Yep Gjac, we just did a sheet of paper test to confirm. It is pushing air out of the radiator. We're going to call the shop here in a minute to confirm the P/N on the water pump, but I'm betting this was the original issue. I'll update later when everything else has been sorted. I also still want to confirm the initial timing after this is all done, because lord only knows the last time that was checked.

Yes, it sure looks like it. As far as timing goes 454's run much better when you advance the timing some I run mine at 9 degrees BTDC. Some even go up to 12. You will get a performance improvement when you do. I would also check your radiator with your IR gun in a 4 in grid pattern from the top inlet to the bottom outlet and write the temp readings down. You should see an even temperature drop across the whole radiator. Pay particular attention to the center for cold spots which would indicate a blockage. From inlet to outlet you should see a temperature drop of at least 50 degrees if you have a functioning radiator. Also shoot the thermostat housing to see if the temp reading corresponds somewhat to you dash gage reading. Hope this helps.
