so im trying to decide which junkyard motor is right for me im liking the ly6 because the 6.0 bore with l92 heads factory heres my plan

Speed Density Tune/E85

Junkyard LY6
LS9 Headgaskets
ARP Head Studs
ARP Rod Bolts
LS7 Lifters
Comp Valve Springs
Custom Grind Boost Cam
Edelbrock Intake Manifold w/ fabricated elbow
102mm throttle body
120# injectors

all of that with an s475 turbo im just looking for the MAX power this motor can take hoping in the 750 ballpark i know the rods are the weak point but has any one pushed one this far? people are making 600+ wheel from a 5.3l and HP magazine did 1200 from a 4.8 with mild mods i cant see why 750-800 wheel couldnt be done from a 6.0 w/ l92's on e85 with a perfect tune all i really need is about 700 to get it where i want it to be but more would be nice and i have to run stock bottom end internals and a production head so im stuck with stock guts

Horsepower depends on your $.
Pistons, rods, heads, cam and valvetrain and im sure you can push out around 1k hp.
Whats your goal for this engine? Track? Dyno queen? Or a very fun street car?
700 whp is very obtainable with pistons, rods and some boost.

Need to keep the stock rods and pistons

The normal limit, at least on a stock shortblock ls1 is around 550whp. Id say around that is the "safe" limit.,
