"Strange thing is this block has no provision to select full flow or bypass for the oil. Im just not used to seeing this style of block. I also wish it had the 3 hole mount so i could have used it for a remote filter mount but i will make due."
Only the 1958-1963 USA 261 truck blocks were set-up from the factory to allow:
- no oil filter
- by-pass oil filter
- full-flow oil filter
Once a full-flow oil filter was properly installed, you could not "go back" (I think).
