I'll offer just a few minor comments from practical experience.
I owned a Scarab 240Z running a 750 double pumper, Stroked LT-1 that put a ****'va lot of power to the pavement that ran flow through dual 2 1/2' 's that crossed at the rear tranny area. It was a total animal or a Z that I would not run other than straight line.
I now run a intercooled, Turbo'ed L28 in a 73 240Z flow'in down and out a single 3 pipe and 3 SuperTrapp with 14 spacers.
The car turns the 1/4 in 13.3 sec, 102 mph in with skinny, hard street tires, and whips through curvy mountain roads with the greatest of ease. From a light most V-8's best me, but from 60 mph very few V-8's can stay with me.
Just some comments from experience, but I remind all that Electromotive did once build a 550 + hp L series engine so be sure you all look at all the options.
For an interesting comparison of V-8's in Z' and dual exhausts you all might look at one of the latest V-8 customs that I am presently writing an article about. It's a gorgous Lexus LS 400, 4 OHC, 32 valve V-8 in a 73 240Z autocrossing convertible with corvette rear look with dual exhausts. Maybe it will give some of you some ideas.

Below you will see another autocrosser running a Ford V-8 with the full nine yards of hardware.
