Over-filling Oil, for track use Options

[yarin]

I checked the level in my '72 track car and noticed the level is about an inch over full. The car has a tuna can on it already. Is overfilling an acceptable solution to oiling problems on these motors? If so how high over max is too high?

Also... i'm pretty sure the oil smells like gas. This is my first carbed car... can this happen when the engine floods? Or does it mean the rings are bad?

Thanks!

Let your oil pressure determine the best wieght oil for your climate and driving conditions. There is no blanket answer. Variables include how tight your engine is, worn bearings and pumps will require a thicker oil to maintain oil pressure.

You want as a general rule, no less than 10 psi for every 1000 rpm at full operating temperature. (the 10 psi minimum at near idle, can be a bit less, so long as the pressure picks up to 10 psi per 1000 rpm at 2000 rpm or so) Idle pressure can sometimes go to 5 psi, but you still are ok at 3000 rpm at 30 psi (this is a minimum value)


Also be sure your oil temp is not excessive, if you are overheating, thicker oil will not cure the main problem, even though oil pressure might be "restored' with thicker oil, you still do not to be running too hot.
