What is the correct fast idle RPM for a C - 1 245 HP? Thanks, Jimmy

Re: C - 1 245 HP Fast Idle RPM

From the 53-62 Corvette Operations Manual & PV Test Guide:

"On all but six-cylinder manual choke engines, full, fast idle speed is specified to be set at 1700 to 1800 RPM on a FULLY WARM engine."

That means when you cold start the engine, initial idle will be lower (could be as much as 50% depending on ambient temp) and the speed should increase as the engine warms converging to the 1700-1800 RPM range if the accelerator isn't touched to let the choke's high idle collapse...
