6.0 stroker
If that is the idea you came up with then I strongly suggest YOU not look at building a motor, you are WAY too green to be able to make the right choices.
4.0 stroke is common in stock blocks but if you can't get that then you need to stick to air filter changes for awhile.
Not trying to be a dick but if you dive in at this point you are going to cost yourself a lot of money and make a lot of mistakes.
Besides displacement increase is about the worst return on your modification dollar, there comes a time when stroking becomes a good way to make more power but people want to go there MUCH too quickly.
Ported heads and bigger cam can make a lot more power than stock and those things need to be upgraded with a stroker too.

I said he was too green, not that has was never going to be up to it. We all start somewhere and I am damned glad that at 20yo when I wanted to do stupid things like a stroker with stock heads and cam that I was too broke to make that mistake and instead kept researching and learned a lot before I began spending money.
IMO a stroker makes no sense till looking for a car that needs a rollbar. Most aren't aiming that high when starting.

Yes and I agree which is why I said your statement had some merit, just keep in mind that over the internet people can't tell the tone is which your saying something. so naturally your first post came off a bit harsh. It's all good though, this is a place for learning 
To the OP....if you are indeed running stock at the moment, I would suggest looking into a heads/cam package first, enjoy the gains for a while, and continue to do research about stroker kits, then make an informed decision on your next move. I think you will be very surprised at what the right heads/cam package can net you 
Sorry I asked question wrong. That's what I hate about forums lol. I have been around engines all my life. I've worked at same MAck dealership for 27 years. I built a 6.0 for in a drag car two years ago with great results. Just plan on going with forged internals for next build. Was wondering if you can strike stock block or not. I heard that it wasn't a good idea but wanted to listen to advise. By the way current engine running 10.70's in the quarter mile 78 camaro

A 4" stroke is not a problem but does come with some increased wear on the skirts because the skirts do pull out of the bore. Many people have ran them for 50,000 miles with no problems yet others have had wear issues well before that. If the clearances are closely followed and cylinders prepped accordingly then it should live a long life.

That was a bit harsh, no need to make someone affraid to ask questions and learn. your advice has some merit but damn, no need for the put down, that was a bit immature in my book. plus he never said money was an issue, maybe he wants to experiment and learn as he goes. just my .02
I have a question for you. Are power adders included in your build?
I only ask because there have been a few discussions on strokers and power adders.
General consensus seems to be stroker with Nitrous or Blower but not needed for turbo builds.

Well IMO, longevity is what I look for in any build. Stroking a 6.0 block with a 4 inch crank is not a good idea in my book mainly because, yes, the skirts do wiggle around at the bottom of that blocks sleeves. Now if your going to spend that money, I'd just forge it, slap a good set of heads on it and cam package and have some good long fun.

My apologies. I get a tad livid when people jump to conclusions about someone's overall knowledge or capabilities just because some small bit of information has eluded them somehow, or they didn't phrase their question the way they wanted.
273 intake duration @.050? That has to be a typo... Maybe
& what alcohol are we talking? E85 or Methanol? If Methanol, do they run that lop-sided of cams NA? I'm curious because with the vaporization I could see it being a necessity with it's correlation to usable charge density.
Meth loves forced induction for that reason & that is primarily what I am accustom to seeing. I would love to see a vid clip to hear how it sounds.

OP needs to define longevity, 2618 pistons will last a long time on the strip, but on the road my understanding is the ring lands are junk by 20K miles, 4032 can last longer on the street but that is because they are harder which can let them be damaged more easily if detonation should occur.
Since the OP says 5800rpm stall, slip and glide, and alky it only sees a road from on top of a trailer.
Honestly given the description, forged rods and some sort of piston upgrade would be prudent due to rpm and a crank a reasonable thing to add once going that far.
To go faster I would look at a different tranny unless the car is really light in which case I would try and figure out why it is so slow. The comment about slow 60ft suggest a tranny with more gears could help.
Guys have gone 10s in streetable(not daily but streetable) LT1(old 23degree 5.7l turds) and LS1 cars on pump gas.
What does it weight? 10.7 is impressive if 3500lbs at 3500ft, sad if it is 2500lbs at sea level.
What does it MPH at what elevation?
Far as knowledge level, the idea that you can't stuff a 4" crank into a stock block is about as absurd as "you can't modify an injected vehicle".
