Decided to let out some of the things I have been rounding up these days and in turn try to gain some new info needed to finish this build up of sorts...

So here goes.

LSX #416 from my local dealer.
4.125 bore
4.00 stroke callies 24x crank
6.125 callies comp H-Beam rods
-5 cc 2618 Manley coated pistons
Hell Fire 1/16 1/16 3/16 nitrous rings
N-Motion single row T/Chain
Lingenfelter H/V Oil pump
227/240 639/649 on 114
L92 CNC'D 2.18 1.60 73cc heads (WCCH)Flow #'s Soon to be released.
Harland Sharp 1.7 Roller Rockers
arp ls2 head studs
L92 truck intake w/90mm DBW T/Body(For Now!)(Awaiting TVS)
60lb EV6 Injectors w/E-85 capability(For Now!)
1 3/4 Long tube headers
2600 triple disc Stall(?????)

Thats hitting the big stuff so far.Machine work is a joint effort from both very reputable and affordable sponsors from this site.(TPIS)(WCCH)(MAGNACHARGER)Parts gathered are also mostly procurred from sponsors(SDPC) and members from this site.
This build up will be flywheel dyno'd and hopefully turn out some really nice Numbers.
This is where the help comes in.
1. 6050lb total weight DD Suburban.It currently has a 5.3 maggie equip'd 4l65 Built tranny.will the 2600 stall be enough?Should I go larger and if so How much larger.
2. Constanly Bothering the guys over at Magnasun for the Soon to Be released TVS L92 Based Blower.Did my Cam choice Go too far? It is Really hard to try to create a NA/FI cam grind W/little draw backs from one to the other.(WCCH)Heads will take the Flow.
3.Total compression is falling in at 11.1 to 1 So 6 psi will probably be the max.Am i Going to far?(Vortec's are pushing 5-6 psi on the ls7 vettes @ the same compression ratio).
4. Gears Upgraded,Currently they are the stockers but would like to go to 3.73-4.10's with new lockers.Hopeing to help move this weight around a little easier.
5. Headers?Should i Go Full Custom and Supersize them to 1 7/8 step 2" and
3" dual exhaust out?.

And the last one How Much HP NA/FI with TVS2300 do you THink this COULD produce.Idle Quality,And Did I just take the DD out of my fun family go getter.

is that gonna be a stepped header(1 3/4-1 7/8) or straight 1 3/4?

headers might be restrictive. might wanna sell them and step up to a 1 7/8 header. good luck with the build

Still in R&D working with Jr @HS and Richard over @ WCCH They are working together to make them a nice fit.

Good thing wal-mart sells gas up here.

You know how much was milled off the deck? Was it brought down to 9.24 from the LSX 9.26?

BTW, nice setup you got brewing there.

I believe we brought down to zero deck so 9.24.

Thanks!
