Default Tuatara - LS with a flat plane crank?

https://www.sscnorthamerica.com/tuatara

Website says that Nelson builds the engines for this super car, but also lists that the engine uses a flat plane crank. From the pictures, it sure looks like an LSx based engine to me. Anybody else know about what's inside these engines?

Maybe it’s the engine that uses the billet block that he has in some pics or YouTube promos

Is it LS, or LT based ?

No real clear shots of the engine, but port angles on the intake would make it seem LT ?


At least it isn't a SBE.

What about 331mph ? lol

More impressively though...it did it with ease. There's no doubt there's a fair bit more left in it, whether aero, tyres, the road etc are all up to doing "safely" who knows.
