Pulling slants

I have just done it old school way and many times at that.I have just used the holes on the ends of the head. The front one is where the alternator bracket bolt goes. The hole in the back is in the same location. Just find a couple of bolts in the old jar and thread them in with the chain end on the bolts and tighten them up kind of snug. The engine will balance nicely right to left. You will have to adjust where the chain is lifting to get proper front to rear pitch on the motor. And yes, you can do motor and tranny at the same time. That is the only way I have ever pulled a slant. Good luck!!
