DESCRIPTION:
This adapter kit is intended for the customer who already has a set of headers in his truck that he wishes to re-use with his new Vortec
engine.
WARNING!!!
Exhaust gas contains carbon monoxide, a deadly invisible gas. Correct any leaks before driving!
1. Attach GM EGR Supply Tube (#10220275) and GM Adapter Fitting (#12552329) to intake manifold
(See Fig. 1)
.
Do not tighten at this time!
2. Attach supplied EGR Supply Fitting to the GM Adapter Fitting
(See Fig. 1)
. Do not tighten.
3. Using one of the Edelbrock bent tubes at a time, position the tubes agains the under side of the fitting and against the side of the header primary
tube. (Use the tube that allows the EGR-supply tube to be positioned in the vehicle so it has adequate clearance around other components). Bent
tubes can be trimmed as needed
(See Fig. 1)
.
4. Once you have selected the tube that fits your application best, remove the Edelbrock
fitting from the EGR-supply tube and weld the fitting to the selected bent tube.
5. Re-install the fitting with the welded on tube and position the tube opening against the
header primary tube, mark the primary tube, remove the header and drill a 1/2” diameter
hole where you have marked.
6. For best fit, re-install the header into position, re-install the fitting onto the EGR-supplied
tube and tack weld.
7. Remove the header and complete the weld.
8. Re-install header with new gaskets and hardware. Tighten the GM adapter fitting into the
welded on tube and fitting, and tighten the fittings on both ends of EGR-supply tube.
