What the FE needs for the next stage of it's resurgence is a moderately priced, always available, good quality aftermarket iron 427 block.   NOTHING ELSE will have as much impact.   The block is the keystone of a build, and a 4.23+" bore in a strong block is what people need to make powerful and competitive engines.  
Edelbrock lit the first stage with their aluminum FE heads a couple of decades ago.  A good, reasonably priced, aftermarket iron block, would blast the FE into the stratosphere and keep it going for a long time to come.   I'm not sure what reasonably priced means.  It will still cost significantly more than SBC and SBF aftermarket blocks.  Maybe $3200-$3400 and consistently available?  Made in the USA is a plus, too. 
I know Jay and you guys outlined how hard it might be to make that come true in terms of initial investment and total sales.  I can't do it.  But hell, there are aftermarket Buick and Oldsmobile blocks for heavens sakes!   There's got to be somebody that can do it with the FE?
