<div>Perhaps they assume the plate is worn and replacing it will help to prevent
cam “walk” (which can possibly cause erratic ignition timing issues). Or maybe
there is a thickness difference from early SBF engines and later engines?
Perhaps the oiling slots were modified for better oiling??? Anyway, these are
the only things I can think of that MIGHT be the reason. Hopefully someone has a
more definitive answer.</div>

<div dir="ltr">Hi,
<div> </div>
<div>I bought an Edelbrock 7820 timing chain set to go on my 260 and the
instructions say to remove the original cam thrust plate and spacer and replace
it with Ford thrust plate # C9OZ-6269-A. These instructions do not
explain WHY the plate needs to be replaced. I called Edelbrock and the guy
I spoke to was useless. I pointed out that the Ford part number they
listed appears to be obsolete and his response was to send me a link to Ebay
where an old one is for sale. I've found some other vendors that have
replacements for this number. Does anybody know why a different thrust
plate would be required for the Edelbrock timing chain set?</div>
<div> </div>
<div>Thanks,</div>
<div>Joe Brown</div></div>
