What’s parts will be needed that ive might have missed for the swap or has anybody done this type of swap? I will be getting a LS 427 1500 to 2000 hp deciding witch package to go with and it comes with full engine and transmission everything from wires efi kit, wires. The Whole works from motor to transmission I will just be adding headers, exhaust line , upgraded drive shaft, rear diff. The thing I’m stuck on is this so called swap in and out plug and play since am going from LT to LS 427 anybody have experience on what I might need for it to fitment issues ? New transmission crossmembers ? Motor mounts I just want to make sure there’s is nothing missing or I might be over looking prior purchasing. I understand if it was old to new but am here going from LT to LS on the truck project truck I must say. Anything helps those who have experience. Thank you
I go by Dirk, I currently live in Nebraska... yeah, another Nebraska guy. After 27 years, I am back into Chevrolets, and I have purchase two Chevy trucks this year, only they are 50 years apart!
Just bought my 2014 Chevrolet Silverado 1500 HIgh Country (5.3/RWD) and;
In March I purchased a 1964 Chevrolet C20 Fleetside which I currently have stripped down to the frame in my garage with a crap ton of boxes of parts to start my build on it!
Look forward to learning a lot from this forum, and maybe meeting some of you someday!
just joined the forum so i guess im the new guy with an old truck...
tis the season to be wasting money...
plan is to ditch the 18's and go with some 17" torque thrusts with tall tires out back and then maybe re-address the ride height.
currently 5" in the rear and 4.5" up front.
it had slightly sloppy steering so I changed out the steering intermediate shaft for a nice u-joint version.
the doofus before me "changed the rear brakes" but never adjusted the shoes properly so the wheel cylinders started to seep and ruined the shoes on one side so im going to replace both wheel cylinders and shoes.
so once I cracked open the rear end I was pleasantly surprised to find out that the open diff was completely smoked.
I don't even know how it held together on my trip home. kinda scary.
sucks that I had to shell out cash I wasn't expecting to but at least its only the diff and not the entire housing etc etc.
I decided to go with an Eaton limited slip that is currently in route.
im going to do the diff swap, diff seals, axle seals, wheel cylinders and brake shoes all at once.
hope to have it buttoned up by the weekend.
I also decided to pep up the gear ratio from 3.08 to 3.42.
it will hurt fuel mileage slightly but once I ditch the 18" wheels (current tire diameter is 28.5") and go to a 17" setup (which will have a tire diameter of 30") it shouldn't be too bad.
so while im waiting for the rear end parts to arrive im going to continue to pick away at the list of little stuff I want to do.
*continuing with the long winded post*
I took off the old 13" billet steering wheel it came with and bought another 15" comfort grip steering wheel I noticed that the previous owner for some reason ditched the column spring and signal cancel cam/horn conductor.
so I sourced both of these little jerks
in addition to that he wired the horn to a separate switch under the dash...!??!?!?!
so ill wire it back up the column.
I also ordered a few firewall boots that were missing and letting TONS of cold air into the cab
one for the brake rod
and one for the steering column
there is also a hole in the dash where the cigarette lighter went and it bothered me so I ordered one of those too...
ill *hopefully* get around to changing out the passenger window regulator that gets really difficult halfway down.
I already bought the part just need to find the time. I keep putting it off since its not that important...
these CPP sway bars came in from summit over the weekend so ill try and get those on too.
Ill prob be "sick" on Friday and just take the day to button it up.
I may even cruise over to the truck shop and pick up some new cab cushions (the current ones look like they needed replacing in 1993) along with a repop correct style 10" rear view mirror and wiper washer motor.
once I get all this stuff sorted out ill start to plan out the next phase...
the big question...n/a or boost
