It'll make around 800 hp, and probably weights similar to an iron LS. It also has the Chevy bellhousing bolt pattern on the back. I'll likely put a T56 Magnum behind it, or one of the T101 based Nascar 4 speed dog boxes. I will be using EFI, and try to keep the CAN dash working.
So my questions: As I have the engine, but not the car yet. what is the typical crankshaft cL height from the bottom of the front suspension crossmember on an LS swap. Does that allow the T56 Magnum to fit in the tunnel with the factory reinforcement removed? I'm wondering about hood clearance? How much room is there from a bottom of the hood, to the bottom of the front crossmember? What has been done for custom hoods with more clearance?

Crankshaft centerline: I'm gonna send you on a little hunt for info here... Look online for the crank height from the oil pan surface. Plus the height of the Canton racing LS front sump road race pan. That's about where the crank sits from the top of the cross member. Very little clearance.
T56 will fit in the transmission tunnel with a little hammering and removing ALL of the stock bracing. No cutting of the tunnel itself is required.
Hood clearance is fine with manifold height maxing out at around 6.5 inches. The FAST LSX manifolds and the GM car manifolds fit without issue. Some people have had to modify their throttle bodies to make them fit though.
Get on the LS Swap BRZ groups on Facebook. Someone just developed and i believe currently has a group buy open for a carbon fiber cowled hood intended to fit high rise manifolds and positive displacement superchargers. I don't know the height from the cross member. I just know it's only a couple inches more than an LS engine with car intake manifold
