As far as caddy's go, nothin beats house pulling torque just off idle. Theres prob not a big block stock for stock that can keep up with a caddy motor

That is not exactly true. Pontiac motors looked the same from the outside but there were two series of blocks. Small journal (301, 326, 350, 400) and large journal (321, 389, 455). The 301s of the 80s were also called a "short deck" engine because the deck height was unique. Sorry for the useless trivia.
