Mike...I see John from Aviaid gave you some additional information on how to mark your dip stick for the 9 quart Aviaid Road Race Pan.
On the subject of
oil pans... I have and will continue to provide original equipment manufacturers products when ever I can. I feel it's important to provide every possible original detail that reflects the true spirit of the Cobra from the 60's. Aviaid provides an exceptional product in very low volume that can handle the extreme requirments for this application...and they do it in the original style and design. They have continued to offer dry sump and many other versions for the true Ford builder.... supporting an original manufacture is what I always like to do when possible. The other brands of pans are certainly well built and offer great performance as someone mentioned...they just aren't the companies that have served this industry since the 60's like Aviaid...Aviaid has the
oil temperature sending boss in the right place, the correct puke tank boss and other small details including the decal that I appreciate and the others don't ......even if they aren't needed....Aviaid holds to the original design and style...it adds value to the Cobra in the long run. I've been running one on my 427 since 1993 and the old dog just keeps on running....always great
oil pressure under the severest of Road Race conditions...so this I recommend from experience... I agree Aviaid is not the least expensive but I believe well worth the investment for a proven history...
My Best, George
