A big block is a low compression engie anyways. Now you talk about squirrely, if it was not for my trim tabs, I would be in dire straights. She fast but thristy. No a do have a Rochester 4-barrel on the engine. Very small primarys but monster secondaries. As long as I keep those closed, I get about the same milage as the 305 and 350. Torque moves mass....Dirk
