Need help estimating horsepower for clutch

[01Crewcab7.3]

I plan on buying my new clutch soon but do not know if I should go with the 500 hp version or the 600 hp version. These are the mods I plan on running, and I do a fair amount of towing.

Hutch/Harpoon
Fuel bowl delete/RR
Stage II 160/100 Injectors
SRP1 HPOP
GTP38R w/ 1.15
PHP FU2 with 140E as one setting
And I already have the obvious 6637 and 4" TB straight pipe.

Just looking to see if anyone knows what horsepower range I might be in and if I should get the 500 VALAIR or the 600. Thanks for any input or suggestions!

Con ofe from south bend seen multiple trucks with close or more mods beat the living hell out of there rigs and tow heavy with no issues nothing beats good tuning and a good clutch

So you think 400/800 will be enough?

Never mind found a 450/900 one, that should hold up right? Also should I replace the flywheel at the same time or no?

If you have a dual mass in your truck right now then yes I would get a new single mass flywheel

Sorry for all of the stupid questions but how do I know if I have the dual? Or is it obvious once I see it I will know?

If its a factory clutch then it's a dual most people put stock clutches in stock trucks there's no way to tell until you pull it apart if you picked up your truck bone stock I'd be willing to bet you have a dual mass
