Stock FE not setup for hydraulic cam/lifters ?

[427HISS]

Please explain why and how to know if a block has been changed ?

My first 1963 406 block I ran was a "solid lifter" block, as it was not drilled for oil galleys for the lifters.  It had the main galley in the middle, but the two outer galleys that connected the lifter bores were not drilled, along with the connection from the center galley.  That was early 60's stuff.  Don't know when they drilled all of them?

My 64 PI is not drilled C4AE-A

You will have to take the small plugs out of the back of the galley that runs down the center of the lifters and see if the ones below them are plugged off.Any block that says hp is solid lifter but the 68 427 is not i dont no about the ones for industrial.

Actually, when Ford first offered the FE (as a 332 & 352 in '58) they all came with solid lifters. They weren't 'mushroom' style as was seen in the Y-blocks, but solids, nonetheless. Shortly after the introduction, a running switch was made. After that, solid lifters were a 'performance' thing.

My '64 PI engine came from the factory with solid lifters, but the fore-'n'-aft lifter galleries were rifle-drilled. But the 'tower' in the back of the valley was untouched. I had it drilled and then two sets of screw-in plugs inserted so that the solid roller lifters I put in would get more than splash-oiling. I grooved the bottom part of the lifter bores to provide pressure oil to the rollers. Comp makes a tool to do the work.

Do any of you have photos showing these ?

What is the tool named ?

Look in the Comp Cams catalog under "Lifter Bore Grooving Kit"

Quite easy to use.
