Posted 22 February 2008 - 10:40 PM

Well, I have started a new project and I thought I would share / document the build in this thread. I am keeping alot from my old set-up (exhaust, fuel system etc.). I always wanted a nasty N/A stroker from day one however never had the chance to build the one that I wanted...until now. I will make an index of this thread in this post and update what post number each phase of the build starts. I am planning on having the motor installed and running in May with tuning all summer.

O.K. first off the motor. I have been researching parts for years for this build and this is what I chose to do. Some may disagree with my choices and that is fine, as I had a hard time debating on if I wanted a low revving torque monster or a high revving HP monster. Naturally the L92/l76 combo was debated for the low revver as well as about a dozen head/cam and intake combos for the high revver. Here is what I settled on:


SHORT BLOCK:

-6.0L Cast iron Block (LSx block was overkill)
-Eagle forged LS1 4.00 Stroker Crank
-Eagle LS1 6.125 H-Beam Connecting Rod Set with upgraded ARP 2K rod bolts
-Diamond Racing Forged Pistons (4.010 Bore, 4.000 Stroke, 6.125 Rod length, 1.120 CD, Flat Top with -4cc Valve Reliefs, 0.927 x 2.50 Wrist Pins) *Obviously a 4.030 is in the table depending on machining issues, minimum of a 402 and a max of a 410*
-TSP Total Seal Ring Set (4.010" + 0.005", 1.5mm AP Stainless Top, 1.5mm Napier 2nd, 3mm oil
-Cam bearing set for LS2 Block
-Clevite LS1 H-rod bearing set (for stroker applications)
-Clevite LS1 Main bearing
-ARP Main Stud kit for LS1/LS6
-GM LS1 oil restrictor
-GM LS1 Oil Galley Core Plug
-GM LS1 Large Coolant Plug
-GM Engine Block small coolant plug (LSx - based engines)
-All the block work including Vat Block, Line Bore, Bore/Hone w/ TQ plate, precision balance rotating assembly, line hone...

LONG BLOCK

-Precision Race Components Stage 3 ported and polished LS6 Cylinder Heads (243 castings): 2.08/1.60 stainless steel valves, dual valve spring kit (good for .640 lift) with Titanium retainers, 64cc Combustion Chamber
-TSP cam 248/254, .615"/.622", 113 LSA
-Yella Terra Ultra Lite series non-adjustable 1.7:1 roller rocker arm set
-TSP Chromemoly 7.40 pushrods
-GM LS7 Lifter kit
-Rollmaster double-roller LS1/LS6 Timing Set - standard bearing
-GM 6.0L MLS gasket
-ARP LS6 cylinder head stud kit (12 point) (remember this is a nitrous motor)
-GM LS1 Lifter Trays and associated bolt
-GM cam retainer plate and associated bolt
-ARP LS6 camshaft bolt kit
-GM LS1/LS2 rear main seal housing gasket
-GM LS1/LS2 Timing cover set
-GM oil pump O-ring (LS6)
-ARP balancer pulley bolt
-GM LS1 exhaust gasket
-GM Oil pan gasket
-GM water pump gaskets
-GM LSx rear main seal
-GM LS1 front crank seal
-GM engine block dowel pin set
-TSP ported and shimmed LS6 oil pump
-Front coolant pipe for LS6 Intake manifold
-Rear coolant plugs for LS6 Intake manifold
-GM LS1 timing cover
-LS1 rear cover
-GM bolts for the valley cover, timing cover and rear cover (31 total)
-F.A.S.T. 92mm TB LSx composite intake manifold (ported)
-LS2 throttlebody (05+ vette style)
-X link adaptor
-F.A.S.T. fuel rails
-F.A.S.T. 38# injectors (flow rates rated for 42psi, at 62 they flow ~45#s, I also have the green tops ~50#s)
-GM windage tray, 99+ trucks, with nuts
-99-06 GM truck pan kit
-GM oil pick-up tube 99+ truck
-GM LS6 valley cover (upgrade from the stock truck cover...planned for my crankcase venting system)
-TCI SFI-Approved Flex Plate with LS1 bolt pattern (spacer for 80E conversion)
-Powerbond Truck Underdrive Pulley (keyed and powdercoated)
-Aeromotive boost/vac referenced FPR
-Mezeire Electric Waterpump (anodized red)
-Area51 idler relaction bracket
-Custom CAI (by me)
*11.5:1 static compression ratio, shooting for over 600+ HP Crank HP N/A with a power curve peaking at 6400-6500RPMs*


NITROUS

-Nitrous Outlet custom direct port nitrous system
-Progressive controller, with window switches and purges (Trick performance P-gauge)
-Dedicated fuel system (pump, regulator, lines, fuel cell)
-Twin 10# bottles (may do a nitrogen assisted system, haven't settled yet)
-Jets to deliver 300RWHP shot progressively controlled with window switch, can go to 400 if desired and down to 100. This is RWHP ratings :smash:
-all of the goodies that go along with a nitrous kit to make it safe and legal to run
-custom intake painting and direct port line routing (that is where the "Project Black Widow" comes in.) :thumbs:

TRANSMISSION (and extras)

-Going to freshen up the Finish Line Transmissions 65E and add some new parts such as a billet INPUT shaft and all soft parts. I have most of the parts for the 80E conversion however I want to see just how far I can push the 65E. With progressively controlling the nitrous and having a window switch for the shifts, this tranny just may hold together for a nice 1/4 mile run. Regardless, the 80E is inevitable so I started that project in the background.
-Precision Industries Vig 3400 stall tripple disk lock up 10.5" converter
-Forged driveshaft yolk
-Rebuilt T-case
-Detroit locker
-Driveshaft loops
-New AS&M headers (Belenger now due to issues dealing with Arizona Speed and marine!), hollow cats

Looking forward to breaking some parts along the way! :lol: I will be doing all of the installs and tuning in my garage. Let the fun Begin!

very nice sounding build. i too agree that a stock iron block can be built to handle a lot of abuse and it sounds like your moving on to a nice setup.
.
and imo nothing beats the sound of a meaty cammed na stroker motor. :cheers:
