400 low-deck stroker...why?

[elacruze]

I've read a bit but not a lot about building 451" or larger B block strokers. What's the advantage? I'm asking because an inexpensive running 400 just fell in my lap.
I know the bore size is bigger.
I know the block is lighter, pistons can be shorter, main cap webs are thicker.
I could use RB manifolds with raised-port heads too...

I guess I've answered my own questions, lol.

Discuss?

Yep, pretty much answered your own questions.

But, I'll add the Cylinder wall strength as well.
NOT, that they are any thicker than an RB 440, pretty much the same.
Just,
that they are "shorter" given the shorter deck height, so lees distance to straddle, therefore stronger.

someone mentioned "better" bobweight... could someone explain what and why this is?

I guess they refer to "lighter" as "better", less parasitic weight to spool up.

Even a 451 removes "1 full Pound" off each Piston weight compared to a standard 440.
That certainly reduces the Reciprocating Factor dramatically.

At what RPM can I worry about the main caps, or are their limits strictly HP related?
