Pat,
I agree. That is the method that we always used with race engines.
But we would on first cold start of the day, remove the plugs and crank until we saw good pressure for about 10 seconds.
This was more for upper end lubrication then any other reason. (Also, some of the engines idled at 2500 rpm and there was worry that the high rpm at startup would do a bit of damage without fully lubing the cam followers.)
I really wonder if a pre-oiler such as a Accusump/pressure pump etc. would do any good for upper end lube on cold start?
Or is pre oiling really needed at all for the relatively mild engines one puts in these cars?
