Post flywheel

I have a Big Block 454 tied to a turbo 400 the Hays fly wheel is hitting and the motor goes both ways than stops at about the same place. I don't really want to pull it all apart. I put the floor in already and the engine bay has minimal clearence. Any one else run into this? Any ideas? <img src="graemlins/sweat.gif" border="0" alt="[sweat]" />

I pulled the starter out and I am unable to tell where it is hitting. It looks as though it may be hitting the added weight for the externally balenced flywheel. This is the only thing that looks odd. I have never run a 454 before (externally balanced)

Take a look at the end of the torque convertor bolts and see if they're hitting. Hayes makes a good product so I doubt that the flywheel is the problem. Any filings in the bottom on the dust cover? I'm trying to use some logic to solve a problem that is probably something simple.

Did you put on a GM water pump? I had my balancer where its detented hitting a tab on the water pump and I had to cut it off. Its for their assembly process. It would rotate a little ways then lockup, until I looked up front.FYI

The water pump is on but no pullies or fan. I am disconnecting the torque converter and turning the fly wheel to check the bolts. All of this sounds easy and I suspect it is something very simple. Just frustrating! <img src="graemlins/sweat.gif" border="0" alt="[sweat]" />

Make sure that you have .015 clearance for/aft on the converter to the trans pump. This can cause a problem if its bottomed out. Or if the converter came out of location to the pump.
