Hi Eldon,
When you get the thermostat type confirmed (180F vs 192F), and the mechanicals configured to your liking, just let me know what fan parameters you would like to try. I will change them as many times as you need, until both you and your customer are content.
Despite comments to the contrary, the fan settings suggested in post #26 will work just fine for a 180F thermostat, as long as the overall cooling system is adequate.
With a naturally aspirated engine using a sufficiently robust cooling system, and ambient atmospheric temperature in the 80F to 90F range, a 192F thermostat will generally stabilize ECT at, or just above, the thermostat rating. A 160F thermostat will generally stabilize ECT in the low 170F range (generally 172F to 174F). A 180F thermostat will generally stabilize ECT around, or just under, 190F.
Every custom vehicle is unique, only you will know what will or won't work correctly for this particular combination.
Cheers,
Taz
