Not sure, any suggestions? Gas milage is the reason for this conversion to begin with. Also the 5.3 Engine is a Flexfuel vehicle.

I will be needing some economical suggestions for headers, fuel tank/pump, tranny cooler, motor mounts, cam, and electric fans. So, If anyone has made this swap and has some suggestions please let me know.

Thanks,
