Impala Wagon Swap build. https://cimg9.ibsrv.net/gimg/ls1tech...6faeeebbc9.png https://cimg1.ibsrv.net/gimg/ls1tech...0c16dcf68b.png Got most of the big parts, so might as well start a build thread for it. Car: 1978 Impala Wagon. It big, Its ugly, but it is cool. Currently a Roller. Fairly solid for a car from the Rust belt. Needs its TLC for sure, has some rust but nothing terminal. Engine: 2005 LQ4. Bone stock truck 6.0., will be backed by a 4l80e most likely. Plan: Engine will be pretty simple. Swapping some 5.3 heads on for a nice compression bump along with a custom cam trying to keep power in the usable range. Not going for a drag car, just a nice cruiser with plenty of power to make it fun to drive and motivate it nicely down the road. Car will be pretty stock. upgraded sway bars so it doesn't handle as much like a boat, nice wheel/tire combo. eventually painted and made to look respectable. Just want something to take on vacations/road trips. could possibly end my being my DD https://cimg3.ibsrv.net/gimg/ls1tech...15316d4c54.jpg |

If you get the T56 installed, you'll love it, I run a T56 in the wagon in my sig. They're a little more work to install, but well worth it. |

the idea was originally discounted due to cost of a T56, but I have a line on a pretty cheap one that may just work out for the best....... But hell.....that's just me. KW |

I would install at least some 3.73 gears to go with that transmission. But hell.....that's just me. KW I run 3.73's in my wagon...they work great as far as I'm concerned... |

I love wagons. Will definately be following this. |
yea NA 6.0 with a t56 and 2.73 gears would be hilariously long winded and not enjoyable. 1st would go to like 78mph. |
I run the 2006 GTO T56 (TUET-2066)...it has the 2.97 low gear ratio. This makes for quite spirited low gear blasts with the 3.73's. I don't think I'd go any lower than 4.10's unless your going to spend a lot of time at the strip. (The Camaro/ Firebird T56 has a 2.66 low gear) With a 28" tire, I'm running about 1900 rpm at 75 mph. |

Honestly, if I was starting with a T56, I would definitely go with the 4.11's. I had installed the 3.73's when I originally had the 4l60e.. I would even consider the 4.30's if it was me.... That BIG beautiful bitch will feel nasty either way. Good luck on the build, keep posting. |
Hoping to get the engine home to my house to work on it at my leisure this weekend. Nice having a large garage to work out of, just sucks it is 30 minutes from my house. So home it comes. Placed the order for the Cam/lifters/springs/pushrods just a few minutes ago from Cam Motion. gonna wait to order gaskets till I get it all pulled apart to see just how far i need to take it, see if it needs cam bearings or rods/mains instead of just doing a top end kit. Cam Motion suggested a custom cam. 220/228 .595 lift 109+2 Harness will come off to be taken to a buddy and have him cut it down for me. Doing a little work trade for it. Engine will be built over the winter. Just have to fully sort out if i am going auto or T56. |
Any kinda wagon with a manual is badass especially a big ass boat like that one |
https://cimg1.ibsrv.net/gimg/ls1tech...593626e412.png https://cimg6.ibsrv.net/gimg/ls1tech...309c8b1779.png Cam shows some wear, but otherwise the engine is seeming to be pretty clean. Have not pulled the heads yet, as i have not pulled the balancer due to lack of proper tools at this time and figured a bit of compression would assist with that. Cam is due to ship thursday, Hopefully ordering the rest of the gaskets by the end of the week as well. T56 is still up in the air. Little bro is up in the air as to what he wants to build, which leave my build up in the air as well. His choice is between LS1/T56 swap a Volvo 240 wagon or build up his 2012 PPV caprice. |
Wagon Hi Underpowered What a cool project!! I also am wanting to do a similar swap. I have a 94 caprice wagon. Would like to do a LS3 or 6.2L but they still get gold for those around here. We will see. Anyway I am looking forward to your project!! https://cimg7.ibsrv.net/gimg/ls1tech...2b4e359637.jpg My 94 Caprice. |

Anyway I am looking forward to your project!! My 94 Caprice. Just gotta keep an eye out for a deal. I wanted a 6.0 but assumed i would have to settle for a 5.3 due to my budget. But after a bit of looking, bought the 6.0 from a friend for $1200, but sold the Trans and T-case that came with it for $800. Ended up with only $500 in the complete 6.0 with full harness and ECU. Dropping of the harness to be cut down tonight and picking up a a few tools to help with disassembly as well. Hopefully it will be down to the short block by the weekend. |
