ok street port just opens up the port that is already there. but since this changes the time at which it starts to open and close this also changes that.Bridge ports are so big the go past where the seals ride on the side plates so a "bridge" is left so they don't fall out, hang up on the port. Street port range from mild to WTF! big. Most are streetable. Brigde port is a little to much for a street car. As with the bridge you can have small to big but where the bridge starts at is on the too big side of street ports.
Street Port=little head work and mild cams in a piston car
Bridge Port=a hogged out head with a fat *** cam
