The L98 on your list caught my eye as I was unaware that GM brought back that designation that was applied to the older tuned port injected engines starting in 1985.I assume the Coyote will have similar ECU specs to the supercharged Aussie 5.0 alloy V8..??
These guys are fitting LS [L76/98] V8's into RX7's also..
The good part with these engines .. They have forged assembly..

These are the turn key engine weights..
LS1 = 252 Kgs. (part number 25534322 - discontinued)
LS2 = 249 Kgs. (part number 19156261)
L98 = 246 kgs. (part number 17822015)
LS6 = 246 Kgs. (part number 17801268)
LS3 = 244 kgs. (part number 17804137)
LS7 = 239 Kgs. (part number 19165058)
The LS series engines here in the states use cast cranks and the powdered metal rods except in(afaik):
LS7 in the Corvette ZO6 with forged steel crank, forged titanium rods, forged pistons
LS9 (6.2 liter) 2.3 eaton TVS supercharged ZR1 Corvette with forged steel crank, forged titanium rods, forged pistons
LSA (6.2 liter) 1.9 eaton TVS supercharged Cadillac CTS-V with forged steel crank, powdered metal rods and hypereutectic pistons
IMO the biggest problem with 1uz-3uz applications especially with the 1998+ model years are the weak transmissions. The pistons and rods are also weak but that is fairly easy to fix. Much harder to get a smooth and reliable transmission for over 400hp applications. As far as engine choices it is hard to argue against keeping the UZ base and adding turbos for the cheapest and most powerful solution. Swapping engines and getting all of the factory interelated functions adds a huge amount of time and that = money.
JeffTsia over at CL has been working to make the A650E (the lexus 5 speed automatic used from 1998-2003) stronger as he is using it behind his turbocharged 2jz. He has developed MUCH stronger sprag's for the transmission. Even so they are still not bullet proof. Not sure of the higher power capacity but may be in the 500hp range as long as you do not abuse the 1-2nd shift.
