PN: 12363230 $1,735.59 Tired of that tired 2.8 V6 in your S-truck? It's time for a major upgrade, GM Performance Parts style. The HT 3.4 is a bolt in replacement for the 2.8 V6 in your 1982 - 1985 S-10 pickup or Blazer with automatic transmission. And it's emission legal in 49 states (Yes, you guessed it, California said no.) But for the rest of us, the HT 3.4 is the best thing going. With 160 horsepower and 194 Ft. Lbs. of torque your truck will feel better than new, and tow better than ever. The heads have large 1.72" intake and 1.42" exhaust valves and combustion chambers that yield a healthy 9 to 1 compression ratio. The camshaft is a high lift, short duration design, developed to produce lots of strong low end torque and mid range horsepower. With .427" intake and .454" exhaust lift, the cam ensures a strong pull to 5000 RPM. Doesn't sound like your 2.8 V6 at all does it? It isn't, when GM Performance Parts develops an engine we focus on making power. But not power for the sake of power, but power where you need it. For great drivability, towing performance and maybe even a little off road fun. The HT 3.4, a serious upgrade for your favorite little truck. With 40 more horsepower than your 2.8 V6, why would you even consider rebuilding that old 2.8? The induction system, ignition system, exhaust, emission controls, water pump and other parts required to bolt in your new HT 3.4 are already on your truck. Sounds like a weekend project or talk to your GM Performance Parts Authorized Center, they can install it for you. Technical Notes: This is for engines with carburetors only, not released for TBI usage. This engine does not have a clutch boss on the side of the block for standard transmission application.
Note: you have to select a dealer before the site will give you prices. Then click on crate engines and you'll find it.

It will bolt up but you have to move the starter, etc., etc.
Think hard before you pay the extra money over a rebuilt for a GM because when it's used in the Fiero the engine will have NO warranty from GM.

I had my brother-in-law ask a GM zone manager about the warranty issue. (The zone manager is related to the his boss) He says that technically, the mechanical long block can still be under the warranty, (actual parts, rods, pistons, camshaft, etc.) but if its a running issue they will not warranty it due to the fuel injection. (if you use a carb, it doesn't matter which vehicle it's in) I was trying to see if I could help you out, but unless you find an actual part that failed due to defect, it looks like GM is very strict in how they run their warranty.

Ed Parks bought one of these for a customer, at the customer's request. Had very low compression in one cylinder. Problem was found to be caused by out-of-tolerance lifter bores. (I'm guessing they wouldn't let the lifters pump up enough to open the valves. GM said "Improper application. No warranty. See ya'."
Be forewarned.

As I mentioned before, I'm not done with GM yet. As I told the service manager at the dealership, when I tear the engine down, if it's one of those that didn't get the valve seals on it, or the guide/stem clearance is bad, or there's something wrong with the cylinders, etc., then GM will either warrant the parts for that or I'll see them in court.
I'm not a kid, I have the 1) money 2) time 3) desire and 4) attorney to take them on, and I will if I think there's a point to be made.
I've sued GM before and won over a defective AC/Delco oil filter that ruined the bottom end of a Buick LeSabre I owned. They fought like hell when they were dealing with me but once they heard from my attorney and we filed on them, they caved in like a cheap trench.
If they want to void the warranty for injection, fine, then list it that way. Say, point blank "the use of fuel injection on this engine will void the warranty" just like they do for racing applications.
My bet right now is that I have an issue with the heads, but the motor is still coming out even though I *COULD* pull the heads in the car.
With oil consumption at the rate of 1 qt every 130 miles or so, I will find something once the engine's out. Especially since for the first 5,000 miles or so it had virtually no oil consumption.
I looked in my flat rate guide and to r&i the engine, with accesory swap, is about 16 hours. To replace head gaskets is about 14 hours. So I might as well just drop the cradle and avoid all the cursing and swearing.
Regardless, I'm done with GM crate engines. They're overpriced for what they are unless you think you have some kind of warranty and I found out the hard way that you don't, unless you want to take them to court.

That stinks John, I can't believe that is going on with your crate engine! Hopefully you find something out with it and get it back up and running. See ya later.
