I know nothng is with a fiero is perfect but jesus man I just need a little help LOL and I am willing to learn. Do you have time to stop by and take a look. I have been told by a few members here that you are the man in Houston when it comes to the fiero and a 4.9. So what do you think?

I found out how to stop the "Sail On" problem in a thread from April 2004. It starts with the problem , then all of the parts that were replaced that did not cure the "ill's". Then some found a service notice from Cadillac that describes how to stop it. read the whole thread, it's not that long. I saved this one in my favorites.
You know the more I get into this car, the more I realize that this is going to turn into a "REBUILD" thread. I just dont have the time to get into this. Anyone in the houston area looking to make some cash and get this thing to where I need it. PM me please. I didn't know I was buying a project car. I thought it was pretty much done......
Sell the 4.9 setup out of it as is, add some money to that then send the car my way. You will get back a nice 3800/65E install that will put the performance and looks of the 4.9 to shame.
Wish I knew more about the 4.9 to be able to help you out but I chose the 3800SC as a my swap and that is what I have learned about.
I used the camaro tention on my setup. The bracket I made was very simple. Probably one of the simplest I have seen yet. Here is a direct link to the portion of my rebuild where I built it. Hope it is somewhat helpful... https://www.fiero.nl/forum/A...-2-082515-2.html#p44 If you need larger pics I can e-mail them to you. I never got back to resize the pics before the thread was archived.
EDIT: I have an extra tentioner bracket that I made when I thought I had a belt chirp. The problem ended being a bearing inside the alternator so I had no need for the extra bracket I made. If I can find it you can have it.

We after pulling off the wire harness and reconnecting every single wire back to the motor, I have solved some problems i was having. The car is running very good now. Not running rich at all. I still am having problems with the temp gauge working. I have no idea how to fix it at this point. I think my pully set up is all wrong. After looking at a few other setups on here, I think mine is prob over kill and a pully was added that was not needed. Ill post a pic later.

Is funny how when you get into a car (working on it) how you find so much wrong even thought it looked good. I have been fixing things on this car day by day. I spend an hour or two each day on it and I have come along way in the last month. I got the car and it had a number of upgrades (brakes, motor and other things) and had no real info on what was done. I am going to try to find out what calipers and rotors is on the car. It is not the stock set up but I have no idea what it is. The temp sensor thing is driving me crazy as is the extra pully set up... The heater doesnt work, no fan when you turn on the switches, the wipers do not work at all.
I also need to find a few things. Headlight switch, driver side headlight system. Driver and pass seats. Third brake light and the lst goes on and on....
Well we will see how it turns out.
IF anyone could lend a few words of advice I would gladly take it on all I have wrote so far.

Can I bypass the inline fill or does it have to be there. I have read a lot of build threads but nothing really covers this. Its really ugly as hell.
no - since the engine sits high thatn the rad you need a way to get the air out that would be trapped in that location. You don't have to use an inline on, you can also modify the thermostat housing to a similar ideal like the Fiero has.
You need to have a fill connection in the engine compartment. Either the in-line set-up you have or a modifed Fiero fill connection (aka thermostat housing).
What you don't want is that small line that comes off the in-line fill connection neck. That connection should be plugged so that all breathing of the coolant system occurs at the radiator cap.

So I am confused, can I remove it or I need to have it?
You need a way so that you can fill the system with coolant and help remove any air from the system.
Use the inline method or my way, I cut the top bit off the housing from a 2.5l Fiero and 4.9 housings weld them together:
As Sanderson pointed out, you need to plug the small hole on the inline on (or run it to an overflow botlle that you will have to mount in the engine bay.
So If I were to jack the front end all the way up, Cant i bleed the system that way? I have seen two 4.9 setups that did not have the filler in the stock location.

Try what you want - I am just telling you what works fairly easy from my personal experience (inline or modify the housing). They (the 2 4.9's you saw) may have had another way of letting the trapped air out - I can not comment without seeing them (or pictures) myself - you would have to ask these people yourself.
BTW - jacking the car way up in the front will make it hard to get trapped air out of the heater core (which incedently is also higher than the rad). For some reason, the engineers at Pontiac put one in at the motor when they built the car - had to be for a good reason.

Ok so I got the car on the DYNO tonight after all codes were cleared! I wasnt really wanting to know HP I made but I did want to see what was going at Data Log side. Here is my question. The car is going lean at higher RPM's. Its not the ECM Tune thats for sure. Are you guys sure that the stock V6 fuel pump is ok with this swap. Seems like its not getting enough fuel at high rpms. i am going to swap it out tonight for a TRE-343 (255 LPH) and see what that does. I'm betting it kills the lean condition!

Can't say 100%, but I run mine at the track without any problems.
