Hi Guys,
I am currently rebuilding a Chevy 350 SB.
I am having problems with the crank not turning after installation of conrod shell bearings.

This is abit of background:
The pistons are hypertech with groove to front of engine.
All pistons are in the correct bore and all ends and rods are matching.
End caps are torqued to 45 ft-lbs and assemble lube used.
I can turn engine over when I torque each end cap seperatly.
Can turn engine when more than 2 or 3 end caps are torqued.

Please any ideas.

Thanks,
Mike

Welcome to the forum.

Did you check the bearing clearances?

Might post over in the General Tech section to get more views.
