I don't want a 4" crank , If I stay 340 I will use the stock stroke. I like to rev and my car is a 4 speed so cam choice isn't really a problem and I have 4.56s so a tourque stroker that is done at 6k isn't in my list of goodies. Every car I see now has a stroker , I'm old school. I like to rev , Make a buzz saw that rips. Might not be fast but I guarantee that it will be impressive for what it is. I have a stock bore 340 block that I might work with but I'm really thinking about a 273. Confused at the moment.
