You're a few months too late. I fired it in June. My dad had to move the car after a couple of months of sitting. It fired and ran first crank.
No one's stopping you from doing better. You don't have a piano tied to your leg preventing you from going places.

Do you play the piano too Will.

No, I just play the field. 
I'm 7000 miles away as the ICBM flies, so I'm already going places!

Here are some pics. The car is plastic just like a Fiero so I thought it would be ok for this forum. Hope no one objects.

Totally un-call- for'd.
He is experimenting an working the theoritcal end of engine development. and YES that does involve math and calculations, boring, maybe, but fo the sharper people, there is much to be learned.
He is out of country.
if you read the thread you would know that.
Will and I will disagree alot, but that does not merit any level of disrespect, and that is what I saw in that post by you.
We will get over any disagreement, but we, and no one should disrespect anyone for their direction in engine work.
learn,
cause the day you stop learning you will be in that box 6 feet under. ( my ol man said that all the time, and he never stopped taking things apart and figuring out how they worked)
I wish I had the time to design and select an engine like this. it may not be the most powerful or the best engine to do this with, but he had a desire and he did it. I did that 20 years ago with a 231 buick, and got laughed at, and proved them wrong, so I can recongnize the time and effort put in here.
ok, done off topicing here. Will get home safe and finish this thing.[This message has been edited by tjm4fun (edited 11-29-2009).]

Heh... that'll make some L98 guys want to lynch you. How's the swap going? Any particular reason you picked a '00+ FWD engine?
Are those the CHRF Arias pistons?[This message has been edited by Will (edited 11-30-2009).]

its not really going right now. I mothballed everything about a year ago because I had bought a major fixer upper farm house and between work, kids, and the house there is no time left. I hope to start it back up in about 6 months.
The Pistons are CP, about two years ago I talked to you via this forum and followed your lead. They are 12:1. The block is a 04 with an 04 crank. In 04 some cranks were forged, this one looks forged based on the seem seen in the picture on the rod journal. The balancing guy who did the rods, pistons, rings, writs pins, and crank thought it was a forged crank too. He said the set up we have is the lowest rotational weight for any V8 he had ever seen. in addition this was the last year for the LS1 ECU style crank pick up. I write software for a living and once worked on a product that used the Delphi PCM32U (LS1 ECU), as a side project I re-flashed that ECU with my own boot loader and program code completely erasing the GM software. I plan to use this ECU on this project.
Anyway I am running 05 heads which requires some oil plumbing modes, the heads are almost done with the exception of grinding the height of the valve stems and fly cutting the heads about .020". +00 head had a better valve train with a roller rocker fulcrum, and the exhaust ports are better then any earlier N* year too. Especially since I ported the head. I think I bought the last set of springs from chfab for the 05 heads that they had.
I am also running a dry sump which allowed the nice folks at CP Pistons to sell me some low tension piston rings. The dry sump is about 70% finished. It is s three stage vacuum and 1 stage pressure. I made a dry sump tank out of N* oil tank, which now sites about 2.5 inches less in height.

Interesting. I'd heard they improved the exhaust ports in '05, but I didn't know how much. Do you have flow numbers for your heads? port volumes? What work have you done to them?
What oil system mods are necessary to use the '05 heads on the '04 block?
I hadn't had much interest in the '00+ engines because the '00-'04 had horrible exhaust ports. I had figured I'd skip this generation and go to the VVT engine for my next swap.
I knew that the '00+ had a different reluctor wheel than the '93-'99 engines. Are you saying that the '00+ wheel is the same (or makes the same pulse train from the sensor) as the LS1's use?
Very interesting info on the forged crank. I knew the RWD engines had forged cranks. It would make sense to use the same part in both engines. The Northstar does have a lightweight rotating assembly. The small bore means that the pistons can be lighter than anything for a Chevy. I took 300 grams per cylinder out of the stock bobweight between the Eagle rods and CP Pistons. Did you have your crank balanced conventionally (by drilling holes in the counterweights)?[This message has been edited by Will (edited 12-01-2009).]

I meant as opposed to a '93-'99 engine or a '04+ RWD engine.
