The 49 runs hot on the gauge within a couple of miles and after 10 is overheating. Block and rad have been flushed cleaned, scoured etc. no indication that water pump is malfunctioning. Timing is where it's supposed to be. I'm at wits end. Does anyone make an aluminum rad for 49s? I've found them for 39s. Do I take out the thermo? Head gasket has been replaced, head decked. 3 speed od.
