Question about 460 crankshaft

Question

If you have a crank in a 460 that's 1/2 an inch away from the metal at the bottom of the cylinder, how big's the stroke? (in inches)

Answer 1

The stroke is the distance from the highest point to the lowest point the piston travels.  This is set by the crankshaft, not the distance it sits in the block.  You can measure this directly from the crank shaft.  If you have it setting in the block, measure the top of the journal to the bottom of the cylinder as you have -- that's 1/2"?  Rotate the crank 180 degrees and make the same measurement to the bottom (inner side) of the same journal, subtract the first measurement.  That's your stroke.

Answer 2

The 429 is a 385 series and it has a different stroke. but that could still be were the name came from, who knows.

  Do you know it has a stroker in it?  if not, it could very well be stock, leaving room for a 1/2 in stroker.  If the crank is in it, why can't you turn it and measure the stroke?
