First Gen F body ride height question

[Fluxion]

I have a 67 firebird that I am working on and I am contemplating quite a few modifications. I have a question about the ride height I see on quite a few first gen camaro's. All the cars on here look great and want a similar stance.

How much clearance should there be between the pavement and the bottom of the rocker panels? I want it kind of low like 4"-5 at the rear of the rocker and maybe a little lower at the front. Is that too low on a car that will be driven? I know the front subframe and headers will probably be a little lower. What kind of ride height would be recommended for a car with something like a Lateral dynamics or Art Morrison 3 link in the rear?

Thanks for any suggestions, Bryan
