I am ordering parts for a cam change on a 1993 EFI 351 and I noticed that there are two different versions, depending on if I have a 1-piece or 2-piece fuel pump eccentric. I have not removed my timing cover yet (I need to go borrow a puller for the balancer), so I have not looked at what I have. Could this year engine have either one, or would someone know which one this will have?

Thanks!

If it`s EFI it wont need a fuel pump eccentric,just a thick washer behind the cam bolt.

 

I just re-read my post and realized that I missed a few details. The part I am looking to order is the timing chain set. There were two almost identical ones, except that one specified that it works with the 1-piece eccentric and the other specified the 2-piece. After a little more searching, I found one that says "Fits engines originally equipped with two-piece fuel pump eccentric or fuel injection." I guess that answers it.

Thanks!
Dave
