IS 800FWHP N/A on pump gas possible with this combo?

Hmmm....this is all alot to think about lol. First off BBC is out of the question. The car is already built around an ls2 and its a very tight squeeze....trying to fit a BBC in it would be impossible at this point without a ton of changes to the car.
I was starting to like the idea of the warhawk, but I am starting to doubt this route now too.
Maybe I should just stick with the current motor I have in it. I failed to mention earlier. Here is the motor that is in it currently.
-Resleeved ls2 block 436ci
-4.165" bore
-4" stroke
-11.5:1 CR
-WWCH ported LS7 heads
-Ported stock ls7 intake
-Huge cam
-Custom Kooks 2" headers with 3.5" race collectors
I was thinking the motor would make around 700fwhp. Car is not 100% finished so I was thinking if I was gonna change motors might as well do it before its finished.
Maybe I would be better off keeping the motor I have and running the all pro heads and a ported fast ls7 intake. Ive seen 20hp gains for a ported fast ls7 over a ported stock ls7. And im sure the all pros would give me a hp boost too??? Would 750fwhp be realistic with a combo like this?

Here's mine...... -Resleeved LS7 block 441ci
-4.125" bore
-4.125" stroke
-11.7:1 CR
-WWCH ported LS7 heads
-Ported stock ls7 intake
-239/261 661/661
-Custom Kooks 2" headers with 3.5" race collectors
Pretty close i would say not?? I really thought it would do the 700 fhp no problem but it just gets tuff once you get up that high. Some people just don't understand......

Here's a link to a thread that was started on YellowBullet as far as the tall deck Warhawk, it mentions the other tall deck blocks out there and is VERY informative and has some well know builders input in there. Check it out.

Just cause they are not LME or HKE, dont mean they dont know a thing about LS series engines. This motor is prolly nothing like yours
They placed 2nd, with a single carb, when everyone else in the top 10 had twin 1150's....
I might even be able to get a snap shot of the dyno sheets. It not only makes badass power for a street motor, it makes down good tq down low also!

Ever consider a dart tall deck SBC , there`s a 461'' small block in my kids nova,using 15 degree brodix heads, lunati 4.25 stroke crank , 6.200 oliver rods,j/e pistons , 14.5 comp. erson roller,jessel shaft mount rockers, and a CV products belt drive , it made 800 h/p, 670 tq , enough to put a 3350 lb car into the 9.40 range. i realize your use is different, but the basic motor would suit what you`re doing, this 461 had a real wide torque range, what you`re looking for

Dude, I have no reason to make anything up. Check it out for yourself. http://www.popularhotrodding.com/eng...ler/index.html

That engine is awesome and it is an LSx but it is not a 50K mile true street engine at all. The valvetrain is much too radical. It would still make great power though with a cam and valvetrain that could live a long time. These EMC engines only have to last several dyno pulls and many can not do that. The EMC stuff is not really comparable to a real street engine besides the fuel.
I am not taking away anything from the EMC which I love or BES as I really respect them and know several guys that work there. They probably could have won with that engine given a little more development time I think.

He said he wanted 800 flywheel. I think it would be pretty easy with the right engine builder, with the right head flow, cam selection etc etc. and I think BES would be a perfect match for the job. and I think it could still be streetable..
This is not a 408, stage 3 heads and a fast 92/92......

I really didnt see anywhere where the OP wanted it to last 50k miles?

Of course BES can build a good engine and they do everyday but a real street engine is not built like an EMC engine. It was built to win a few dyno pull competition and is set up like that which is what I am saying. Anyone can make 800hp with a large engine and great heads and there are many different recipes as well. Not that hard just expensive. That BES engine is for sale for a very good price or was at the Indy show although it might be gone by now. Again the cam would have to be changed or it would be short lived in the real world and that PSI intake can not fit on 99% of cars on this site. It would be sticking way through the hood!
yes the cam would need changed, but I think taking away the RPM range limits, that this motor could make more power by reving it to 7800 or 8k... maybe I am wrong.
I looked into buying this motor, but I just got my 418 finished. So I'll rock that for the time being.

i wish I could afford the PSI intake, I would have one on my junk in a heartbeat!

I have pretty much the exact same setup except ported stock LS7 heads instead of All Pro LS7 heads.
Car makes around 640/600 at the wheels for the time being with KPA readings around 94. I blew up my stock LS7 and used the remaining parts on the ERL 500.
$4000 for All pro heads
$1600 for Jesel Rockers
$3000-5000 for a better intake solution
All those things would probably get your around 700rw on pump gas. But just not feasible for me at the moment with my other money pit. For me, the 10 grand devoted towards a bigger motor instead of adding the abovementioned items to a stock LS7 will make the car go faster. At least I hope so.

Also, I would ask Erik for his exact opinion but the new RHS block is supposed to be pretty sweet. I think MTI made 660rw on their car using the RHS block and a 500ci motor. Car went 200 at the Texas Mile.
