Any 10 second "All Throttle" 318's in door cars ?
At some point you should figure out which parts that you have laying around are going to play well together. Personally I don't like to see an extreme mismatched combination.
I know you don't have any ET goals but choosing the best combination from the parts you have or are willing to acquire could be a good goal to set. I suspect this is what you are already going to do. If you are considering a re-ground hydraulic roller cam this will probably be the rpm limiting component in your build. Once you know the rpm limit you can choose the rest of your combination to compliment that rpm range.
I have seen motors on my dyno that never get to peak horsepower because they float out (hydraulic rollers) or don't have the bottom end to support the rpms needed to get there. Personally I sometimes feel disappointed when I see that but my customers most of the time are not. They are usually stoked just to see it run.
