aerodynamic drag and body style

[Signman]

Here we go, I run a 3rd Gen Camaro in Stock which sometimes is pretty fast. Built the car from scratch from a street car disassembled pretty much completely then reassembled as a legal stocker with stiff chassis and weight bias advantage etc.

These cars are bottom breathers if you must run a flat hood. Was never in doubt about keeping the air dam under the radiator to keep air flow and pressure in front of the radiator to assure fresh air flow to the throttle body. Use your imagination to take advantage of this with a carb, the fast guys already know. Some advise received from a very experienced racer was to seal up the area from air inlet/grill to the front of radiator area to not allow it's escape from the front of the radiator would help aero, and may help fresh air to the TB/Carb.

Another benefit of running the lower air dam (just my theory) is that it will help speed air flow under the car (along with lowering the body) not having as much getting caught up the open areas under the engine and flowing more smoothly under the trans & floor pan, can't do much about the rear axle area.



Hope this helps.
