As far as Pontiac motors running hot I can say none of mine have overheating problems. My Firebird sat in traffic at Woodard for 2 hrs. moving not more than a few inches at a time and ran fine. I made sure it had all the parts that it should have when I restored it. As far as those that get hot and wont start I would sugest a good starter silenoid and a heat sheild. The exhaust pipe runs too close to the starter. That solved my starting problem.
