Eric Hinderberger at PE built my 351 (418) stroker in February 2004. I was impressed by the flywheel dyno #s. 567hp / 554tq.

The engine ran flawlessly on the street, road courses and drag strip for 46,000 miles until I blew a hole in a piston at the drag strip in August 2009. I had Eric repair the damage done (new pistons, valve springs, etc).

Unfortunately only 4000 miles (and a few trips to the drag strip) after the "rebuild" I discovered that 10 of my push-rods were bent. The local mechanic stated that the cause of the bent rods was spring bind due to the wrong springs being used. Eric maintains that the springs were the correct ones (even though he was unable to provide me with the brand and part # of the springs).

We are currently awaiting a review of the springs by Comp Cams.
