Best bang for the buck?

I'm not getting involved in that stuff:)
Calcs are not the be all I know, but they worked fine for me for years and are very close to actual time slips until you get into working out stockers and very light cars, then it goes to the wall.
That's why I always talk about Time Slips and proof.. I got to give it to 318willrun I'd like to tell him he has over optimized his car.. especially with his gears.. I do forget he has a 360 and not a 318 though and that is quite a difference... Maybe he'll pop in and remind us what is 318 cars doing now...
