For my spring rate, that F246 would be preferred then? are you familiar with it? Reading through past posts, it seems have to been used in a few builds. No cams off the top of your head that you can throw at me? The machine shop I'm using seemed to have the same feeling on the comp cam, that is why I was hoping someone could give me one or two brands/profiles to look at- I don't mind changing/buying springs to match...
Thanks for input on the carbs- I've felt like the edelbrock is a bit weak, more of a street carb than strip. I've never raced, so this spring will be a new thing for me...
