the fork in the road that you are at. But only after you answer this will you know what you want to do..

Supercharger?
Nitrous?
Turbo?

If you plan on any of those, heads and cam are still an important factor, but are not near as radical as on an N/A setup.

With a supercharger on a stock car it will net you 450+ on low boost.

You can see up to 80+ rwhp on a good H/C combo. So you are planning on staying N/A. That actually tells me what other things you might be looking for in performance out of a naturally aspirated motor.

I would suggest you check out the stickies for more of the information.

But to get you started. You could run a huge cam on stock heads with new springs and retainers with hardly any problems at all. You are going to want to get this thing tuned even with a bunch of bolt-on's.

But Your best bet being an A4 would be a nice TQ converter. I would say that this is going to be one of your first major mods.

thanks for all the help and sorry to keep asking so many questions but i have a few more. where could i go to find a H/C combo and involving the torque converter which would u prefer since its a daliy driver. how will it affect my daily driving? and i understand it helps u get off the line faster, but do u still drive the car normally? never really understood that much about them. sorry to be so clueless to all these things but i guess i gotta start sometime.

Lol, nah its cool. BTW i am an M6.

here is a really good explanation/write-up on how a stall works. http://www.bankspower.com/Tech_under...rqueconver.cfm

I would check with just about any of the sponsors over here --------------------->

But if you want an opinion...I would say call Patriot ,Thunder, TSP, Futral, Speed Inc, MTI...ect for the best qoutes on prices. They will also be extremely helpful in having you chose a combo that will yield the results that you are looking for and even tell you what the appropriate stall would be depending on your selection. BTW: There are a lot of good prices on heads right now. Patriot has a pretty slick deal on some cast LS6 243 heads that are 100% CNC'ed.

You get the entire valve train with it. You need Titanium Retainers if you are rockin a big enough cam. I am not sure if they throw in pushrods or not. But definitely a good deal! But I bet if you get a package from them they will give you EVERYTHING you need.

With a good cam & ALL the bolt-ons you can hit 400rwhp, or very close. A stall will make the car faster, but you will lose some dyno #s because it slips more. I have a Yank SS3200 & for normal driving it's almost not noticeable, but it dropped 3/10ths off my et (& cost me 10hp on the dyno).

You can get better track results out of a bigger stall, but it does affect how the car drives in town. If your car is loud (like mine is) and you have traffic ***** in your area, revving to 3k at the stoplight is not a good thing!

TR's 224 cam seems to be pretty popular, makes fair power & is easy to tune. GM's Hot Cam makes more power than many like to admit, but it's not a good idler, especially without a stall. And Cam Motion will grind a cam spec'd to your car for a little more.

I'm hoping for 400 at the rear with my heads/cam combo. Even in a M6 you wouldn't be close to 400 with just bolt-ons unless you consider heads a bolt on.
