My engine is on its last leg so I need a replacement. Found this one on craigslist for 600$. Do you think its a good deal? Also, does anyone know how much a 2.8 shortblock weight?
For anyone interested in that transmission, it's not a 5-speed. The cable mounts and levers tell the story, along with the end plate. The Isuzu 5-speed had a yoke that held the cables. The Getrag 5-speed had a metal plate end cap and the 4-speed had the two round castings that used U-shaped metal clips to hold the cables in place. This is a Muncie 4-speed.
If the engine has been fully rebuilt, head to crank, it's a good deal for the long block. Even with that, it would be wise to check torque values on rod and crank journals, and head bolts. And get receipts for the parts and labor.

Ah, so it is. I didn't notice the picture before. He probably ran through all the gear positions by hand with it sitting on the floor, and counted reverse and all 4 speeds together as a 5 speed.
5 speed manual transmission - $400 - New clutch shaft bushing (upgraded common wear part) - Upgraded roller bearing transaxel seals - Inspected, cleaned and painted
Enough said?
It appears that people who swap stock 2.8's struggle to finish more than those swapping 3800 SC's. One of my '85's needs a new engine pretty soon. A 3800 swap makes more and more sense.
My second Fiero came with a swapped transmission and what appears to be a rebuilt 2.8 the PO didn't even mention. Six bills is way too much to pay for who knows what.

I'd be a little leery of buying a "rebuilt" engine as well, especially one you can't hear running.
Who rebuilt it... some guy in his garage or a professional shop? Either way, it's probably going to come with a 30 foot or 30 second guarantee.
If I was in need of a 2.8, I'd try and find a good one that's being swapped out by someone for a bigger/newer engine. I've seen perfectly good 2.8's being given away in this situation.
The motor was rebuilt by a machine shop. Upgraded springs / lifters. New pistons rods. I have paperwork from the machine shop. I looked the machine shop up and they have been in business since 1976. No bbb complaints. Looks like I got a hell of deal if you ask me.
I drove it home (a 2 hour drive) in the passenger seat of my current fiero... LOL
Also came with a new fierostore dogbone. I am happy.
If you're looking to replace the motor... I would just go ahead and get a 3.4 V6/60.
You can get them pretty cheap, and might as well have the benefit of added power.
I'd be more than happy to LOAN you the jig/bracket from Rodney Dickman that I bought that will allow you to drill that extra hole for the starter (that's all you really need to do, other than popping out the freeze plug for the distributor).
So, I ended up buying the engine of course. Sorry I don't have pictures of it in the passenger seat of my fiero. It wasn't technically in the passanger seat, I took the seat out so it was more like sitting on the floor.
Anyways. I was able to get it up onto my engine stand to check it out a bit. The previous owner painted it a horribly ugly blue color which i guess I will sand off. It has a few performace parts.
Magnum roller rockers. Crane springs, New Ross pistons. From what I have read online the rockers will give a higher lift which should gain 15-30 hp buy I don't know if thats true or not. Please answer if you know. Here are some pictures.
So, I put the motor it and noticed it had a really hard time cranking. I couldn't get it started so I sent it to my mechanic so he could inspect the work. He did a compression test and said the first cyl failed. He thinks the timing chain was not installed correctly among other things.
So I have to pull the engine back out of the car now.... Sigh.
I am thinking of just pulling the motor out and having my machinist go through it.
Since the motor has never run, can I reuse the head bolts or do I have to get new ones again?
If you got Ross pistons you got one hell of a deal, my Ross pistons cost me over $700, my magnum roller rockers cost me about $119 barely used on a deal. Now being you have forged pistons you only have one option now, BOOST IT. No debating it, you have to boost it.
Edit to add: You can reuse the head bolts, I have many many times

