Were they file fit, or exact fit? Typically around .008"-.010" compression ring endgap is acceptable, but up to .015" will work, but it might use a little oil @ .015". > > What kind of bearing clearence do you have? I think on a 350 chevy, you need around .0025 max on the rods, and like .004 max on the mains. I am not sure if the 400’s are the same, as they have different journal sizes. > > When you turn it over by hand is it really hard to turn over? Is there any noises that would sound like contact between the valves & pistons? > > Do you have a 168 or 153 tooth flywheel? 400 small blocks typically had 168 for better mechanical advantage for the starter. What kind of compression does it have? If you got higher compression & 153 tooth flywheel, you may have issues. Ring gaps were .011" -.013" They were exact fit. clearances were .0025- .003 on the rods and .003 on the mains. stock compression, and a 168 flywheel, I think i got it at advance and the part number was 04315. I pulled the torque converter bolts from the flywheel, and pulled the plugs again, now it will turn over, but not as fast as I would think a normal engine does, it seems a little slow to me. No noise like valves wacking piston tops though. --- _[View the full topic](https://forums.speedlife.net/t/wtf/189211)._
