Sal, for better or worse, was THE Marvel house style in the 1970s. Dude cranked out 3 books a month! Of course, they were all stock poses and the same 5 facial expressions, but hey they were easy to read.
Makes Kirby's output in the 1960s even more astounding, because Jack never relied on formula.
I had the crazy luck that in one of the few stories I drew for Marvel, Sal inked it and I got to talk to him over the phone. He told me he never really wanted to pencil but Stan kept bugging him to, he was happier inking.
