Re: Another way to skin the cat; the High Torque 292 LS swap
Looks great. Did you do anything to the motor or is it stock? I am putting a 4.8 in my sons truck. I did put a cam and valves springs.

Very awesome build and swap! Great fab work!

Re: Another way to skin the cat; the High Torque 292 LS swap
Thanks for the compliments.
Quote:
Using the stock injectors meant modifying the Holley fuel rail brackets (I think I put some pics of the brackets on the first page of this thread), but there were three reasons for the choice as I had LS1 injectors on hand. 1) The tune didn't have to be modified for different injectors. 2) The stock injectors were black. Seriously, the name of the game here is to make the engine look correct for the time period. The LS1 injectors are gray and I thought they'd stand out more than the black ones ![]() 3) The truck injectors are shorter than the car injectors which keeps the rail low enough that the DBW electrical connector cleared the rail. Had I used the LS1 injectors, it would have been impossible to plug in the throttle body. It's completely stock. My tuner is the one who convinced me to go ahead and try running the MAF directly on the throttle body. He said it would work fine with the stock components (and it did). He mentioned in passing that it would likely be problematic if I went to an aggressive cam. I'm not sure why, but I only assumed that a lopey cam would fool with the intake air enough that the MAF readings would be inconsistent given its location. |

Update
I've put just over 600 miles on the 4.8 swap so far. Or at least I think I have since my odometer quit working at about 400 miles
![]() Today I had a chance to fix a couple of minor annoyances. First, the fresh air side of the PCV hose (in the passenger's valve cover) was just unsightly to me. There were enough unknowns when I built this that I didn't know exactly how I wanted to handle the PCV system. I had initially planned on running an air cleaner with a snorkel, and the present PCV location would have been perfect with a very short hose. Second, is that the same PCV hole in the valve cover doubles as my oil fill. The problem is that there is a sheet metal baffle inside that makes pouring in 6 quarts of oil rather "fun". So, without further delay, I started with this: ![]() This is a good photo of the valve cover adapter while the cover was off: ![]() It didn't take much to grind the baffle loose: ![]() Then I drilled the end of the valve cover and installed an AN6 90* bulkhead. Note that no baffle is needed because this is the inlet side of the PCV system where air is entering the engine. So, there is no concern about oil being sucked out of this hole: ![]() On the inside, you can see the sealing washer and also that I cross drilled the nut and fitting for a cotter pin so the nut would never back off inside the valve cover: ![]() I used a 3/8 JIC swivel hose end in the PCV hose as it will thread onto the bulkhead: ![]() And, finally, here it is all buttoned back up. The PCV hose now goes unnoticed and the oil filler actually works! ![]() |

Re: Power Steering and Plug Wires
The pump has a 16 mm male o-ring fitting which is 16mm x 1.5 thread. The steering box has a 3/8 inverted flare return line (5/8 x 18 threads on the nut) and a 7/16 inverted flare pressure fitting (11/16 x 18 threads on the nut). The hose that I had made at the Parker hose store just has male 3/8 JIC connections on it (which is the same as -6 AN). The hard line is connected to the hose with 3/8 tube nuts and sleeves.

Re: Another way to skin the cat; the High Torque 292 LS swap
That is the BEST looking "292" I have seen
Can I get a close up of the coil location brackets installed?

Re: Another way to skin the cat; the High Torque 292 LS swap
Nice way to "skin that cat"
Beetle..on the steam ports my engine guy said I didn't need them so I cut off all the tubing and welded up the banjo ends and bolted em back to the heads.if you look at his post #11 in the last pic you can see the tube going across the front of the intake and into the water pump.my 6.0 didn't plumb into the pump it went to the radiator and not having a fitting there I chose to block it off. |

Re: Another way to skin the cat; the High Torque 292 LS swap
Thanks, got it
You have WAY more clearance than we have in that location, but I do like your idea (Many) of grouping 4 together Did you machine the valve cover adapters or are they a product of the later sbc center bolt adapters?

Re: Another way to skin the cat; the High Torque 292 LS swap
The valve cover adapters are from a company called ICT Billet. I bought them on eBay and they seem to work well (no leaks so far). They are purpose built to put SBC valve covers on an LS head. They have an o-ring grove machined in the bottom to accept the factory LS valve cover gasket. My only complaint is that they didn't come with any hardware.

Re: Another way to skin the cat; the High Torque 292 LS swap
Killer motor man !!
How tall is this setup compared to the truck intake and cover? Like to the top of mass air? |

Re: Another way to skin the cat; the High Torque 292 LS swap
Thanks! From the top of the valley cover to the top of my air cleaner is 13-1/4 inches. The 4.8 in my 2012 Silverado measures 12-1/2 from the top of the valley cover to the top of the engine cover. So, my setup is slightly taller than stock, but it would be possible to make a shorter air cleaner if you need that extra 3/4".

Re: Another way to skin the cat; the High Torque 292 LS swap
[QUOTE=dayj1;7147162]
I've had this taking up room in my shop for the last year or so waiting on the right vehicle to come along for a swap: ![]() It's the "littlest" LS; a 4.8. Since 4.8L converts to 292.9 cubic inches, I decided to round down and call this a 292 swap ![]() The 4.8 came from a 79K mile 2003 Tahoe. I bought it over a year ago and slowly gathered parts. It's got a mish-mash of truck and Camaro parts for the accessory drive and a LS1 'vette intake Very cool build! Can you explain the mish mash of truck and Camaro parts of the Acc drive? Maybe what is from what or part numbers? Or what you did to make it work? the water pump looks like the l99 part number 19207665? Thanks in advance |
