Finally got the new motor in my Gto fired up today. It had a dry new carb and lines from the tank. I did fill the Qjet through the vent tube but I don't think I had enough in there at first as it wouldn't quite start til I added more gas to the carb. We did have to crank on it many times (less than 5 seconds each time) after that, even though I could tell the carb was squirting gas, probably due to not having the distributor close (stock w/pertronix) before it would fire. We did get it started a couple of times but timing was off so wouldn't bring revs up to 2000, so immediately shut it off. I did have EOS in with the 30 weight oil, so hopefully didn't harm any lobes. After I got the timing closer, it started and got up to 2000, it ran pretty great for about 10 minutes. Of course the paint was burning off the exhaust side of the heads and exhaust manifolds but no weird noises or anything, but then it started getting really warm (according to my rally gauges). Just as I was about to shut it off, a loud metal to metal schreech noise happened. It sounded down low in the engine, almost like two rotating parts rubbing on each other. Kind of a "zhing" sound. Well, I thought it was seizing up so I shut it off. I have a T400 tranny and since I didn't want to have deal with watching the motor and trying to fill the tranny at the same time, I left the torque converter un bolted from the flex-plate. Could the torque converter have walked forward just enough to rub against the flex-plate? After I shut it done, I got underneath and was still able to turn the converter and it didn't sound like it was rubbing, but maybe???
And, after I shut it off, I thought the radiator would be boiling over...nope. Not at all. I used the trick from another post about drilling a couple of relief holes in the thermostat to prevent air pocket. The upper radiator hose was warm, not hot, so I believe the tstat had opened. If I still had the timing too advanced, would it have gotten that hot? I had the vacuum advance connected. Here are a couple of pictures of where the paint burnt off (por15 engine paint guaranteed not to burn off, riiiight). Does it appear it got too hot? Also, when I took the cap off of the radiator, there was some brown sludge floating on top. Picture included. There is no water in the oil at the dip-stick. Rust or something from the block not removed from hot-tanking? Heater core? Should I drain the radiator and put fresh in before trying to run it again? I know I need to run it again for at least another 10 minute or more to finish the break-in process. I have since got a large box fan I'm going to place in front of the radiator before I try this again. I know Pontiacs run warm, but does a new motor breaking in get warmer? Sorry for the rambling, I want get this right before trying again and really hurting something. Jeff
