Pushrod
#1
What is the length of a pushrod for DOAE 351C-4V?
Have a book about performance Ford engines and a
lot of info but nothing on pushrods.

Part No. D0AZ 6565-A for Cleveland engines is 8 7/16" (8.4375") long. They were also available 0.062" shorter (-B) or longer (-C).

That may explain something. Bought this engine from Don as a long block.
My mechanic claims he and a friend measured valve lift at 0.58 . Ford made
a cam with that spec for racing use. Don heard a recording of the engine and
says it does not sound like that cam. But a longer pushrod would produce that
lift with a less radical cam? We don't know who rebuilt this engine but they did
a really good job! My mechanic worked on these in high school late 60's early
70's and made good money.

Mike, There is a lot more going on with pushrod lengths. This is a very good article on the subject. https://www.enginebuildermag.com/2017/03...y-impacts/

+1 excellent article
Measuring push rod lenght is a must if anything has changed in the engine. It is a simple process that needs time. I did it recently by measuring the in/ex of #1 and #8. Then double checked with #2 and #7. In my case.

Yes, good article.  My mechanic still thinks when they went to deliver
this block to Don they picked up the wrong pallet. The shipping tag
read deliver to NASCAR Big Grin
