ricky,
Alot would depend on what cam and compression you are running, then suspension, the tires, then??? The questions you asked seem alittle to vague to me.
If it were me I'd search the users rides for the et you want and see what the combos are, that would give you a pretty good idea of what you need.
I personally have had the Keith Craft 331 in for quite a few monthes... so far so good. I haven't been to the track or dyno yet so I really can't tell you what it runs or the hp. Check the users rides...
Good Luck
