Wouldn't matter if bigger bore has more fiction, up side of displacement through bore size out ways negatives when building power. Why I don't get the 408 trend, i'd even rather build the lowly 383 over a 408.
While there maybe merit to the various ways of looking at this, the bottom line is cubic inch displacement rules the day. Then there’s that vs expense.
I myself like a big bore short stroke engine coupled with the ability to rpm high.
If the cost was the same, I’d do the 408 over the 383.
Between a B vs an LA, the B would be the winner but how does it play out in the car?
Once again, everything is build target dependent.
AKA - What are we doing with what?
