Are you wanting fun 100% on the street only, 50/50 fun on the street and strip, or 20/80 on the street and strip?
Hey Turk. To state, 500cfm carbs are on tons of 318s, are cheap and plentiful, and work fine for a myriad of 318ci set ups even on small valve engines.
Also, torque is the proper measurement that does get a car moving. Horsepower is a calculation of torque and engine RPM and how fast it get to those two numbers is the corresponding horsepower number.
Personal experience says to me a fun car is not a 3,000 stall and are firmly in the performance oriented only category as they are often a pain on the street for driving any real length of time. If Dan-the-man likes to "Punch it!" occasionally then the 2,200-2,500 is fine and his engine build thinking is okay.
