Update... my gracious father has let me know this evening that he got the correct fan clutch (thermal), stuck it on there and it's working well. He also let me know that he simply used the injectors vs. swapping the TBI and injectors both. That also seems to be working good. During a test drive the temp never got over 1/4 on the gauge, after the drive and/or sitting still at stop signs etc. Happy day. So now that's it's cooling ok, he says he may wait on the radiator until a bit later (less $ for me to owe him). Over the next couple of months, I should certainly be able to swap out the radiator but in the meantime I will certainly ask him to have it cleaned properly or possibly fixed (recored) if possible. As for the airlock, nothing mentioned as of yet. He is concerned for the possiblity of engine damage relating to it getting as hot as it did. Are the heads on this and/or the 2.8 aluminum? The 3.4 is from a firebird...supposedly. Unfortunately I didn't get to see the car it came from, just the engine hanging from a crane. Been a long day here at work, first time we've filled all the beds here at the hospital. I work on a gero/psych ward and was hoping they would save me a bed here if I blew this 3.4 to hell...going home. Good evening.
