Pretty much as the title states. The goal is 680-700ish whp. I'll be retaining quite a few parts from my last set up. Which is:

-Precision 775hp intercooler. Precision 1200's.
-BWs366
-Nori-bilt turbo mani.
-VictorX intake mani.
-Oem gsr trans/quaife lsd.
-Walbro 400, Aeromotive a1000 regulator, -6 feed and return. Idk if I'll have enough pump, but I'm gonna use it and see what it makes. I'll upgrade after if needed.

Currently how the suspension sits:

-Nori-bilt traction bars.
-HardRace front camber kit, Hard race front lower control arm bushings,HardRace compliance bushings.
-PIC trailing arm bushings, PIC lca's.
-Not sure if I want to purchase PIC or Skunk2 drag coilovers.

As far as the new set up goes:

Block
-CSS Ls block
-Crower I-beams/JE pistons.
ACL bearings. Unsure what clearances to use.
-ARP main studs. Not sure if these will be necessary. I figured it wouldnt be a bad idea considering the hp goal and rpm the rotating assembly will see.
-ATI damper. Again not sure if I will need the street or race version. Im not sure if thats horsepower dependant.
-Competition twin disk.

Head:
-T1 spec Webb cams.
-Ferrea or Skunk2 Pro valves and valvetrain. The Webbs I bought came out of one of SpeedFactorys drag cars, they said they were using off the shelf Ferrea components. I also called T1 and they recommended Ferrea aswell. I might end up going that route.

Ignition:
Summitt Racing digital ignition box.
Turbols ignitor bypass.

I might have left a few things out. As you can see I'm still uncertain on a few things, but I'm sure I'll get great advice and help on here. I'll post pics as soon as I get back in town from work.

 

i wouldnt try to run 700hp on a CSS stock sleeved block lol dont cheap out, get sleeves. VictorX manifold is kinda undersized i think at the 700hp level, you probably should look at a GE manifold by that point. I also cant argue against the ARP main studs, that should be a given, just make sure the block gets line honed.

 

Looks promising

 

I Would go with a sleeved block myself, for a couple of reasons 1 you can run a bigger bore, and have the room for more in the future, Other Then that Good Stuff man cant wait to see old yeller back out & maybe you can get the 10 your looking for

 

CSS is good just make sure it's tuned well.
Need more pump
Injectors? More
Good luck with the build.
Not to jack the thread I'm going for about the same power with my CSS block. Running a custom s362 vgtish thing.

 

We run dual 044s and make 700+ on one of our cars

 

I feel confident with the fuel system. I'm gonna say the weakest part of my build is the stock transmission. My friend made 690whp with the exact same fuel system as I have also with q16. The only difference really between our set ups was hes using pro 1's and a 72mm turbo. The VictorX is an old man, but a beast. Just about everyone back in the day making 800+ hp was using a VictorX. Not trying to base my results off of similarities of other set ups, but even if I come up short a few dozen hp of my goal, I'll still be happy.

 

Those CSS blocks hold a lot more power then people think. Good luck with the build, car should fly.

 

I co-sign going sleeved but Shawn is set on the CSS block. If thats not the E85 compatable walbro 400 be sure to upgrade buddy. Some ID2000's would hit the spot as well. at 600hp im at 60-62% duty on the injectors I believe. It MIGHT be just enough injector to hit 750whp but not on a mustang dyno more like real time numbers so expect to run out of fuel around 680 on Nori's dyno which should put you close to your goal

If you need any help with it LMK

 

You are absolutely right, they do hold a TON of a power...I still wouldnt trust stock sleeves at 700whp. I think everyone is missing the fact that if you have 700whp, you probably have over 800 at the crank.

 

Thanks buddy.

 

Rich777 can tell you what your clearences should be. I know they should be green but I forget the exact clearances of green.

 

The only issue I see with the CSS system is that the middle of the sleeve has no support and is basically stock.., there's the weak link... 800hp worth of cylinder pressure will find a weak spot in no time. While the CSS is basically a fancy block guard, it works... however at major league power levels I would do a traditional sleeving on the motor, cheap insurance if you look at the build as a whole.

 

Last heard css hasn't had a cracked sleeve yet.

 

Im gonna run 600hp on mine

 

Im pretty sure they have and its when you start pushing past 700hp. Just because 1 guy is running 9's with it doesnt make it a perfect system. IMO why spend 700 dollars by the time your done on a css and if you crack a sleeve the block is junk when you can spend another 400 and have a bullet proof block from benson Just sayin

 

Well you never know, I may change my mind. I'm still a few weeks away from buying a block. Either way, I look at it as how much power the blocks are handling as opposed to ET's achieved. If I end up running a CSS and it fails well then we'll know wheres its limit is at lol. A thought that ran through my mind is if something catastrophic happened in the cylinder and snagged the wall deep enough beyond a honing fix then I'd be screwed out of $1,XXX. Perhaps I'm putting too much thought into it.

 

gay, h-t isnt allowing me to post pics right now

 

not as likely on a ductile iron sleeve like a Golden Eagle. but I see your point.

 

700 is doable on stock sleeves. jeff evans ran a stock sleeved c5 block daily drivin few yrs . no issues

 

The weakest part of the build I think will be the stock transmission. I remember seeing someone on here saying they cryo treated their oem gears. Anyone know if thats effective?

 

He didn't run it that power all day every day as though he was at a dragstrip. Just because it dynos 700whp, doesn't mean he's running it at that boost pressure all the time. If one has at minimum the CSS, sure, but that's not a very accurate and direct correlation

 

turbo LS- the css is 300 not 700... so its a saving of roughly 700. Unless i missed what u meant.

 

375 plus decking and boring

 

beat me too it GPR thank you sir
