Is there a difference between the 4x4 and the 2x4 motor mounts or are they both the same?

RedXray

The frame mounts are different on GMT800's

Little_Mata

Thank you for the reply. I understand the frame mounts are different however I am wondering if the motor mounts that connect to the block are different from a 4x4 and a 2x4

the actual motor mounts Should be the same.

RedXray

Yep...

I'd stay away from aftermarket motor mounts (like Anchor) as some headers brands (like Speed Engineering) have clearance issues because the aftermarket mounts tend to sag a bit right out of the box.

I did a swap on my 2003 Silverado. Did everything mentioned on this post. But my rpms are crazy. 3k on 60mph. Left the v6 tranny with the 5.3 flex plate. Was reading something about a spacer needed. Any help ?

RedXray

No spacer needed. You may have a shifter cable issue but it sounds like the trans cant find 4th gear. Count the shifts to make sure you're in overdrive. The V8 crankshaft will turn the same RPM's as the V6 if the rear gear ratio is the same. Make sure the tow/haul button on the shifter is not activated either.

Anyone have pictures of their fuel line set up?
Finishing up a 5.3 5 speed and this is my last thing to do.
