I'd say they are hands down the best route, but not many americans are ready to throw down $3500+ for a intake that they don't even know fits or not. However, I do plan to make it fit in mine, no matter what. Hence the right up when I'm finished.

Now I know you said "street-car" but this thing sounds pretty max-effort to me. If youre not really worried about drivability, and i doubt you are with a 750 bhp solid roller motor, in my opinion id say to just open her up with a sheet metal intake. Sure youll lose some port velocity which aids drivability around the street, but it dosnt sound like this is what youre after. A sheetmetal intake with huge port volume should flow like no other. Atleast in theory.

The edelbrock intake with fuel rails is 400 from summit racing. A custom elbow is need to run the 90mm or whatever tb you plan to run. Cost for us was 195 shipped. Porting price is dependent on where you go. I would guess around 400 would be a good ball park. I don't know what the difference would be between a ls7 combo and a etp 240cc head and fast 90 intake. Never tried it so couldn't comment. The ls7 head stock is like a 250cc port, and intake is supposed to flow well.
As for the stock computer. It's max value is for 8k. If you plan to shift at 8k, most of the time you won't shift at that exact rpm. Meaning you will over rev that point. The stock computer only goes to 8k so there is no way to try to shift it right there. Normally I set shift point about 400rpm lower then rev limiter. It gives you some breathing room for shifting so you are not banging the limiter. That is why I suggested a 7600 shift point. If you want to rev higher then an aftermarket computer is the way to go.
