So now that I've decied to convert my LT1 front end to an LS1 front end, I've been thinking a lot about making it a front breather.

Why don't more people do it? Seems like a little trimming of the Impact foam and bumper beam and you could duct air directly to the radiator instead of scooping it from the bottom. The openings in the bumper are about 70 sq inches combined. Seems like it would be plenty for the radiator.

Seems like it would be a more efficient design and create less lift at speed.

For those who have done it, how does it preform?

Works great on a race car with an air dam that would not be streetable with the dam in place. The bottom breather has its own air dam with that deflector, and it works on the street because it is close to the front spindle centerlines.

Is the bolded above pertaining to the down force and stability at speed of the stock deflector/bottom breather set up, or ONLY about the airflow cooling ability (and WHY, if the latter)? (IMG:http://www.frrax.com/rrforum/style_emoticons/default/gr_confused.gif)

I was addressing ground clearance needed for street use vs race use - the closer the air dam/deflector is to the spindle centerline, the lower the dam can be without scraping, for a given grade change.
