My New World Block 472 Hemi has New 2 1/8 " TTI Nickel Plated Headers with a Denso Mini Starter. This starter was listed on the TTI installation instructions sheets as one of the 5 starters that will work with the TTI Headers and Schumacher Engine mount combination. The existing starter was on the previous Wedge Engine that was in my 1965 Belvedere I and it performed perfectly. Just to be safe, I had the starter checked and nothing was found to be wrong, but I still had it totally rebuilt anyway. The starter work was completed by a highly competant local starter company here in town. I have a thermal insulator wrap around the rear portion of the starter where the solenoid is located. I fabricated a starter shield out of 1/8" aluminum, but when installed the starter shield touches both the header and the starter as there is next to no room between the drivers side header and the starter. The header and the starter are RIDICULOUSLY close to each other. The engine's total timing is set at exactly 32 degrees per the directive from my engine builder. The starter engages perfectly with no hesitation when the engine is cold, but after driving the car for 30 minutes or so in hot, humid weather and shutting it off, it will not immediately engage upon trying to re-start the engine. Upon turning the key, it completely hesitates for a nano-second and then it reluctantly engages slowly turning over like the timing is too far advanced. I spoke to ( 2 ) TTI engineers that both said they are stumped, they offered very little valid suggestions and stated that I am the only person ever to call to complain about this problem. BULL ! ! ! At the TTI engineer's suggestion, I removed the aluminum starter shield and it still has the hesitation when the engine is hot. I am out of suggestions. Could I possibly have an electrical problem totally isolated from the starter, such as a bad ignition switch, bad starter relay or a bad connection at the firewall terminal block ? Any thoughts or suggestions are appreciated.

Thanks Moparts...
