Cylinder Head Choice

I think nitrous would be cheating for what I’m trying to do. At this point I’m down to go the impractical, expensive route and naturally aspirate!
Nothing wrong with that, just makes the goal allot harder and allot more expensive with a street car. As 318 suggested more cubes will help, or you need a 7k 318 with 4.56 to 4.88 gears and depending on you're definition of streetability it may not be much fun. One thing for sure, it won't drive like a hellcat!.
