All Small Six 200 rebuild pt2

[kaden_.adams]

Hey! So got my old motor out, few concerns with my new one i just rebuilt. There is this thing going on where the motor won't spin at all, if you sit there and budge it a few times it will start to spin and rotates just fine, and rotates with a 12in 3/8 ratchet, but its the initial start that It doesn't wanna spin. My bearing clearances are absolutely beautiful, been reading maybe it's the green lucas assy lube I used? I went kinda heavier then I should have, and have been reading people have the same problem and it's just because of how thick it is? Also the rod caps were put in from the previous guy in firing order? 1,5,3,6,2,4. Never seen it before but the guy said it ran just fine he just wanted more power in his stang, Any help is appreciated, I have done very few of these old motors and just don't want to put it in and have an issue.

It's your ring tension against the cylinder walls. I know there are specifications for how much torque it takes to start the rotation, but I think if you can rotate it with a 12" long 3/8 drive ratchet then it is fine. The two things that have the most drag of a reciprocating assembly short block are the rings & the rear main seal, especially if it is the old rope type seal. Hopefully another member can pipe in here with the acceptable torque spec range required to start rotation of a good assembly. I usually use an 18" or 24" long 1/2" drive breaker bar to rotate reciprocating assemblies with.

So maybe im just being stupid? I'm confused because I couldn't get it to budge at all last night. It would just turn the crank bolt, so I pulled the rod caps off to see if anything was out of the ordinary, then tourqed everything back down, and it spun just fine, without needed to give it lots of force for it too move.

The crank bolt is correct @ about 135lbs torque. If it's still tightening before the engine turns, needs to be torqued down.
It's rotating now, so good deal!

Small six crank bolt should be 85-100 ft lbs.
