Ok, put in a new long block and had the tranny rebuilt. Has mild cam and flat top pistons. While trying to turn it to TDC, I flat out can't, and when I say can't, I mean to the point of flexing a 1/2 Inch breaker bar with a cheater pipe on the end. Plugs are out and Dizzy is out. Any ideas on where to start? had tranny in N and diff and N and every other tranny combo and yes I topped it off with fluids. It is a C4.
Thanks
