For starters:

Vehicle Hood Clearance ...?

Weight ...?

Gearing ...?

Type usage 80% of the time ...?

dont have a car/truck to put it in yet building the motor first but in the end it will go in a late 60's f100 or mid 50 sedan 80% of the time will be just cruising around town running to the track every once in a while

The hood-line of the vehicle will determine the maximum height of whatever intake manifold; the best manifold for the application, (Trick Flow "Track Heat"), is usually to tall for a regular car.

EVERYTHING should be determined by the particular vehicle and how it is going to be used.
