PAckage? HEy gUys!
Opinions and suggestions wanted. Want to do a build only changing cam, heads, possibly electric waterpump. WHat is the highest possible power that could be made on stock bottem end with exhaust already done, and not wanting to do a stahl converter?(understands stalhs dont make power)
ALso....To make over 500hp, is your best otpion to go with big cubes? Is it possible with a 346 non-forced induction that is not a full race motor? Whatcha got guys? hit me.....

there are some guys on here that make big power on the stock bottom ends. you should check the sticky they have for it. otherwise you could check with texas speed they have a car running 9's on the stock bottom.
HEy gUys!

Also honestly if you dont know that you need a stall especially when trying to make the numbers you have setup, you really need a lot more research.
And as far as the best option for over 500 Hp. Well everyones opinion will be different. N20 is cheapest. Turbos most DD able with the stock cubes and with having all the power all the time. Blowers make great power and a little more trouble free than turbo's. NA well. NA gives a little more bragging rights has the (opinion) best feel and safest in most cases.
In the wise words of mclovin "pick up a friggin book or something"
Good luck on the ride sir.
Just go LQ4/LQ9 iron block if 500rwhp your goal n/a. Also a stall is a MUST with any decent cammed motor and a 500 rwhp 346 is not easy or cheap on a 346....As a matter of fact I doubt it will happen even on a well planned a4/na setup...

I apologize, I should have worded that better. I do understand that a stahl is a very important part of any a4 build, and many have said that just doing that a lone will change your car dramatically for the better. However I was looking at making that a mod done later after motor and possibly suspension was done. 
Gas mileage? I hoped keeping the stock verter would help with this for a while until it came to be the only thing holding me back.
Am I going about it the wrong way? I understand that a good verter will allow you to utillize the power that you have and come out of the hole screaming, but I didn't want to just sit and spin.
Thanks everybody! keep it coming!

It ain't cheap, but it's cheaper than a new big shortblock AND the top end you'll need for that anyway.
BTW it's "stall" not "stahl" as in Jerry Stahl. "Stall" refers to the engine rpm at wide open throttle (WOT) with the trans in gear and the rear wheels not turning due to really good brakes or a transbrake.

You can do just 500 (NA of course!) rwhp (on an honest dyno) with a 347 cube completely stock bottom end M6 thru cats and mufflers and still have tons of midrange torque and good drivablility, but you need REALLY, REALLY good heads matched to a (ported) FAST and the right valvetrain. With an A4, rw will be 20-30 or so lower. The cam will be lots smaller than you think.
