Carb choice for high altitude?

When I lived in Colorado (racing at Bandimere), I used a Holley 650dp on my mild 360 (eddy heads, 509 Mopar cam). I did aProform main body swap on the carburetor to make it a 750dp and the car picked up 3 tenths and 3 MPH right off the bat. It picked up a little more after tuning.

Your article sounds logical from a drivability stand point, but the drag strip results speak for themselves. I would go with a Holley 750dp carb with the HP style main body (no choke horn) for max power potential.....IMHO.

I think i will take the same route you did (start 650 and upgrade to 750 later), my engine currently is not built up as much as yours was it has untouched magnum heads and a small voodoo cam.
