What is the piston pin dia. on the 383 piston and 413 LY rods, as they don't look the same? And what would be a good size cam for a blower motor lift/ duration? Thanks, I would like to keep the motor cost udder 1200 as I am going to supercharger it for a street rod I am building.

When I imagined this stroker, I certainly didn't imagine it with a blower sitting on top of it! To me it was simply a cheap way to max out an otherwise worthless 413 block. R.
