I live in New Mexico so that does not give you a lot of places to go in the winter time . does any one know how fast the car should run at sea level. the way it came from the build center. I was just wondering what to expect. I know i will have to change up tune ups as i go. Thanks

Randy, depends on class you intend to run ( weight ). Car at FS/B weight
from the factory, my estimate would be .4-.5 under index. But you will
need to get a good tune on Holley. Welcome to the world of COPO racing.
