I am glad to see another Quad4 Fiero in progress. It was a fun little FWD engine that loved to rev. I started down the road of building a Quad4 Fiero, but the project got derailed when my Quad4 block was un-usable.
I may have some odds and ends you could use. I have the W41 EFI chip that is supposed to be good for 5hp over the H.O chip. I also have some rebuild parts that you may need too. Send me a PM if you are interested.

TOO AWESOME!
Just an FYI though, the throttle body is off a shortstar not a 3.4 DOHC, I've got two of those TB's in my garage.
What are your plans for the swap, just a rebuild? or maybe on of those fancy spinning exhaust things that go woosh?------------------
there's a Group on 60degreeV6.com for us 660 Fiero owners!

I know these lines Look crooked on paper, but I swear I've got them straight in my head.

The chip I have is allready a W41. I think I have what I need, and I hope to have this swap done by the time anything could arrive in the mail. But I will PM you to see what you got.

Mainly just a rebuild, and getting all the power I can N/A with what I have to work with.
I allready have a "Vacuum drivin centrifugal exhaust muffling device" on my GT and with that, I know boost makes my MPG damn near go in the negitives, (can't stay out of it, too much fun) and stock compression being 10:1 doesn't give me any room for boost. And I just don't want to boost this swap.
I was also told the TB is a 96-97 3.4 DOHC Throttlebody.[This message has been edited by sardonyx247 (edited 06-20-2012).]

Definitely a 3.4 DOHC TB. But, it looks like they are pretty much the same anyway. Keep up the good work, I'd love to see this back on the road.

Time for more pics.
The cam towers.
The bottom end. Well the stock windage tray anyway and oil pickup.
The cast aluminum oil pan. mmm milky oil.
The combustion chambers. Unfortunately this head is cracked so I can't use it. So time to tear down another Quad.

Quad number 2.
There are some brackets/heat sheilds/etc that were missing from the first Quad, so this engine will "fill in some blanks"
Hopefully this head will not be cracked.

The missing brackets.
The heat sheild on top of the exhaust.
The front engine lift bracket.
The intake support bracket and transmission lower cover.
The lower exhaust manifold bracket.
The rear A/C bracket.
The front A/C bracket, small but still a bracket.

Curios about the milky oil, that one is a surprise. The CC's look free of leakage, you would have seen a clean piston. I wouldn't put too much weight into minor cracks between valve seats and spark plug holes. That head may still be the best one you'll find, unless of course the milky oil was the result of a more serious crack in the head. If you have pictures of the cracks I'd like to see them. It took me quite a while to find a head that was, at least at the time, free of cracks. It came from a 91 Q4 LO. IIRC. Not like there isn't a whole lot of these in a yard very close to you 
The only places I could see being the source of the leakage would be either a serious cracked head, water pump, headbolts, a leaky headgasket, or water getting in externally. Either way I'm still a bit surprised that it has milky oil.

Yes the cracks are very small, don't know if they would show up in a pic. But they are there none the less. As far as using the cracked head "Just say no to crack"
And picked-a-part wants close to $90 for a DOHC head and they are not the easiest to pull. The milky oil is what was left over in the pan, I don't recall the oil being too bad as I drained it. As for seeing the cracks you are encouraged to come see them in person.

Tear down of Quad no.2
Full of water, poor engine.
And the DIRTY head.
BUT it is crack free, it is not an 086 head but it is a 753E head rated at 5 less HP, (non ported) and less prone to cracking.
The exhaust ports are a little smaller, intake is the exact same and valve sizes are the same too.
Took a few hours cleaning out all the carbon from it, and the valves don't look so hot.
I need to figure out what all to use head wise at this point.
More to come.
