I'd add that you should go to the
www.FordFE.com and search the archives on oiling mods for the FE. There are widely differing opinions that you should think through yourself.
In my opinion it's a good idea to chamfer the main bearing
oil holes to align with the bearings, run a high volume pump and your increased capacity canton pan. It's unfortunate that you already have cam bearings installed, any oiling mods you do will make chips that will be hard to clean out with the cam bearings in there, so maybe you should skip the oiling mods.
Do contact Doug Garifo at Precision
Oil Pumps. You'll want to get his rocker shaft end stands at least and I'd recommend his
oil pumps, drives, and rocker shaft studs.
The deal with the rear main cap needing to be machined is only if you've installed ARP studs in the mains. The nuts stick up too far so you need to machine the cap to allow the canton pan (and windage tray if you have it) to sit on the block. Also ARP recommends you have your block align honed with any change of main fastener type.
And do find a good machine shop that knows FEs, the cam plug cups out not in, etc.
www.gessford.com or
www.keithcraft.com are good ones, but if you ask around you may find a great place in your area.
I'm getting ready to start my 3rd FE build, they are fun and interesting engines to work on. They do have some unique features that might throw off the average chevy oriented machine shop.
