6.0 stroker
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.
And....

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".
IMO a stroker makes no sense till looking for a car that needs a rollbar. Most aren't aiming that high when starting.
Sure, one could make an argument that a cage would be beneficial at the 500rwhp level - but 99% of the guys at that power level don't run them.
You're talking about two completely different classes of gearheads here, while the OP is simply wondering if a 4.000" Stroke Forged crankshaft is reasonable in a 6.0L block. This doesn't even take into consideration that many have taken this exact block to 4.125" "safely", but obviously sacrificing "reliability".
"Reliability" and "racecar" are two words that really don't belong in the same sentence.
