With the supply of Magnum blocks out there in yards, I'd guess it'll be another decade before there is a business case the aftermarket can make work.
Who knows, by that time us small block guys may largely have gone Gen III leaving a tinier space for aftermarket LA blocks.
Comparing a magnum block to a race block is like comparing an anchor to a pillow. It's rediculous.
personally I think it's more like comparing a cast iron block to a plastic mock up block..
As much as I like the G3 Hemi, reality is if there was availability of new race blocks at a competitive price to the Factory BGE block, the small block is going to be the 1st choice for a max effort build.
it's narrow, more after market parts, Cams , rocker systems more used aftermarket parts. better header to chassis fit. Weight is about the same as the G3 but lets face it there are more proven combinations for the SBM.
