The TBI 4.3 was called Vortec due to the head design. Torque was 235, not 225, at least for the '94 that I owned. Oil consumption was a little high on that engine but I had no other problems. TBI had a clean, simple look under the hood.

The main reason I bought that Chevy was the Ford 4.9 I test drove was gutless by comparison. Both were 2wd automatic regular cab half tons.
