No Power Slugish 1985 4x4
Is there anything I can do to make my stock 85 Blazer have more power. On the freeway I have the pedal to the metal and I sit there and wait for the thing to get up to speed, it is rediculously slow. I have had the truck for a few months and it is the most slugish car I have ever owned. It is the 2.8 L V6 but come on it is weak. I think the truck has 240,000 miles on it.
Had compression checked at a shop and they said it was fine, but I think they meant all cylinders are about the same, they didn't say what the compression was. What should the compression be anyway? Recently had a tune up done and an oil change. Also had a brand new timing chain put on, but that made no difference.
Is it something with the carb? Vent hoses? Fuel, fuel pump, fuel filters? Exhaust manifold leak?

I used to have an '85 S10 4x4 2.8L and it too was a dog no matter what I did to it. It is the anemic 2.8. Nothing that can be done but toss the engine aside and do a 3.1 or 3.4 swap. You could go all out and get a different transmission for a v8 swap as well, but that isn't as easy as putting a larger 60 degree v6 in.

On the flip side to this I put in a pro-built stock 2.8 in my '86 4x4 about 2 years ago and now have just over 30k kms. on it and it runs just fine. There seems to be ample power, bogs a little on long hills but over-all I'm happy with the outcome. The one thing I wish I had was a 5th. gear. Going 80kph. it seems to be revving pretty high.