Damn, this is the risk of buying a never-seen-running rebuilt engine. Hopefully the engine just has some minor, easily rectified issues.
When you say one cylinder failed does that mean it had no compression? Don't you usually have to test multiple cylinders and look for major differences? It sounds like the timing chain might not be lined up right. Not that I've dealt with that particular issue myself, but aside from the time and effort to get in there it might not be that big of a deal.
+1 on the boost. As long as you have to tear into it anyway maybe you should check what you actually have and look for other mistakes. If it checks out boosting would justify your investment of money and time.
Well, he said the first piston he checked had no compression. He said he could check the others but he would charge me a full hour instead of a half... so I just let it be.
I am having it towed back here tomorrow. Won't be able to do much until Wednesday of next week. School and work have me too busy. Hopefully the weather stays as nice as it has been the last few days. Hopefully I can get it out in one day.
When I get it back out of the car, I will have my machinist look at it to verify all the clearances are fine since I don't trust it anymore.
I was going to buy this engine but then I decided I had to at least try to find a 3.4L. The fact the guy said he didn't have the oil pan made me question the whole thing. Let me know what your mechanic finds. He also had a 5 speed getrag for sale as well. What ever happened to his Fiero?
He said he sold the car without the engine. He originally planned on boosting the engine, but school limited his time. I don't know how long the seller was holding on to the engine because the receipt for the engine build is from 2007. I would have questioned the entire rebuild if not for the brand new ross racing pistons and lifters and springs listed on the rebuild receipt.
He said he gave the oil pan to his dad so he could use it for his fiero because his was damaged? The dad was supposed to replace the oil pan; but that never happened.
I wonder if the oil pan story is true because usually the oil pan and timing cover are a set due to the different configurations between years.
The original receipt totals over 3000 for the rebuild. I can't wait to have my machine shop tell me whats wrong. Hopefully its something simple like the timing belt is off. I hope none of the valves were bent in the process of me trying to start the engine
So i had a few hours today. Started a 2pm ended at 10pm. Was able to get whole thing out and ready to go the machine shop tomorrow. Pistons 4 and 6 had this weird orange substance on the spark plugs. I don't know what it was. The motor was really hard to turn over. Even wit all the spark plugs removed. We will have to see what happens.
Ok, so I have yet to take it to the machine shop. My machinist is about 4 weeks from taking on new projects and I don't trust many of the local shops, so i will have to wait.
I decided it was a good idea to take a look at the timing chain and see if it was even lined up right. It doesn't look right at all! Can some verify...
I pulled the heads off while i was at it to inspect the valves to see if they were bent... I cant tell with a naked eye if the are bent or not. is there a test i can do that doesn't involve taking the valves out?
The new ross pistons are flat tops. I have small impressions exhaust valves etched in to the top of them. They are not big, just look like little scratches. I am guessing this is from the timing chain installed incorrectly.
I am now pretty sure this guy lied I purchased it from lied to me. All of the coolant valleys in the block have residue of coolant on their walls, but I never put any coolant in while I was testing. So I think the guy tried to put it in, but it didn't work so he sold it. The engine rebuild receipt is from 2007.... I should have noticed that earlier.
I think If I just get this timing set correctly, I will be fine.
Now for some good news,
I pulled the timing chain off and was able to freely rotate the crank. It feels nice and normal. The cylinder walls have the cross scoring marks of being freshly machined. I think If I can get this timing chain set right, I will be ok to just assemble it back together.

There should be a dot on the crank gear, it needs to be pointing up and matching with the timing gear. The dots need to line up pointing to each other. Take the chain off and rotate the crank so the dot points up and move the cam so its dot points down then reinstall the chain. Fix that then recheck compression.

there are three marks and key slots on the crank gear. I am guessing each key-slot and its corresponding mark are for stock, advanced and retarded timing???
Yeah timing chain is off, undo the cam pulley, turn the crank until the O mark is up, and put the cam pulley back on with the dot down. Then all should be good. this will put the key way around the 11:00 area
BTW I cant make it out in the pics are the rockers 1.52 or 1.6, also with all this work done there might be an after market cam in it too.
You should be able to "rent" (for free) a compression gauge from your local auto parts store, or even buy one , prob less than the 1/2 hr at your mechanic.
BTW, if you don't have one already or don't know, you need an 85-86 oil pan, the 87-88 are different. Just FYI
