RE: EDC-E revisited |

Yes, I'm still lurking around. Career change has made it more difficult to participate as much but I like to check in to see what's new.
I'm not sure I can help you a lot but what I have for information is all thanks to you from that post a few months back breaking down the casting codes/dates from a Ford service letter, M-167A.
Here's what I can tell you:
7BQ head....cast in Cleveland, 12/16/57, No Core plugs.
7BR heads....cast in Dearborn, 12/17/57, No Core plugs.
I agree with you that the use of the EDC-E machined cc heads went way beyond the first 90 days of production. I believe the non machined cc head is more rare on a '58 Interceptor engine. I can't remember the casting of a non machined cc head.
What I think is that the solid lifter cam was definitely a first 90 day thing. All had the shell lifters too which worked out fine for blocking the lifter oil passages.
Which leads to questions as to why FoMoCo even introduced the Interceptor 332/352 with solid lifters when the blocks were drilled for hydraulics. I'm sure there's lots of speculation of that.
Thanks for asking about the '60 Sunliner too. It's coming along nicely. Front seat's all done and in along with seat belts so that now I can road test it a lot more comfortably. I'm actually about to get license tabs for it.....this'll be the first time the big drop-top will have been licensed sinced '68.
