Carb cfm with ported heads?

I live in Texas, most of my driving is 75-80mph, so I'm keeping my "shitty gears".
Actually the car has no trouble lighting up both tires from off idle, it has surprised quite a few people, especially when I tell them what gears are in it.
It's not a race car, it's a really fun street car that I enjoy driving 45 miles to the track, run it four or five times, and drive it home. Some of you might not get it, but half the fun for me is making it run a good number with the 3.23's.

YR- What do you dislike about the Nitto 555R's? I have heard pretty good things about them. What do you prefer instead?

I had customers try them. They have a very narrow tune up window. You can do a lot more with something else.

Also, a bias ply slick is much more forgiving than a radial. Unless you have double adjustable shocks on all 4 corners (and you should) and are willing to spend a bunch of time tuning stay with a bias ply radial.

The Nittos were never "happy". Very small changes in track temp would affect the tire. Just not worth the effort.
