69trk · 12-26-2013, 02:50 PM

Hi, Not is a custom made, the truck manifold work good , but because of my setup need ones can flow more highter, so it are very easy to do we build that from black steel elbows and reducer from a boiler supplier.

Hi, The bracket come from lsbracket.com this is a high mount bracket kit. the alternator and power steering come from 2002 chevy silverado 5.3Lt.

Very cool, and way different than all the custom sandrails and audio competition cars I see come out of Puerto.

BR3W CITY · 12-27-2013, 12:57 PM

I'm not used to seeing the GV units behind the already-overdrive trannies, do you really get much use out of some of those doubled gears? (without being able to ECM/TCM control the gv unit)

In my case it works very nice on highway and the overdrive + Gv Overdrive + LU cause to drop around 1000 rpm on normal or cruise driving not race, when i switch to manual mode i will able to control the gear vendor through from mastershift paddler shifter control system.

Damn, after looking at your build (and watching like 2 hours of Travel Channel), makes me want to go to Puerto Rico lol.

Have you used the Mastershift unit before? I read about it and another similar system, but I've never seen it used, since most of the guys with 6spd auto's will run the GM TuTd shifters. Does it allow for "full" control, or just the GV? (getting tap-shift for all 8 speeds would be epic)

i Have an Transgo HD2 modified valve bodies so when it put in D4 and switch to auto mode the tranny shift like factories does 4 + manual activation GV Overdrive , But when i ****ch to manual mode i have totally control over the tranny and GEAR VENDOR so there's when the master shift come on, the mastershift you can program it to gear splitting with the GV you will have 8 forward shift from your paddle shifter.
i have an another Modification in this tranny to handle the power from LSX 427 turbo.

1-Hardened Input Shaft
1-Hardened Hub.
1-TCI 2.97 First Gear Set
1-Intermediate Hardened Shaft
1-Alumum Direct clutch Assy.
1-Pump modification
1-34 elements Sprags
1-John Winter 3400 Stall 3 Clutch Lock Up Converter
1-red Alto Frictions
1-kolene friction plates
with this mods the tranny hold over 1400++ with out any issues

Looks like you kept the coil packs on the valve covers... Did you just custom make some plug wires andgo around the manifolds?

**Dieselwrencher** · 12-27-2013, 05:51 PM

Very cool build and nicely done! I really like the aluminum piping and is that the intercooler on the LH fender well area?

Wasted Income · 01-02-2014, 11:12 AM

Nice setup.

13xx hp at the wheels? Damn. I need an LSx block and some 6 bolt heads...

Naw ya don't. Just the heads....and if you REALLY wanted to I may know someone that has a very nice friend at MAST that can track down their 6bolt heads. I feel you don't need a new block till you blow on a hole in the one you got....and with an gmpp LSX block, you'll blow a hole in the block sooner than you'd like heheh.

I'd be curious how you'd propose bolting a set of 6-bolt heads on an LQ4?

Unless you're talking about a Bill Mitchell or a Warhawk block...in which case I'd still rather have the LSx for less than half the price

There're few ls block manufacturers that they make 6 bolts heads compatible.

GMPP
RHS
Warhakk, but need to buy the head to then, because of bolt pattern is different from GMPP LSX.
