Stock 340 dyno tests?
Your posts are too long. I see all that verbiage and I'm like nah.
I'm not discounting the merits of an engine dyno. But I also know there's plenty of merit in track testing. PLENTY. Actually, more. Since we race vehicles, not dynos.
Think of it this way. Do we dyno engines so we can build faster cars? Or do we build fast cars so we can then test the engines and get a number? We all know the answer to this.
So many things go into building an actual fast car. The base engine tune you get from a dyno is one of MANY ingredients.
