    OK, I accidentally burned my haynes manual /forums/images/graemlins/angryfire.gif (long story) and haven't gotten another one yet. Can anyone look up the clearences on the connecting rods for a 305? I think the acceptable range is between .006 and .014 but I'm not sure. The one I'm about to rebuild is between .008 and .012 just wanted to check to see if that was ok. I'm ordering my dress up kit so it'll look purrrrrrrty /forums/images/graemlins/thumb.gifand wanted to make sure I didn't need to order rods too.

    Thanks, So far I've got that done and checked the decks and bearing clearances and bearing wear. All the plastigauge shows it right in the middle of tollerances, and no warping. I believe I may get away with just a bore and hone on this block after I get it boiled.

    My daughter helped me get the heads off yesterday and we started getting the measurements to see what we needed. Looks great for what I need. Rings and valves were leaking bad just like you predicted, but the bottom end is good. Thanks, Exactly what I wanted. Bearings had perfect wear on them. I haven't gotten the crank out yet to see if it has any out of round to it, but with the bearing clearences all being right I doubt it. Like I said, mine's got a light knock in it so I'd like to get this one in this summer. Stopped off in Atlanta and picked up my new rear bumper to modify since I keep tearing mine up with the trailer.

    Glad it's working out for ya'.... That poor motor had been abused by me for quite a while before I finally put it out of it's misery. I guess I didn't abuse it as much as I thought though. /forums/images/graemlins/grin.gif
