It's not just about the drives, make it all bigger!

I still think it has more in it too

Like anything how you treat it will be the final tell.all.
I don’t think the SC can handle 1000HP , maybe the SCX lower . As said previously, the SC in just XR gears

#4500 empty. that is not a light boat for a single, Twin engine splits the load.
My 34 SCARAB was #10,000 dry with Bravo uppers and Imco -2 SC lowers, 509 CI at 650 HP

I run sc lowers on my tiger at 850, no issues as of yet... i will do dual shafts down the road as I'm taking it to 1000 per side.

I have an SCX 1400 lower for sale with only a few hours on it. Just was completely gone through and is 100%. They are bulletproof. It is 1:50 gear ratio. I have a 1" spacer for it as well.
