I remember something about an alum. 2.8L that someone had, but I can't remember if it was an exact fit or what. Anyway, you may want to try the Forum Search, or just google for "Aluminum 2.8l Fiero"
There was aluminum Bow Tie (made for motorsports) block with cast iron liners in the GMPP catalog back in the day. They pop up on ebay and racing classifieds every now and then. These can handle 700+ HP when turbo'd.
There were a very few prototype production aluminum blocks made. They were linerless and made of hypereutectic aluminum. They had a bolt in lifter bore carrier like the 4.9. A few of them surfaced when GM was going through its bankruptcy proceedings, but I've only heard of 2 or 3 making it out into the world. Don't expect these to be any stronger than the regular production iron blocks.

It's a clone of the pre-3800 3.8 block, so I think it's the BOP pattern, though it might be the big Chevy V8 pattern, given their target is race applications.
(The metric pattern of the 60 degree V6 is used in both FWD and RWD applications.)
depends on your definition of "straight bolt on". you have to use the gen 2 or 3 intakes as well, Gen 2 may be able to use stock exhaust manifold, not sure, gen 3 would require re-working the exhaust. after that the only big thing I can think of is a tune.
Edit: I forgot about compression ratio, this combo makes the compression ratio very high(not bad for a race application)

The TA block uses dual patterns for BOP or Chevy corporate large bellhousing.

Well, I know the Firebird had a RWD 5 speed in that pattern for the 2.8 but I don't recall anything else.
Edit: I forgot about compression ratio, this combo either makes the compression ratio very high (not bad for a race application) or very low. I forget which, but I'm pretty sure it goes way up.
Changing pistons for a head swap... minor detail, eh?
Well, they got the 2.2, 2.5, and 2.8, for engines with the metric bell pattern. The F-body did get the 3800 though. Point was that F-body and S-trucks both were RWD and had metric bell pattern engines, not that both came with all the listed engines at some point.

I'd be less worried about the compression ratio, and more worried that the pistons and valves will collide, given the change in valve angle and the use of dished pistons in the gen II engines. If you don't change the pistons and slap on the gen II heads, you'll probably find yourself needing a bunch of new things very quickly.

it's been done before without problems, doesn't mean it can't happen though.
If we go back in history GM developed an all aluminum block V6 engine that was used in the Oldsmobile Cutlass & Jetfire. This had to be back in the 1960's. The engine was not a success and was sold to British Leyland or it might have been Land Rover. Eventually the engine came back to the states became the 3.1L and was made in cast iron. So to answer the question 60* v6 engines were made in aluminum but why would you want one when better engines are available?.

completely different engine designs, you're a moron.

I think you're confusing a few engines with each other. First of all, the 215 V8 (aluminum block and heads) was sold to the Rover Group. The Fireball V6 was not. Also, the Fireball V6 was based on the 215 V8, but had an iron engine block. And it's the ancestor to the Buick 90-degree V6 engines (3.8, 3300, 3800), not the 60-degree V6. The 60-degree V6 (2.8, 3.1, 3.4, 3100, 3400, 3500, etc) is a completely different engine family... a clean-sheet design from Chevy.
Also, the aluminum "bowtie" blocks for the 2.8 V6 were made specifically for motorsports. AFAIK, it was never offered in a production vehicle.
