TRUE costs of a LS Gen II/IV swap
Permalink  
 


ok, I see it all the time in the forums, "Drop in a take-out LS engine"
then I hear about the hair dryers and all the related

Lets see the costs.  NOT hating. NOT trying to stir anything up.  Just facts, educate me.

Headers
Oil Pan
Oil pan related
Brackets
Motor mount adaptor
wiring
most run a fancy fuel tank
most up the cam and springs....
other stuff I have left off from those who did this.....  I sold JeffJeff BBC Nova offset motor stands that allowed a 5.3 stock ext manifold to clear the 69 Nova steering

next step

How about the costs of 1 or two turbos and what you need to put them into the engine compartment
turbo(s)
coolers
misc stuff
I know Mikey likes to FAB

It's not as cheap as people say unless you go bare bones.

That's kind of a trick or loaded question.

It would depend on what you are putting it into to begin with, and what motor mods on top of that.

It would be like asking, How much to make 1000hp with a BBC.
It would depend on how you went about getting it, N/A, nitrous, boost along with parts quality and type.

A wrecking yard 454 with a few parts and a butt load of nitrous will make 1000hp for cheap but not for very long - vs. - a 1000hp Reher Morrison N/A motor.

Junkyard 6.0L, around $1k with accessories.
Headers --$500-700
Oil Pan --F-body pan with related $400
Oil pan related --see above
Brackets --??? what brackets
Motor mount adaptor --$100-150
wiring -- spark and fuel control $700 for worked OEM? - $2k aftermarket with controls/features, trans controller add $600
most run a fancy fuel tank --$500 - $1k depending on how cheap/capable you are and HP level needs
most up the cam and springs....I did re-cut cam, springs and trunion upgrade for around $375-400
other stuff I have left off from those who did this.....  I sold JeffJeff BBC Nova offset motor stands that allowed a 5.3 stock ext manifold to clear the 69 Nova steering

next step

How about the costs of 1 or two turbos and what you need to put them into the engine compartment
turbo(s)--Sky is the limit, figure $1k -$2k depending on wants
coolers -- $500 + shipping for my 2
misc stuff--Turbo headers and cold side kit $1,500 on the cheap side.  Oil coolers, lines another $250.  Not listed is radiator or hose adapters to fit what you have, P/S adapter fittings, different accessory bracket setup if needed or wanted.  Other stuff I'm not addressing like different intake or drive by cable throttle body, possible transmission adapter plate for an older trans, the list goes on.  
I know Mikey likes to FAB


 Just my experiences and research for my own plans in bold, still have a lot more to go.  My advice, make a list of parts and go searching.

My own engine for my '91 V3500 was $2,300. What I got for that was a 2004 LQ4 with 95k on the odometer. It was in beautiful shape and was removed from the vehicle like a surgeon did the work. I was a full drop out with the wiring harness, TAC module, PCM and the GMC Yukon fuse box. I put in the ORD crossmember which I already had that fixes the interference issue with the stock pan, so no changes there. The first set of adapter brackets that I bought had all kinds of problems with interference. They were like $105. I'm sending those back and I now have a set of BRP Muscle Rods conversion mounts. They were $300!!!, but I test fit them and they fit like a glove and solve all of the interference issues. I have already made CAD models of them and I contemplated sending them back and having our fab guys at work punch them out and bend them, but that would just waste more time.

I am looking at buying a set of headers from Shoenfeld. I hear they are about the only ones that have a great product that fits to my truck and the O2 sensor bungs are updated to put the O2 sensors for proper clearance. If you want to tune yourself and not pay someone to do it, you will need a copy of either HPTuners ($650) or EFILive ($900)! I have a friend that has HPTuners, so I may go that route and just buy a $100 VIN license and borrow his laptop.

I already have the 4L80e transmission so that is plug and play, but I will need a higher stall convertor for going from a BBC to the LS. Then I have to deal with installing the EP 381 fuel pumps in my 2 tanks and running the Corvette filter/regulator and making some fuel lines and upgrading all of my soft line connections to FI rated stuff!

The other bits are MAF sensor, the DBW pedal that fits my truck, cooling hoses, some mods to my current radiator to add the air bleed connection and cap off the heater hose connection as the both the hoses now go directly to the engine, custom AC lines, custom oil cooler lines, air intake ducting bits, and lots of time spent with electrical wires!!!

I am still contemplating a cam swap before I finalize the engine install and possibly milling about 0.030" off of the heads to bump up the compression.

As you can see, it all adds up! Sometimes I wish I would have just did a stock rebuild on the TBI454 and got the thing back on the road, but I am sure the LS engine will be a great runner when I am done and should improve my fuel economy slightly.

I have a spreadsheet when I did my 66. Off memory I think I spent about $4.5k. Engine included which was $1k

How much was the Mini Cooper George?  Just to put a normal $5k GENIII/IV build with fuel injection into perspective.  Once the capable enough supporting systems are in place swaps/upgrades would be easy.

Depends on what you want to spend and how much power you want to make. The good news is you don't have to fabricate much or figure out anything these days. Its been done and plenty of manufacturers make what you need to make it pretty painless, but that will raise the cost. If you're patient (I'm not), if you can fabricate (I cant), if you have space for some tear down of a purchased donor (I don't), have some good understanding of electrical (I don't), then the whole thing can be done very cheap. If you buy it all off the shelf its going to be what some would consider expensive.

 The 433 BBC I was going to build would've been more expensive than this 6.0L engine will be.  That of course does not include the turbo or A/C stuff.  IMO, it is a cheaper platform than the big block for what I was planning to do.

thanks for the responses folks!
I guess other cars would be easier fits than Mikey with the a/c and turbos being a challenge with the available space.
I'd think a Chevelle or Elky without hair dryers, right around what Brett said $4k, less fitment troubles
