Ok, one of my friends has a 455 buick...I know the buick motors are tough but my question is...are they rather expensive to build or would it be like building a chevy? I am craving a big block in my el camino, and im not predjudice as long as it's a GM. Anyone having some good suggestions would be very much appreciated....

Also, if anyone has a good look at big and small block build ups i would appreciate if i could get them. Thanks!
