Ok I just got this motor which is a 305 but it's been rebuild. The pistons are still shinny lol, all new freeze plugs and the motors been decked I'm pretty sure, but I need help on trying to figure out what it is. I've looked everywhere and can't find a good answer and I can't get some sites to work with my iPhone, so the block is 14093627 and another is d129 and heads are 14102187. And back to the motor being decked, on the front of the block on the pad on the passenger side where the numbers are. There is not any numbers at all. I read that if the numbers are gone then it's a good sign that it was decked.
