4 banger
 

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.

Here's the quick answer:

http://en.wikipedia.org/wiki/GM_Iron_Duke_engine

and yes, my 1986 s10 has the ironduke tbi: So named because GM did not want it confused with the earlier all aluminum 4 bangers from the 70's....

Tough little engine, I worked in forklift shop where these (or a variation) were standrad in toyota forklifts in the 80's.....


I hope to get myine up and rinning soon-- but from what I hear you can get ~30mpg with one in an s10

I found the wiki right after i posted last night. it stated that many people confuse this engine with the 153. which is exactly what I was doing. Your story about the name reminded me what the point of the name was in the first place.

The four cylinder will get you decent mileage, but it will be pretty lacking in the power department.
The difference a 4.3 will give over an 8 cylinder will be nominal(unless you are talking about a built 8 cylinder).
My wife and I bought a '02 Blazer with the thought milage would be better than a Tahoe. We get about 15-17 MPG out of the Blazer. We should have bought the Tahoe because the extra room would have been worth losing a couple of MPG.
