Could re-cast our blocks in something way lighter,
I had the luck and joy of driving an eagle e-type recently, this is exactly what they did and recast the jag straight six in aluminium... but it does cost a million squid!
Am I being stupid hear?! But if you want an aluminium block dose a m54 not have near identical engine architecture? They are dirt cheap £500 for a good one! That’s what I would be looking at?!
I have no idea about the specific differences between the two but you'd have to ask the question why did bmw give their M model a heavy iron block vs the (I imagine) similar aluminium block they had to hand. Remember this engine spins up to 8K with a long stroke ergo piston speed is extremely high, cylinders are 4 mm apart or something like that on this 3.2 litre and aluminium at the time was imo not cost effective to produce in the quality needed. The mclaren v12 famously consisting of "2 m3 engines stuck together" did have an ali block but then, oh yep, it cost a s**t load of money too.
All that said I'd imagine someone's probably tried it out there somewhere
