My point is max power is not always the objective! P.S
Not a valid analogy. Everything you mention is more expensive than the ls option. At present the v6 you want is going to be more. From a cost:power perspective the ls wins, for now.
Doesn't every Japanese luxury sedan come with a 300+ hp V6 these days anyway?
That aside, it might be an interesting swap.

Yes, one of these, just the v6 version! Glad to hear people are starting to get into these so soon! Callaway and linginfelter allegedly have designed supercharger kits for the 5.3 you pictured but I have yet to research it! It's rumored GMPP will offer it as a create engine with stand alone controls for swaps! Please keep us informed of your progress! I

How do you figure the " standard engine" offered in these trucks will cost more than the " optional" engine? When these do hit the salvage market it's common sense that there will be more " standard " engines available, and since it is a v6 and will be lest desirable among most enthusiast, the supply and demand will obviously keep the price lower than its v8 " optional " counter parts! Yes a ls1 v8 would defiantly be cheaper, but my original post plainly states I'm inquiring the new ecotec engines! ( 2014 ) gm truck engines! But my point still, the 4.3 ecotec is rated at 285 hp and 330 ft of torque, that's more than the current 5.3 that 1000's of us swap into our cars and trucks! That's all I was saying! So compared to that plus the 4.3 will be lighter with a factory steel crank ( allegedly ) dont quote me on that, the 5.3 ecotec is said to have a steel crank as well. Why should I swap in a v8 ( factory LS ) instead of this new 4.3 v6?

some 5.3 are over 300 and, any of them are a cam away from much more than that.

its not just about the initial swap, most people upgrade from there.

Here we go again! You guys are obsessed with the whole a v8 is this and now it's " not about the initial swap " I argued my point about if its not about the swap its about future upgrades then just swap in a nitro blown hemi! That's the best rite? Oh wait.... How about a Pratt and Whitney turbine engine!!!! Yea that's it! I swear!!!!!

I thought we were all into building bastard half-breed cars here? Who cares what engine is the "best?"

The V6 will be smaller and more compact than the V8 and make similar power. If the V6 is LS based, I'm sure the aftermarket will catch up very quickly and we will see cam-only 4.3s making respectable numbers.

There's no sense trying to talk any sense into him folks. If you don't agree with him he is just going to keep bringing up nitro-blown Hemis or whatever.

So I'll make it easy. The V6 is by far the better, cheaper, faster, more reliable, more interesting choice. You will find thousands of them at every salvage yard with 1,000 miles or less. You will hit zero snags swapping in the V6, and all of the swap plates, exhaust manifolds/headers, exhaust, front accessories, mounting brackets, etc are free from Summit Racing with discount code SMMTRCNG2013

so go do what you want and stop trying to justify it to everyone.

clearly you must not be convinced if it so great if youre looking for validation.

They are based of the platform of the new gm truck engines for 2014. These are called ecotec 3 wich is a stupid name I think, but they are the new LS series if you will just different name. The v6 is just a 2 less cylinder version of the v8 just as it was in the 80's when the 4.3 was based off the 350. So I consider it a v6 LS engine

they are not the new ls series. they are the lt series.

if they were the new ls series, they would be called ls, not lt.
