Ron, you don't need to gett he LS6 heads reworked-they'll be fine out of the box, If you LS2 block you will hae a 364 but you will have to relocate your cam position sensor and knock sensors-Dave sells the harnesses for that. You can sell your P1SC unit outright or send it to procharger to get upgraded. You still keep Andy's bracket-you can go down to a 3.85 pulley on the D1 and it with the 6 rib you should be okay. If you want to go 8 rib you will need different spacers and shims for your current bracket-Andy can set you up with those. You can purchase the 8 rib pulley setup from ATI for around $900. FWIW when i made 650 rwhp-the car's AFR was 10.1, we only revved it to 6400 and i used a 4.10 pulley on a 6 rib and saw 11psi-that's why i say 700 will be a breeze.
Ron-sorry forgot to answer a some of your questions-your stock heads will be fine for 700 rwhp-if you want to spend some money but not too much just get a set of LS6 heads and as far as intake a LS6 intak is all you need. And as far as cubes go-just get the 347-the bigger you go the more torque you make and the more you will break driveline parts.
I agree with this, (I know, who cares?)
As far as the Driveline parts go, you can save them by running street tires which release the torque for more useful things like melting the tires.
I just went through this exercise and decided that more cubes means less pressure in the intake manifold for the same power. Since Dave had a 6.125 callies crank in stock and an LS6 block, I grabbed it for myself.
This is a very expensive way to get only 30HP but it is more power with less pressure which I think is a key consideration.
LS2 is a better and bigger bore block. It is also cheaper than an LS6 block to buy. After 2002 all the blocks became LS6, GM stopped casting the LS1 block.
That's all? Steve ( PeterPan) made over 740 with just a 347 and 317 heads-D1SC and the same boost-I like the 347
The 347 vs 364 are almost identical expect for bore size. I believe peter made more peak power because he was using a large cam vs my stock 02 z06 cam. In most cases the peak power does not lead to a faster ET, but may perhaps give you a little extra MPH. I took my whip and smashed off 3 back to back low ten second passes. I am very happy with my power under the curve.
By the way guys...thanks for your input...for us non engine builders its nice to have some idea whats goin on in the LSX world before purchasing one....I like to get the best bang for a buck.

The LS2 is my favorite and does make a little more power. The bigger 4.00" bore allows the heads to breathe better since they are unshrouded alot more. This is good way to help out the exhaust flow in a boost setup. Its easy to get it in, but you gotta get it out. Go with the LS2.
I'm on the fence as to go big cubes and nitrous or small cubes with an upgrade on my s/c. As for Hp, I'm looking in the upper 600rwhp range.
I'd like to do a A4 conversion at the same time.
Right now I'm leaning to the big cubes and nitrous....
With the money you will spend on a tranny/converter ($2000 for the tranny and $1000 for the converter alone, plus extra parts and pieces), the forged engine ($2500-5000 depending on size and parts). and the nitrous (minimum $1200 done right) or upgrading a supercharger, you might just want to sell your car and get one that is allready done for $30K or so. Start browsing the FS section....just a thought.
But the L92 heads lack in the exhaust flow , not good for blower setups IMO. I'd rather see a Patriot stg 2/3 head for $1300 then a stock L92 for $1100.

True...but you don't know what your getting...maybe someone elses problems too.
My wife said to me that I should just buy a new Z06...I almost hit the floor....
I think that statement could be true to over 90% of us who is hooked on SPEED....and not the one in the needle.
A 427N/A engine with a RPM A4 conversion would look nice

Then get a set of CNC L92 heads. Of course, there was no mention of a budget, so why not plan a build for the Warhawk block and heads.
The thing is with big cubes, the motor will make the same power with less boost (less cylinder pressure), which is less detonation prone. And you have the option if you want more power, then just run the boost where you was planning on running with the small motor. Someone said Torque breaks driveline parts. Well, Torque is what moves the car. Traction is what breaks driveline parts. You can put a set of slick on a stock Z06 and break driveline parts if you rev it up up and side step the clutch pedal.

100% No need for a big cubed LS series motor when a forged 346/7 cid motor like EB02Z06 just built or Peter Pans (another great example) will make all the power you will ever need (and then some) and will allow you to hook up a little better with you 60 ft times (your launch) if you plan on hitting the 1/4 mile (vs. the instanst HUGE torque hit associated with a stroker or KENNE BELL S. CHarger, etc., etc.)!!
Great video man and that car is bad azz! Who's drag machine is that (ROY's I assume) or are you the proud owner? The sound track in the first video also kicks azz along with those LS7 heads with that 10.2 N/A run!

Thanks! That's Don's (FSUW) C5... Roy's car should do the same thing this season... I had a simmilar motor in my Firebird but sold it to a guy with a C5

So Andre....if I go the 427 route what drivetrain parts should I replace during the install...I know that there is always a weak part even when you replace out the old parts to new parts.

The dreaded 6 speed....yes I would replace it with a A4 conversion. I guess its easier on driveline parts.
Would a A4 conversion pay for itself in the long run?
Ron
If you goto the track often, then yes the A4 will pay for it self in the long run, but if its 95% street use, you won't get the traction to break parts in the M6
