The old "THROW A 502 IN THAT BITCH AND BE DONE WITH IT" does not work if you only have 10K..... Doing a BBC the right way would get into the teens of thousands.....

But again are you looking for 550 fwhp or 550rwhp?? Huge difference and I assume that you have an A4 so you are going to have to have that built and thats about ~$800 for a converter + ~$1500 for a race built tranny so that takes a few thousand $$$ off of your motor build.
With the motor in my sig I have roughly $4000 in the motor including machining, which was $1000 in itself, give or take a few hundred $$$, but I got alot of the parts used except the crank, pistons, timing set, and some misc parts I forgot. Its a good thing to be a member of the forums and have friends that are constantly upgrading their cars. You don't want to know the deal I got on my LE heads and CC306
Just look around the classifieds and buy some parts here and there then you can start the build. But I'd say that if you have the patients (SP) to wait a little while for a good deal then building a 550rwhp motor on a $7K budget is possible.
BTW nice truck man, kinda makes me wish I would have finished mine
I dig the LT1 truck
these guys are on the ball, 550 @ the wheels ain't gonna be easy w/o a power adder, but I'm sure it's not impossible
I'm very curious about the combo mentioned by ProPorts1
my 396 doesn't make 550 rwhp, but I'd sure like to get it there lol (guess that white bottle makes up for it though)
I am curious what RWhp guys like Ed Wright are making, even -Pepe- and some of the other guys with BIG solid rollers

With my solid roller stroker, there was a lot of money in machining and labor. If you can do some of this yourself then your budget will be more effective. It's not just the engine that will cost you, it's the other supporting mods "necessities" that will add up. And dont' forget, once the engine is completed, there is the matter of everything else on the car being able to support that power.

One last thing, as with any good engine tuner, they need something to work with. Even a great tuner like Ed Wright can only work so much magic if he's tuning low performance motor. I didn't spare any expense with mine so this wouldn't apply to me.

My ears are growing as we speak.....please do tell. All Pro heads? The heads just shot his budget right in the ***.
550 RWHP through an auto all motor is one TALLLLLL order, VERY tall.
That is about 680(ish) to the flywheel. You can do this on pumpgas? Because race fuel is $8 a gallon.
I am trying to get CLOSE to the 500 rwhp mark through an auto...and dude I spent some CASH, $7000 aint gonna do it, I gaurantee that.

Verdad Gallardo Ed with a stock converter in his car WAS making around 510 to the wheels with stock ecm, but you cannot use his car as a barometer...Ed has split hairs with that engine combo, tried everything under the sun on the dyno. Things that 98% of people just cannot do. He has a FAST system on the car now and has since run in the 9's with it.

Come to think of it, getting 500 rwhp out of an NA LTx through an M6 is a real rarity.
I'm thinking 414 cid, raised runner (at a minimum) or 18 deg heads, SP intake, 13/1+ compression. . . That'll be a smooth $25k for the engine alone.

Tony shepherd made in the 530's at the wheels with a th400 and a 9" rearend..... that's naturally aspirated..... but there is way more than 7 or 10K in that motor.... I got alot of my ideas from him which is why our motors are very similar.... I'm expecting about 525RWHP roughly from mine.... Our engines are similar but we're trying some things that Tony isn't as well and I don't claim to have "ALL" his secrets..
It is possible but either of these motors (and I'm sure Ed Wright's as well) have closer to 20K in them.... I have like 12K just in parts last time I checked.... without ANY machine work.... Power and money go hand in hand. You want more you pay more....

383, 11/1, AFR210 Race Readies, hydraulic roller cam in the upper 230's on the intake, ported LT4 intake.
A larger solid roller cam will reduce the need for the extra cubes, compression, and big heads.

Since you decided on the AI 200cc heads call them and see what they recommend.

I know a couple of guys that run Harold's heads and they're very satisfied. In my book he's one of the good guys.
With the response Harold's posting received I wonder how long he'll continue to sponsor this website.

I can tell you Harold at PortPros does have a combo that will make that power. My car is a prime example for one and it was even setup for nitrous. If we would have gone for just n/a my numbers would be much higher. Just look at Harold's credentials and background from where he learned his trade. He is one important asset to this site and the racing community.
I will tell you it is not cheap to make this much power n/a.
Guys it is not impossible to make that power. Joe O has been doing it for many years with his combo. Just depends on how much money you want to spend.

Ramen Noodles are your friend with this hobby...TRUE STORY
If I break 520rwhp N/A soon with the dynotune I'll be excited. I broke even at 500rwhp N/A last Sep and with the new cam I humbly want 520, if she does better that'll be great.

out of curiosity did you ever call Port Pros?
tony: saw a dyno vid of your car, wicked.
-Pepe-: keep us posted on that #
in the end I totally agree with aboatguy, torque
call port pros and anyone else and get their input and combos and compare cost
just be sure to be honest about what you want out of your truck so they can recommend what will make you most happy with your ride
good luck
