Also we liked the idea that it's very likely that the LS7 will be the last engine improvement to the LS series of engines that doesn't involve a blower. So we decided that having the last, biggest & greatest N/A Corvette engine in his car would be unique enough.

That's why I like it... with $4 a gallon gasoline right around the corner here in the US, you are going to be seeing a lot more smaller displacement motors with blowers and turbos. I guess I'm old school where I prefer displacement.
BTW - I own page 33, and when is Troy's car going to be ready to go off to the paint shop?

Troyboy, after the LS7 you will have look up corvette shows and find that pack of corvettes you had a run in with earlier see if they want to play again.

That would be fun , but one guy has a Z06 twin turbo ( he's now my friend because he thinks I'm crazy) . The funny part is that the word is out about the LS7 fiero in that group... I think we have lurkers. But truth be told they are great guy's and have invited me to shows.
Thanks for the photo shop, but Archie would kill me if I make a change at this piont. I'm just going to wait for the new LED fog lights to hit the market and with the small size they can be place anywhere.

We've done a lot of work to The Perfect Union in the last months. Some of it has been covered here and there are still other things to show you. I'll update that stuff later.
Today, it's all about the LSx series of engines in general & the LS7 in particular.
I'm so excited about the Ls series of engines that I can't stand it.
Let me share some of that with you.
All of the LS7 engines are built & test ran by hand at the Wixom Performance Build Center in Wixom, MI by GM & the UAW.
The 1st thing you notice when you look at the engine is the tag on the intake manifold.
Our engine was built by Dale Swenson....
Look at the size of those exhaust ports & the Dry Sump Oil Pan....
When we put any LSx engine in a Fiero we have to make a slight modification to the oil pan & we always turn the intake manifold around.
So we have to take the oil pan & Intake manifold off right away.
Join us for the fun of taking apart a $14000.00 engine.......
One majopr thing that helps when you're turning the intake manifold around is that the bottom of the intake manifold doesn't seal to the valley to keep the oil in the engine. All of the LSx engines have a Valley Cover. Also note in this pic the oil pressure sender mount that sticks up from the Valley cover, we have to modify that to turn the intake around.
that is a work of art..those intake ports and titanium rods are very impressive. looks like the main caps are diamond cut. They are steel ?? Where are you going to put the oil reservoir??

What up with the GBCT? It looked a little dusty last week when I saw it.
Troy,
I did offer Archie my car as the test mule for your LS7. I would love to be there when you guys show up but I don't think Archie and Mark will have my car ready.
I just want to say thank you. I get to sit here and read about a freakin' LS7 being put into a bitchin Fiero (rhymes with Camaro, it works).
I have some work to do in other areas before I can call Archie, and have enough cash to do it. But you know what? It is just awesome to sit here and read this stuff...there is a "Fiero" God. Thank you for laying the groundwork which insures that Fiero lives...and lives well.
The fun thing is what you can see with the pan off....... tell us what you see in these pics.....
I've never seen a dry sump system before but that is not what I thought it looked like. Is it some sort of hybrid system? I thought that there wouldn't be a oil pickup tube at all in the pan but simply a tube connected to the side which sucked the oil out via an external pump.
It looks like there is an oil pump which is inside the crankcase somewhere which picks up the oil and sends it to the reservoir tank?
In any dry sump system you have to have some means to collect the oil and send it to at least one common pickup point; the LS7 pan basically does that. Oil flies off the crank and rods, etc, and runs to the bottom of the pan where it's picked up. Dry-sump systems are also designed to prevent air sucked in from the various pickup points from being pumped through the block, normally the reservoir serves the purpose of separating the oil and air.
Wow, I learned something today... I guess all dry sump systems have at least two oil pumps. One to pump oil from the pan, and another to pump oil to the engine.
TiredGXP: Yes the modification to the valley cover is similar to yours.
We only have to do this mod when we turn the intake around on the LS2, LS3 & LS7.
On the LS1 & LS6 the oil fitting is a lot lower and a simple fitting can be used to turn the OPS away from the intake.
We modified this today (along with the oil pan) & I took them over to be welded.
Was
Now
On the oil pan there are 2 holes just above the Oil filter.....
One is oil out & the other is oil in. On every LS engine I've seen so far GM just puts a cover on those holes (pictured above) that just turns the oil around to go back towards the oil pan. This cover is in the way of the only place we can mount a starter. So we drill a hole inside the oil pan to bypas the need for this cover & then we weld the holes closed. I don't have good pics of this mod on Troy's oil pan today so here are a few pics from my files.
These are from Doc John's car.
We also got a lot of prep done on the new engine cradle & we've got the underside of the chassis almost ready for paint.
