    Callies has some really good cranks and rods, the pistons if you are looking at 12.5 to 1 available, but any different compression and have to be custom built. Their phone number is 419-435-2711

    I used Eagle Crank and Rods with L19 bolts with JE 13.2 pistons, i also used bearing spacers on the mains. The whole unit including balancing cost about $1700.00, but there are better rotating assy's out there. I have turned mine to 8,000rpm and it has run 5.15, 1/8 times and 8.23 @ 158 in a dragster, never used nitrous though.
