Default Big block engine under small block hood?

My big block is getting finished up at the machine shop and I'm getting ready to do the swap. Has anyone heard of any intake setups/motor mounst that would allow me to use the small block hood?

I put a bigblock in my 75 and even used the high rise LS6 intake and with a 2 inch air filter and cleaning up the underside of the hood it fit.

Even with an LT-1/BB hood in that era(68-72), GM used a low, low rise intake manifold to fit under the hood.
