Guy claims he has an ultra rare 1 of a kind all aluminum 2.8 six banger. What do you guys think? I know the benefits of this would be lighter weight over the iron block version, but if its the same design then wont it still have crappy flowing heads and whatnot?
he says he can provide proof. someone email him. go 1 of two ways.. either say you represent the largest Fiero forum on the net and would like some documentation and whatnot, just for knowledge and whatnotm or pretend to be interested and say youd like to see proof of his claims, and pics

It's possible but I don't think he really knows what he is talking about - "CYLINDER BORES are aluminum". If they are not sleeved, it would not run very long with the piston rings peeling the aluminum off the cylinder walls! Then when it got hot enough, the pistons would melt into the cylinders. Just my observation anyway.

no, your wrong. They are aluminum bores, Diamoned honed and acid etched to reveal the high silicone contents, which requires the aluminum pistons to be iron coated to prevent PISTON WEAR.
STFU if you dont know what your talking about. I think its clear why I listed on RFT and CL but not here.

Wow. Feel free to go back at any time. Funny how you keep coming back if it's so bad here. Nobody's holding a gun to your head.
I wasn't the one being rude, crude and socially unacceptable. I made a statement, and if I am wrong, that's all he needed to say. Responding like he's an immature jerk is apparently the way he is.

No but you didn't bother to research or follow up on his claim either... that is why I have two edited out posts above. I try not to be 'offended' by people on the internet.

"Aluminum block, yea right bullsh..t, trying to find a sucker"
"Uhh, actually I do have it, it is real, and you're an idiot"
"OMG, this guy was telling the truth, we look so ignorant and we were wrong.. Uhm... GO AWAY! Go find RFT if thats how you want to act and be honest" Some things just crack me up...

yes, chevy made a 2.8 alum block and, there are also alum heads, and not meaning the gen 2/3/4, actual heads, just like our iron heads, cast in alum. Falconer Heads was it?
so - yes - it is 100% possible. and - yes - the gen 2/3/4 alum heads do flow better....

Well, not exactly, it was all Tim petersen and Pontiac, not chevy (they do offer the bowtie block if thats your reference). Falconer heads are cast iron. These came from Central foundries (GM provider) which is now a superfund site.

No gun, they sent me an email with a link. Notice how I didnt post a for sale thread here, I was more than happy away from idiots like you, Pontiackid86 and others who have been registered members longer then when i made the first post about this motor, yet still act like I dont know what I'm selling.

this is classic, so gen 2 heads melt away when the engine reaches operating temperature?

Idiots like me? I was making no claims here, genius. I was just noticing how you were saying that this is why you left before, and RFT is the shizzle and all that, and was just saying feel free to go back there. You have no idea how much or how little experience I have on a Fiero. Please go inhale some more acetone, paintman.

About ten or eleven years ago, I talked to a guy in York, Pa (while cruising the strip) he said that he has a Pontiac Fiero with an aluminum 2.8. It was not there, I never seen the car or motor, and i've actually never seen him again..... He was riding with his buddy in his buddy's car, no Fiero. He seen mine and talked to me for a little. I did not call him a liar right then and there, I took his word for it, and set out to find an aluminum 2.8 in the junkyard (of course, never found one), which let me to find an aluminum head 2.8. I thought I found gold, until I found that the heads had splayed valves, and would not work on a Fiero (atleast with the work that I was willing to put into the 2.8)
P8ntman - was this you? In York, Pa? According to your CL ad, you have the ONLY aluminum 2.8, so if this kid wasnt you, then he must have been lying. I can understand people's attitudes toward something different that they might not have heard of..... because there ARE alot of liars out there!
About the engine.... Is there information online that you have about this motor? Im interested to know more! -Chris

Chevy had aluminum blocks without iron liners on big blocks and in Vegas. The blocks had high silicone content aluminum and required special honing procedures and special pistons and rings. They didn't melt..lol. They didn't last as long as cast iron cylinder walled engines though

Chris, From personal conversations with Tim Petersen (the guy in the picture in the fiero history book) the only way I can have this motor is if it was stolen from GM. I know the owner of the only other block I know of, and the heads are MIA. The prototype Turbo fiero at GM may have this motor, then mine is one of 2 assembled running motors. I'm not the PA guy, and unless I talk to him, I consider him suspicious. Ive had a guy swear to me he had a factory aluminum 3.4 dohc, and we know that was not a factory option the guy was just a moron with the wrong understanding of his motor.
These motors were all crushed, there will be few if any more than mine that are running. In my years of owning it Ive never tracked down another complete.
I have tons of documentation on this. all on RFT. nobody on here seemed to give a **** back when I found it.
Tony, Tim and I discussed the Vegas and how these motors were to save the technology after the previous failure. Unfortunatly these motors were made before the fiero got a large journal crank, and was prone to snapping cranks under boost.

Would anyone mind enlightening me of what the advantages would be other than weight savings? I mean mostly about the aluminum walled cylinders. Thanks.

The vega block was "die cast" at very high presser with the alum/mag/silacone in a "plastic" state. This was to keep the silcone from ending up at the bottom of the mold. the block was hoaned to get the bore serface, than the acid was used to remove a very little bit of the alum so the rings would ride on the very hard silcone. you had to keep the oil clean to make sure you didn't scratch the bore. With no iron liner the motor had very good heat transfer, no liners to leak or come loose. I had a vega, new, in 72. I got about 2 years out of it before the bore went away. Owned failed, not the tech. had it lined. The 928 porch had a engine that used the same tech. The alum block in the vega was to high tech for most of the people that bought them, ( me included )

yes but it doesn't have aluminum cylinders, they are fitted with iron linings.....aluminum would wear too much...

Anyone now what FOAD means??? I think he meant to call me a toad and fat fingered it. I mean I wouldnt expect such a fine example for the community to mean Fock off and DIe, would that really be a nice thing to do??

Fred, thank you for that information. Tim and I never got into the specific mixture of these blocks and what made them so bulletproof compared to the vega blocks, but lets just say that the project iller was the fact that TIm couldnt get the funding to forge crans, and the cast ones were snapping before the bores wore out.
The major advantage of an aluminum block over cast is weight savings. I can lift this block over my head with one hand.
