Can someone help me understand what the RPM's should be on a cold start for a 1972 LT-1 when the coolant temp is around 50 degrees? What happens with mine with the fast idle on the high step of the cam at start up, the RPM's go to about 1800 for around 30 to 45 sec. then a drop of 300 RPM's. Then it may take 3 minutes to climb to the 2350 RPM's without tapping the accelerator. Is this the norm? Thanks for any explaination.
