As somebody that's not a racer, but is interested in turbocharging, it's helpful to see the side that says, do it right the first time with an aftermarket block, high end rotating assembly etc. However we also need to look at the basics too, which is what was being asked about here.
I also need to know what the limitations are of different types of configurations.
stock block/stock rotating assemblies
stock block/aftermarket rotating assemblies
etc.
What a lot of people forget is not everyone that wants to try hotroding something like this, has 15-20K to spend on just an engine.
My setup is a 455 with an N crank, prepped factory rods, Speed Pro pistons and a set of as cast KRE D ports at around 10.2:1 compression. I "think" this setup could work well with e85 and mild boost in the 8psi range. But if I ask that, instead of talking about the technical aspects of that plausibility, the default for most is just to say don't do it, go spend a lot of money on an aftermarket block, rotating assembly, heads etc.
