I think the ratio was increased only due to the 848 head being used was it not? I have a chance to get three 261 full engines from a guy. I already have a 56-57 261 block cleaned up and checked for cracks for a rebuild but if the 60's blocks are better i could always take this opportunity to change over before the machine work is done. Having a fully filtered oil system is not a priority to me. (or should it be ?)
