Does anyone know if there is any truth to this claim?
3946074 Heads on Ebay
If there is truth to it, I am curious why GM would do it. The L89 was the L71 435HP tripower engine with aluminum heads. If they went to open chamber they would have to design a specific piston for the L89 427 application and make specific shortblocks for that application as well.
Any ideas?
Thanks,
Jason
