I have a 1995 S Blazer 4x4 with a bad motor. It is a W code motor. The truck has only 36000 miles on it, but it was run with a cracked oil line & ruined the motor. I want to put in a used motor, but would like to know what years & models will be an easy bolt in. I found a 95 4.3 from a two wheel drive Blazer, will that fit?

Thanks
