I have a 292 ready to drop in. Currently have a 230 (or 250 - can't tell the difference by the casting number). The current 6 banger is all stock but the 292 is tricked with a few goodies - bigger cam, 500 cfm 4 barrel, headers, rebuilt HEI.
When everything is finally tuned I expect a very noticeable increase in torque - both midrange and low end.
