You mean with retarded timing right? Banks sells twin turbo SBC crate motors that put out over 1000hp non-intercooled. And they claim about 600hp on pump gas, with a stock 350. And I've seen alot of non-intercooled Buicks that run in the 10s. It can be done, but it'll really help too keep your motor from takin a ---- on you.
