Post your forged 347 builds here...
Post your forged 347 build parts & dyno/track numbers... Looking to see what other people have done with their forged 347 builds. I'll start:
Shortblock:
'01 LS1 block, cylinder & line honed, deburred oil return areas.
Stock crank, polished/balanced
Diamond Racing -8.6cc dished pistons w/valve reliefs (Diamond 11503)
Pistons coated with heat rejection coating on top, anti-wear coating on sides
Total Seal piston rings (included w/pistons)
Lunati Pro Mod forged steel 6.125" connecting rods (Lunati LAE-1)
Clevite S & P bearings for crank/rods/camshaft
ARP main studs
ARP head studs
COMP custom cam 218/230 .605/.605 115+2 XFI lobes
LS7 lifters
Top end:
Stock GM 241 cylinder heads milled 0.045"
0.051" compressed thickness MLS headgasket
Patriot .660" lift dual valve springs
COMP rocker arm trunnion upgrade for stock rocker arms
COMP hardened chromeoly pushrods
LS6 PCV system
Intake:
LS6 intake manifold
Ported/polished throttle body
SLP Smooth Bellows
Polished/descreened MAF
SLP Blackwing lid
98+ WS6 lower air box
No power numbers, as I haven't thrown a blower on it yet or gotten it dynotuned.

Your build pretty much matches what I'm up to. So far I'm still in the parts accumulation stage for my CTS-V
LS6 block
Diamond -8.6cc pistons
Compstar rods
LS9 head gaskets
Stock heads cleaned up, patriot gold springs
LS6 cam
ARP studs
On3 76mm .96 turbo going in the rear, probably pushing 15-18lbs when I'm done.
I'm also looking for what people have made on similar setups.

im curious to see what steam vent setups people are using, or if they are even using them. i plan on running one, and adding ls6 valley covers just for insurance, and to keep the temps down on those pesky ringlands. its very interesting after you have read about it some.

well, so far i have bought everything for the bottom end, including the junkyard 5.3. pistons and rods,heads, everything i bought came from this forums classifieds lol minus the camshaft and intake and a few odd n ends.
My shortblock cost me:
5.3 engine-500$
wiseco forged Pistons-350$
oliver billet steel rods- 450$ (one rod was .10 out of round, it got to hot, had to get a replacement rod)
Replacement rod^^ 150$
take that right there, 1450$, i dont think thats too bad really, for a tough *** bottom end!
So far, ive spent 5800$ over the course of one year, which isnt bad i dont think! Including 90% of my engine parts, and transmission stuff, and actual vehicle parts.

Shortblock
'98 block cylinder and line honed
Stock main bolts
Stock crank out of a 2002 LS1 (spun the crap out of mine)
Diamond -9.6cc pistons
Scat I-Beam rods with ARP 2000 bolts
Clevite main and rod bearings
Total seal rings
LS7 lifters
Melling oil pump
LS2 timing chain
Valvetrain
PAC springs
TSP hardened pushrods
241 heads
COMP trunion upgrade
PCV system delete (running 2 lines from covers to catch can, and a check valved line from can to exhaust for vacuum)
Stock GM MLS head gaskets
Turbo is going on right now. Broke the motor in for about 1600 miles this past summer and it is running well. The drop in compression hurt the power a little bit, but 12 PSI should make up for that

Haha. I'm just worried once I get it on the dyno it will disappointed. Shop told me they will only use methanol/water injection as a cooler (idk of that's going to affect my goal) and right now 50/50 on a set of 317 heads I have or buying Prc 225cc heads..
Come on guys get in here and give some numbers. Hp/psi/et... any and all
