The Fiero 2.8 V6 does not have provisions for a crank sensor. It does not matter if variants of the 2.8 were used with aluminum heads on blocks that had crank sensor provision or not, its irrelevant. :sigh:
If you think it easy to use an MSD crank trigger to control a GM DIS system, then by all means, spend the $230 and ave at it

I'm failing to see why you consider it irrelevant that DIS 2.8 blocks can be easily found. If I wanted to build a DIS 2.8, I'd start with that block. It's not irrelevant at all.

I agree that the best engines are not built by the factory. However, if I'm going to the trouble of building an engine, I'm going to use the best and most tunable ignition and computer that are readily available. That means DIS to me. DIS is also not that much more expensive and is easier to set up on an engine that originally came with it than moving worlds to install a distributor with an intake never meant for it.
Don't forget that swapped engines can also be built, and getting the best results from turbo or N2O also involves building an engine.

Irrelevant since the original subject of this post was installing aluminum heads on an existing "Fiero" 2.8 V6. If a swap to a different pushrod 60V6 block is solution at all, then a late model GEN III block would be the obvious choice. No offense intended of course, just different logic involved.
I converted a Lumina Alum head 3.1 to a Fiero iron head 3.1. Went with the simple swap. I still have my old blown 2.8 shortblock, and the Gen 1 alum heads. I often think about putting them together, and modifying the intake manifold & plenums to use Fiero sensors, so I can continue to use my existing ECM. Havent thought much about the distributer clearance problem. or the re-locating the dogbone. But, it is something I want to do. and now, thinking about the 3400, with roller cam & even bigger intake ports would be even better. but, at that point its turning into a full swap, so the 3.4 DOHC seems the better way to go at that point. anyways, the whole problem is lack of intakes to chose from. you have 3 choices - iron head stock, iron head carb, alum head stock. thats it. to me, thats where you start. pick one of them 3, and deal with the problems of that setup.
