Just had my 455 rebuilt. The builder put on a higher capacity Toronado oil pan. My thinking is that the original dip stick should give me the proper oil level reading due to fact that it is in relation to the oil level and crank shaft which has not changed. Any thoughts on this would be appreciated.

 

Your reasoning is correct. That pan with the correct filter takes 6 qts. After you run the engine and let it cool just verify the dip stick reads correct.

 

Thanks for your quick response.

 

I always verify a new setup after an oil change. I use a hand file on the dip stick to scribe a full line if it's off.

 

Your bigger problem is that the Toro pan is not a great choice for a performance application. The "notch" forward of the sump to clear the front axle shaft traps oil in the front away from the sump, which negates the additional capacity. As for higher capacity pans, one reason to run a larger pan is not to run more oil but to lower the oil level relative to the crank counterweights to minimize windage losses.

 

^^^^^, not a good choice.
