FE oil mods nessary?
I was wondering how nessary the FE oil mods are? I tried to get an estimate from my machine shop on the oil mods for an FE and the dude acted like he never heared of it. He's proably a chevy guy. Anyway, I wanted to know would it be okay to just get a melling HV pump and not do the mods? How much is it going to cost to have the machine shop do it?
Thanks

It depends on how you are going to run the motor. A stock rebuild will not need any help. Lord knows it made it 30+ yrs now. If you plan on hot rodding it at all, I would suggest the oil galley mods and the pump. You definitely want plenty of oil to the mains to keep it alive.
If you could get the drill bit, you could drill the lower galley's yourself. Do the oil pump mount hole, polish it up to match. Most of it is not majic, you just need the tools.

ratsmoker, on your oil mods page number 2 says to chamfer the oil holes in the main saddles to match the main bearings. Before I couldnt picture what you meant but its now aprt and I see exactly what you mean. The oil hole in the main saddle doseant line up with the bearing, and that needs to be chamferd so that it does line up, am I correct?

If your going with a stock to mild rebuild, I don't know that I would even put on the HV pump, but if you do, you may consider an extra quart of oil and the restrictors in the heads.

If you want to restrict a motor, that's the way to do it, right at the oiling point instead of upstream somewhere. Question is do you want to restrict it?
For a stock motor, I don't think you need the oiling mods. These FE's have run for hundreds of thousands of miles and I don't see cranks getting thrashed left and right. JMO

Yeah, it is kinda funny though. In Steve's book he even gives a way to measure the restirction in the mains with drill bits. I quote:
" There is a way to make sure the restriction is correct. Measure the oil holes with, with the shank of drill bits. The following chart lists the drill bit that should pass through the bearing into the oil hole.
#1 7/64
#2 9/64
#3 9/32
#4 5/32
#5 9/32
If the opening is not large enough he recommends removing the bearing itself and opening the hold in the BEARING to get the proper restriction. No explanation of why Ford designed in this restriction though.
As for myself I did the suggested mods on the block figuring it would be more forgiving then the bearing. Actually did this mod using the old main bearings before I took the block to the machine shop. Since they do a clean and bake on the block, cleaning all galleys and such, I figured they would do a better cleaning job then I could. Besides which I had them line hone the mains which also ensured that any "burrs", or other discrepancies in the main bores that I might have missed, were no issue during the build.
Sorry for the length of the reply.
