250-6 in a Blazer?

Anyone ever had or driven a Blazer with a 250-6? I bought a '76 Blazer without an engine and have access to a new 250. It is currently fulltime 4WD, new turbo 350, has 373 gears in Dana 44 and 12bolt axles and has 29x10.50 tires. I don't want to go to the trouble of exhaust and installing the engine only to find that it is a pig that won't go anywhere. My goal is to drive it as a daily driver with an occasional weekend of light bouncing around. Will I be able to cruise at highway speed without having my foot mashed to the floor all the time? What kind of mileage do you think I can expect out of it? Any advice or experiences you are willing to share would be much appreciated!!

<font color=green>I think that you'd be happier if you held out for a 350. They're a dime a dozen and make a whole lot more power than a 250.

They're torque engines. You won't go fast, you won't accelerate very fast, and honestly, you won't get very good gas mileage. On the trail or towing, they are great because the torque is always there and available down low.

For what you described, Sandman is right, get a 350. Parts are super cheap, they are a dime a dozen, much more power potential, speed parts are cheaper and much more common, and for the uses you describe, a 350 would be much more suitable for it.

Re: 250-6 in a Blazer?

I recently rebuilt and stuffed a 250-6 in my 86 3/4 pickup, for the sole point of proving to everyone that a 250 with the right gears will perform as well as a 350. Everyone laughed at me and said I'm wasting my time. Let me give you my impressions and time proven facts: 250's produce lots of low end power. They get ever so slightly better gas mileage than a 350, but not much. Parts for a 250 are equally as cheap as the 350, just not well known. Any NAPA store can get any part for the 250, just as cheap as the parts for a 350. I put an Edelbrock 500cfm carb on an Offy intake. It still needs a little timing work, but I think it'll be OK. If I were to do it again, I would stick with a 2-bbl intake and carb to get a little better mileage and a little better bottom end. CFM doesn't build power. I have a 4-speed and 4.10's. Overall, the 250 is simple, and easy to work on. It doesnt' have much room for accessories though. It's a good motor, and fun to work on, it's just different and not what everyone is used to working on.
