Cab,
I just warmed engine up with no load about 1,800 rpm, 7 tubes were about 850 degrees F. but #5 was 999? It's raining outside and I'm home alone so can't really check with a load on it until I drill and install thermocouples...Car has Hooker SC headers so 6,7 & 8 aren't easily accessable for sensors?
what would you suggest?
