Another option for the Camaro is to swap in a late model (2002-2009)4200 vortec inline 6 out of a trailblazer. The are EFI from the factory. If you use the 4l60 trans that came with them, its a lot easier than adapting other trans.
They are either 275 or 290 HP from the factory. Add a turbo with 8 psi.. = 400hp...
The Camaro has lots of room width and length wise for the engine - might close height wise but people have put the 4200 into a 3rd gen camaro which has less hood height.
There are a bunch of inliners near Reno that have swapped the in the engine.
