Engine Install Problem!

I can't get the engine to go all the away against the transmission. I have floor jack under the transmission, the engine is still hooked to the lift and have a hoist adjustment to raise the motor (don't really know what you call it but it's the blue thing in th picture).

I have tried everything far as letting the jack down and up also lifting the motor up with the motor lift and adjusting the hoist thing to level the motor or unleveled the motor. It just will not slide all the way on the transmission (4-speed) I get to the point of almost sliding on the splines of the transmission but that's about it. It likes just a little bit to get meshed up together. I tried installing some bolts to try to pull it together but it feels like it gets it in a bind. It's like the transmission shaft is to long hitting the crank therefore not letting it go all the way in to bolt it up.

I installed a new pilot bushing,throw out bearing, clutch, fly wheel resurfaced. My friend and I gave up tonight because we were both tired.

Any suggestions?? Something I'm over looking?
