Looks Great so far Don, more about the body!
Did ya catch some big fish?

Do you have pics of the alt mount?
Will you run an exhaust pipe under the oil pan?------------------

Don is one of the few that have gone where others on this forum haven't- in the 11's in the 1/4 mile. Rather than trying to criticise his achievement, post replys should offer something positive. Trouble is that we have too many immature whiners that aways want to say "my Fiero is better than your Fiero' or " my swap cost less than your swap so you don't know what you are doing " and all kinds of other childish stuff. etc. Don has proved that he can build a fast Fiero and if you want to do it stop the bench racing and start building.
Dons 427 project like Archies LS7 is an insane quality swap for sure but they have shown what they can do. If you can do better just provide proof that you can do better and then your post becomes believable.Otheriwise its pure B.S.
Keep those pics coming Don

Madcurl,I'll try to post more often to keep you from withdrawell problems.
Dennis,thanks for your support,just trying to build something the Fiero community can be proud of,don't know yet how fast it will be,but I will find out.I'd like to get to the LS shootout in Memphis Tenn. on Oct 9th to 12th if I can get it broke in by then.
Now that the body work is done things should move faster now.I still have a little wiring to do on the motor and trans,but I can do that while the body is being painted.I'm using stand alone computers for the engine and transaxle.

If you can make it down here for the shootout, let me know! I would love to get some pictures and video of your car heading down the track. Two cars I built should be going, so I will be there aimlessly wandering around.

Well... I believe in solid mounts because of their principal
Everyone knows, at least I hope, Energy cannot be created or destroyed, only converted. Energy used to compress the rubber or poly mounts is converted, SO, in essence, you lose some power from the poly or rubber mounts. Solids make it so it has to twist the whole car. Problem is that you cannot (I repeat, CANNOT) place ALL solid mounts on an engine and transmission. The engine will twist the chassis, I dont care how well you build it, it will twist it, and if the trannie mount is also solid, at least on longitudinal, it will break the bellhousing off the transmission. Also if you use solid mounts, I can bet it wont be a good car to ride as a daily driver, rattle your bones out all over the place. Can-Am cars used the engines as part of the frame, actually one of my ideas for a Fiero custom frame is having the engine an integral part. Generally speaking, this will make it so 99% of the force produced in the engine gets to the rear wheels. Though it be a miniscule amount that using solids over rubber gives you (probably a fraction of a HP) every hp counts in racing.

So you want that 0.083 HP even if you've got to deal with your cradle cracking? That's a good choice... 
Compliant mounts take a small amount of energy (the compliance of the mount times the distance the powertrain moves on the mount) to compress and then they do not absorb any more energy. However, as you're lifting off the throttle and releasing the load on the mounts, YOU GET THAT ENERGY BACK. Compliant mounts store energy... they don't waste it. Well designed mounts have a low compliance AND only a small amount of motion. The amount of energy stored is tiny.
However, the big boon is that they take the edge off of any shock loading that you apply to the powertrain. It doesn't take much compliance to do this, but it works wonders for component life.
If you're worried about 0.083 HP, there are a HELL of a lot more places where you need to be spending a LOT of money in order to get all the other tenths of ponies that are hiding out around your car. To go to solid mounts in the name of power optimization without ALSO optimizing everything else to the same degree is just ridiculous.
How do I know you haven't optimized everything else to the same degree? You're not running 10's.

Sorry, Don... that post just struck me as being particularly absurd.
I like your work.

Thank you. That alt is different than the stock LS4. It looks easier to mount. I am not sure if I can just change over to an alt like that?
I like what you have done.

That looks like a properly mounted 99+ 3800 alternator.
