Chevy 350 Small-Block Carb To TBI Conversion - Modern Improvement

With the engine set to TDC (top dead center) the non-computer-controlled HEI-type distributor was removed by undoing the pinch-clamp at the distributor's base.

Before proceeding any further, the hole for the distributor and the TBI were covered so no foreign objects could fall into the engine.

The stock mechanical fuel pump was removed and the hole covered with a block-off plate (included) and the stock fuel line was reconnected with a fuel line from the electric fuel pump, and joined to the TBI at the top (after this photo was taken).

The computer-controlled distributor from the kit was installed and timed at 10 degrees BTDC. Notice more white-tagged connections have been made as the wiring harness is positioned into place.

If care was taken to fit the wiring harness properly, everything will appear cleanly routed such as these coolant sensor and knock sensor connections. After installing a new air cleaner to fit the TBI, the '75 was ready to fire up.
