Thanks for the good news about the Olds and trips getting that milage.

I'm building pretty much the same setup for my '39. I have a mild 30 over 394 with the same Offy intake and 3 rochesters you are using.

I guess it is time to order that 15 gallon moon tank to replace the 10 gallon one I have now???

But, don't you love them Olds??? I grew up shoving Olds engines into any car I could get my hands on, and they were THE ENGINE back then. They are still my engine of choice for old timey rods.
