Inputs on a home built 318 for red light to red light fun

Sounds like a good solid old school combo. I like it. IMO no need for stupid RPM. I think 6500 would be plenty enough to get the job done. But as mentioned, for red light to red light fun it's gonna need some short gears. I would consider 3.91 to be a starting point, and be thinking about 4.10 or even 4.30. Generally speaking red light to red light is "somewhere" in the 1/8 mile range. But it will be a REALLY fun car to drive around town in.
I see what you mean as you said yeah 8k plus is over kill I just want to be sure to hold gears long but still be able to catch all 4 in the distance I was thinking hard on the d/dart gears which were 4.86 but to find them are hard can find anyone that makes them I live in the small town of carlisle pa home of the carlisle chrysler nationals and block crusing was huge here in the 80s and 90s and I heard story's of my dad talk of there was always a guy that would come into town cruise the block and be the man to beat and it would change like the John Milner of real life but driving something around and get the feeling and vibe qould just be amazing for me I'm all about the old 50s and 60s style everything it's a huge part of me so I try to keep everything car wise to what they would have built or how they did it to those eras
