What, another LS swap cost thread?

[Macguyver]

Here is something other than our usual suspension tech help for you guys to chat about.

Naturally aspirated street build.
So you found a 6.0 and 4L80 for free like the story goes.
You ask yourself... "What is the cost when done?"
After reading online you find you need a decent cam, (one of our favorites .585", 228-/230-degree duration split, and 112-degree LSA). <--- Great for the street btw.
Maybe some mildly worked 243 heads and some valve springs to round the power up a bit.
Installation accessories, motor mounts, oil pan, exhaust, front engine accessories brackets and all associated seals and gaskets.
Maybe an aftermarket fuel management system, injectors, trans controller, radiator and fans.

All this for roughly 520 hp at 6,000 rpm and 500 lb-ft of torque at 4,600 rpm.

Again...What is the cost when done?

For reference...
a well thought out street SBC 383 will make roughly 495 hp at 6,000 rpm and 495 lb-ft of torque at 4,500 rpm.
a well thought out street Mopar 383 will make roughly 530 hp at 6,000 rpm and 520 lb-ft of torque at 4,500 rpm.
a well thought out street Ford 351W will make roughly 490 hp at 6,500 rpm and 470 lb-ft of torque at 4,500 rpm.

It shouldn't be hard to get about 465,000 answers cause everybody is doing it...……………………..is this a loaded question?

More than one expects to cost, more than a SBC swap, not as much as a divorce...

Dunno, but I want a free 6.0/4L80E.


Seriously though, it's hard to hate on the LS world. Parts everywhere and getting cheaper every day. Wish I had an appropriate car to dive in with.

I'm not finding it difficult at all. I hate small block chevys, so it just comes natural. Back in my day, taking a 350 out of a pickup, throwing heads, intake, cam, rockers and headers and nuking it with nitrous until it blew and then doing it all over again showed a serious lack of imagination. Going fast is NEVER cheap, and anyone who claims to be doing it has a warped sense of 'cheap' or they really aren't going that fast...………..

if they're doing it cheap and making big power, they like changing engines. I like working on my car, but let's be serious. Do you really want to yank it out every 2 weeks?

Yanking it

If you never drive it you can get half a summer out of it

So cam, springs, headers, heads or port work, intake, carb, ignition source, and a free 6.0 should cost about $3-4000? Maybe $5000. I don't know if that's cheap or not.
