I am currently building up my new motor on an engine stand, I have the bottom end together and was starting on the front cover.
I have a new Cloyes Billet Steel Timing Set, I am replacing a early 90's Ford Motor Sport roller timing chain and gear set. The Ford gear set had the one piece eccentric originally that I plan on using on the Cloyes gear. The Cloyes gear is a little thicker so I had to go to with a 1.5" dowel pin up from the 1.375" pin used on the original Motor sport gear and chain.
I currently have about .050 clearance between my one piece fuel pump eccentric and the timing cover.
I have turned the motor over by hand several time and there is no contact.
If my Cam end play is about 0.007 and I assume the aluminum cover will grow a bit when it warms up as well as the timing gear let's say 0.01 total gear + housing expansion, then I should have about 0.050-.007-.01 = .033 stack up clearance.
Does that sound too tight to anyone besides me? In theory, nothing should be moving, but seems too tight.
Has anyone else ever had a tight situation and measured the actual clearance?
