4 banger

[rustyrodknocker]

Hi guys I have been thinking about a s10 lately. Started looking for a v8 blazer.then thought about a 4.3 for some decent mileage. So that got me thinking about the 4cyl. I dont know what they are or anything sbout them. Someone on here called it an iron duke. Are they actually an iron duke? That would definetly get my attention. I have always wanted one. I am at a total lack if knowledge on these small rigs. Thanks for any feedback.
