I had taken apart my motor due to a faulty aftermarket higher lift cam. Put a stock cam back in, filled everything up and tried to fire it up. First time, I could tell it was out of time. No big deal, got in a hurry and had distributor installed 180 out. Put distributor back in and tried again. Cranks over fine like everything is okay anf then it starts to slow down, almost like something is binding.

Starter checks out good
Battery power is good
Timing is dead on at TDC
I am getting fuel
I am getting spark

I am at a loss. I have had jeep motors apart a thousand times it seems like and I have never had this problem. Any suggestions?

Thanks
