high comp solid lifter 403ci okay guys i have left the hydraulic 5.7 world and am completely lost. to start off i can list the parts i would like to run but the goal is 620-650rwhp and 565-580 rwtq on motor and then nitrous to get over the 800 mark.
6.0 ls2 block
compstar 4.00 crank
compstar 6.100 H-rods
mahle 4.005 (13-14 to 1 compression) nitrous pistons
AFR 225 or TFS 235 heads ported by mamo
victor jr ported by mamo
sheet metal elbow and NW 90mm tb
kooks or qtp 1.7/8 or kook 2" headers
custom solid roller cam (thinking 25X/25X .7XX/.7XX on a 109LSA)
lifters?
car will run on leaded race gas at all times (probably c12-c16)
what clutch do you recommend also?
to top it off, it will get a 2 stage nitrous setup.
first stage will engage at launch through 4th gear 100 shot (looking for a 1.3-1.35 sixty foot)
second stage will engage in second through 4th gear 150-200 shot (looking for 145-150 trap speed)
let me know if i am on the right track, if there is an easier way, or do i need to change things?

We're building something similar for a customer right now, but we're going with 11.3:1 for as street car. We use a Wiseco piston and hell fire rings for nitrous. We're also using an iron block instead. Your on the right track with the Callies, that's our first choice as well. Obviously the power is going to be made in the head and cam choice.

the car weighs 3520 with me in it andi would like to drop about 100 pounds, gears are 4.11 but i think i am going to change them to 3.90, and tire is 27x10.6 but if i leave the gear alone i might step up to a 28.
I would think that the 25x/25x cam would be a little on the small side for a solid roller cam. I think that you would be better off with a 264/272 @.050 duration, 111*+4*, and .731"/.731" lift w/1.7 rockers.

hey i love big cams but i want it to work well with nitrous too. i will more than likely have patrick g spec me a cam. the cam above sounds good to me as long as it runs good.
also, the exhaust is a custom 4 inch y pipe with 3 inch primary tubing and 4 inch all the way back to a delta flow race muffler. if i need a cutout i can have my guy build one.

With that much compression and nitrous you need to start off with a Katech resleeved block with billet caps and ARP studs. The first problem you are going to have is lifting the heads. I suggest stepping up to 1/2" head studs, ARP 2000 series or their exotic L19 series. Finish it off with Cometic MLS head gaskets. Use a LPE nitrous retard (4-6*) and keep the AFR down to 11.5 to 12.0 when spraying. Also use a plug colder than the TR6 when at the track.

well the block i already have so i am going to use it, my tuner is very good and i trust him. weber racing said that the ls2 block is good enough for the goals i have and i do not have the money for a race block or i would build a 454 lsx engine. it will get the 1/2 studs and billet main cams with girdle. i figure it will take awhile to do it right.
Well I am building the same thing.
aluminum 402
Lunati crank
diamond pistons
eagle rods
1.7 T&D shaft mount rockers
L92 heads
262/268 solid cam
and as of right now a gmpp intake with becks elbow
I am shooting for 600/650 on motor to the tire but the compression will stay around 11.5 to 1.

But when you add a 150-200 shot, you're going to want to open the exhaust valve 6-8 degrees earlier (compared to what worked best NA) to reduce your pumping losses (while keeping IVO,IVC, EVC and overlap the same). The net result seen will look like you're adding advance to the intake centerline, widening the LSA and increasing the exhaust duration, but in reality, all you did was open the exhaust valve 6-8 degrees earlier while leaving the other valve events alone.

How do you know what LSA you want to use when you don't even know the duration??
Also I believe you would be better off using a 4 bbl type of TB rather than the elbow.
3rd. If you by chance make that much HP, you will never make that much rwtq out of a 40x cube motor.
Good luck.

well as far as the intake setup, i might get a 1000cfm tb and would like a sheet metal and will probably end up have one built anyways. the lsa was a guess because patrick g will end up speccing my cam for me and what he says goes in my car.
weber racing said that if i build a setup like this, the motor should do 650 rwhp, torques will come with nitrous.
thanks for everyones .02, i actually like to have people on both sides of the fence so that i can make a good decision.
