When I first started racing at the drag strips in SO CA most of the Chevy guys would have a switch to shut the ignition off so they could spin the motors over on the starters to build oil pressure before every run and before loading or unloading the cars onto the trailers or trucks realcrazy down
Prime it before spinning it twocents

iagree Using the starter defeats the whole purpose of trying to build oil pressure on a motor that's been sitting for a long time. If it isn't a new build or hasn't been sitting a long time, I see no reason to prime it.


Actually we used an Accusump (as opposed to spinning the engine) to prime the engine before starting after sitting awhile or even overnight. Engine had pressure when it started. Made a difference in the stuff in the filter. But that's another conversation.

If the results don't match the theory, change the theory.
