More Stroke vs. More Bore
So I thought I would get some opinions from the experts on here. I'm building a 555 BBC this winter for the Chevelle. I true 555 is a 4.560" bore with a 4.25" stroke. However, I don't like the idea of buying a $2,300 block and immediately boring it .060" over. So I'm leaning towards a 4.500" bore with a 4.375" stroke (I know, it's really a 556). This preserves the bore and the longer stroke should make a little extra torque. If it were your motor, which would you opt for?
Also, I can get the 556 short block internally balanced and assembled with the Dart Big M block, Eagle 4340 crank and H-beam rods (with upgraded bolts), JE pistons and Total Seal rings from a shop in Nevada for $4,750 + shipping. I would rather give my money to someone local if anyone knows who might be able to give me a deal.
Thanks in advance for your opinions/advice.
