Default Interested in your opinions - gas tank and pedals

Hi all y'all. I'm interested in your opinions on the following:
1) I just finished installing my new ss gas tank and I'm wondering if I've installed it a little too low. I have about 6" ground clearance at the lowest point. What are some of your cars running for ground clearance?
2) What are the pros and cons of a floor mounted pedal assy (Tilton makes a nice unit with drilled pedal arms) vs hung pedal assy's. My car currently has a hung assy with the mc's sitting on top of the footbox (in the engine compartment) and I would like a cleaner look by getting the mc's off the footbox. Any thoughts?
Thanks
Greg

I know my car has less than 6" of ground clearence. Probably not much more than 4" The key to me would be NOT to have the oil pan or gas tank be the low points. In my case frame rails are protecting both. The fiberglass up front would be the first to hit anything, but after 40,000 miles it's still in one piece. I do seem to scrape the bottoms of the sidepipes about once a year.

I have no direct knowledge about mounting the brake pedals. Just be sure the floor does not flex when you push on the pedals.

The foot boxes on NAF's are thin. They'd need some beefing up before mounting floor type pedals. I looked at changing my setup out with the tilton setup too. Decided it wasn't worth the time and expense.

Greg, check my pics, very frustrated with the tilton hanging assy..
Removed and built this, accessible from top and bottom plus, clean engine bay.
A little labor intensive but worth it..........

Thanks for the input guys. Great pic Perry. I was planning on a similar setup using a steel plate fastened to the frame rails and mounting the Tilton assy to the plate. My footbox is quite long and has a dropped area where the pedal assy would go.
Any thoughts on pedal length and ratios? I know Tilton's tech line is pretty good, but real world advice also helps.
Thanks
Greg

Truth be known, I went to ERA's web site and printed their paddle
assy pics and scaled using the cobra aluminum paddles, bending was hit and miss, went through three sets before I got it right.
Used the total compression length on the master cylinders to set ratio. hope this helps.........

Oh yeah, without the introduction of Tilton's new 'compact remote master cylinders', it would not have been possible.......
