RE: Cam retainer & castings
By Mel Clark - 08/22/2001 12:28:09 AM; IP 152.163.207.201
I'm not certain which year Ford changed the design of the FEs cam and retaining system but I do know that the early blocks needed some machine work and different parts were required. There was also the problem of trying to get the latest design camshafts because Ford did very little in the way of supporting the earlier designs. If Ford wouldn't make "stuff" for their own cars the aftermarket sure wouldn't because they were assumed to be both obsolete as well as dead. The current phenomena of Edelbrock and others casting FE heads and blocks for engines that have not been produced in about 30 years is a matter of strictly business. They are driven by profit and I think the demand started in the Shelby/Cobra collector ranks searching for the ever elusive aluminum MR-HR-TP cylinder heads and has spread from there. The demand grew through the other Ford based clubs and now nearly all of the '60s designed engines can benefit from these products.
Ford castings and foundry technique undergo constant changes and usually improvement of product is achieved. In the early '60s Ford pioneered thin wall casting of blocks and heads by improving the media used in making the cores as well as new methods for eliminating core shift. This resulted in lighter engines and more castings per ton of ore. Because the Iron used in the earlier casting was of a more basic grade, the castings were soft, or not strong enough to withstand the stress as well as being quite porous. This caused a lot of research to be done so they could continue the thin wall process and have an engine that wouldnot leak through the skirts of the block or cylinder walls or into the tappet valley. They soon came up with a Chrome/Nickel/Iron alloy for block and head castings. This alloy was improved upon over the years and if you look at a '67 427 side oiler or SOHC block (both have screw in core plugs) you should be able to see that those blocks have a much smoother casting, that appears to be a tighter grain. And they don't have a predisposition to rust so quickly on the outside. For those that want an education in this regard, I suggest getting and reading some of the SAE papers that were submitted by FOrd in the '60s.
