BB TTI 2" header hot start problem
Looking to see if anyone else has had a hot start problem with a Big Block A-body using TTI 2" headers, 440-200.
My 493 4 spd runs great w/ 33 degrees of timing but when the car has been run for a while and it's hot, I cannot get it started, starter grunts but wont turn over the engine even with a jump, almost have to get a push start to pop the clutch.
Engine runs about 190 in Florida weather, using a freshly rebuilt RobbMC Performance starter # 3005 with the battery in the trunk.
Ran an auxiliary ground cable from the cross member to the 4 spd. Running an MSD 8987 start & step timimg control to retard the timing but haven't verified that's working correctly or not.
The headers are coated but come very close to the starter and I have wrapped the closest tube to try minimize the heat radiating to the starter.
Can't enjoy my 69 GTS bc it's not dependable (and very hot) - stuck right now - open to suggestions.
