Lump ports and intake preps are important for forced induction engines as they are for n.a. engines. If you have a more restrictive intake tract you'll require more boost to do the same job as a more flowing intake setup - draining additional power from the crankshaft and creating additional heat (bad). Do the forced induction and the intake work for best results.
I would also bet you'd make the most power with the supercharger. I think you'll be limited by the 87 to a low boost level, but still make more than the n.a. engine. And then hey, when you feel like it swap pulleys drop in some 94 octane and go. It's all a cost/benefit thing. For the extra work I'm not sure you'd make THAT much more if you're restrained to 87 .
Just my 2 cents. Greg
