Agree Keith.We always ran the zl-1 cam set up on the square ports and that really wakes them up.The 375 Hp on the street will run fine if you know how to set it up and don't mind setting solid lifters, playing with holleys, changing plugs and adjusting timing pending the gas you can get. Most guys at least when I worked on these engines wanted nothing to do with that vs set up a oval port with the quad and it is good for many miles.
