I have a 2001 Silverado 2WD that I would like to do a V8 swap in the place of the V6. Any ideas or suggestions? I have about 85K on the truck and want more power. I would be sending the trans out to a local friend's trans shop to be gone through...

 

One idea was to buy a totalled Chevy and do an engine/tranny/wiring harness/computer swap. The other idea is to go with a late model 350 out of a Suburban/Tahoe since it would bolt in. Any help out there??

 

Thanks Guys. :confused:

I think most people find it non-cost effective to do this swap. You'll need engine, wiring harness, PCM, front springs. You may have trouble getting it inspected in some states if it does not have the original size engine that it was manufactured with. Now if you had a donor or a wrecked truck you could get cheap, you might get it done. By now, you may find some good deals on a used engine.

We want pictures as the work progresses!!! This should be cool! :rolleyes:

 

I'll be sure to take lots of pictures when I do it.

 

I think this is a project whose time has come Mike. I pondered it over and over but never got there... you really should.

I've already spent half of what it WOULD have cost in PDR :rolleyes:

 

Sadly though...I honestly don't think it'll happen unless the motor in it craps out. I'm getting married in a week and a half, so I expect kids in the next couple of years...At which point, a reg-cab is really not feasible. So I'd be looking for an ex-cab, CC, or Avalanche at that point.

 

You never know though. I might fall into a deal on a motor, this one may sh*t itself, or whatever...

That one had less than 10K from new when you got it. I doubt it dies anytime soon. I have first dibs on buying Fred back when you go to sell it. DEAL?

 

 

HOLY CRAP!

 

You are getting married? Holy pajeebers frikkin hell. I never thought I'd see the day.

 

Congrats man! :rolleyes:

Yeah I know...I'm just joking anyway. I've spent a LOT more money on MUCH stupider things. Plus, she's so frugal it's unreal. She worked her way through college working at 7-11 (no grants, no loans) and managed to save up enough for a downpayment on a house in the process. I'll make that money back in the first year we're together :rolleyes:

 

And it's damn well taken me long enough to find her! I'm freakin' THIRTY SIX!

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
