I bought a long block 396 and the oil pan that came on it would not clear the craddle, I purchased one on this sight, which looked to be the correct one, 2/3 shallow sump, and 1/3 deep sump, well i installed it everything bolted up fine and now the engine will not turn. I believe the engine was out of a truck, this is the reason the first oil pan woild not work. The pan I installed has alot of clearance under the craddle, maybe too much??? Please help, I do not want to have to pull this engine again. Thanks
