I had the same result as Cudafied.......twice . I was probably making something around 725 to 750 hp then.

In 2003 I bucked up and bought a new Megablock, Callies crank, aluminum rods, and Wiseco pistons. (I already had 440-1 heads with Jesel rockers)I have many hundreds of runs on these parts and not one single failure yet.

If I had just started with the good parts I would have avoided 2 engine failures, a lot of work, a lot of down time, and been WAY ahead.



I know everyone likes to save a buck but your experienced shows that you don't save in the long run by using stock blocks. They weren't designed for over 600 HP and even with all of the aftermarket band-aids they will fail at some point.
