The most direct fit would be a motor out of a "2000 extended cab sls 4.3l sonoma 2wd".I have a 2000 extended cab sls 4.3l sonoma 2wd. Im just curious if anyone knows what 4.3l motor(i.e. vehicle year, make, or model) would be the most direct fit.
I figure as much but i wanted to be 100% before pulling motor appreciate itThe most direct fit would be a motor out of a "2000 extended cab sls 4.3l sonoma 2wd".
Any 96 to 04 4.3 out of a S-series will work. But you'll have to change a few things depending on the year and if it came from a 4wd or not.
Sensors change continually and the bolts went metric around 00-01. Secondary air was added in 99 and EGR was discontinued around 02. Nothing that can't be dealt with, but if you're looking for a plug and play same year and model is best.
