SB or BB a body debate

I must of missed it but want car are you running that you can get BB headers for?
I find it funny most people on these forums tell you don't run a 273/318 run a 360/408 because there's no replacement for displacement but here it's run the smaller bad bore to stroke and rod ratio engine, get a 440 run stock stroke bottom end dump your money in the top end. You got to put a lot of money into sb short block to get it to 440 CID if you did the same to RB you'll have a 622 CID.
