i need help on this one...i'm assembling an early model timing cover on a crate 5.0. problem is, i got a set of stainless bolts for the pump and cover, but i'm not too sure which size bolt goes in to which hole. the manual isn't clear on it either. any suggestions? btw, the bolts are a set my buddy sent me, stainless steel, and are guess-timates of what may be in a set from arp or the like. so bolt sizes and placement would greatly appreciated. thanks, jeff

Jeff,
Almost all bolts are 5/16-18 threads except the bolt that holds the lower alternator bracket which is 3/8-16. Now for lengths that is a trial and error. Over the years I have found that most of the stainless bolt sets are generic in nature, they don't always have the correct lengths. Ford made alot of changes in the casting heights on the waterpumps and front covers and brackets. I think that the 5.0 even use a couple of dowels to locate the front cover. Just make sure that you have enough thread engagement. An old toolmaker theory, is whatever the diameter of the bolt is make sure you have that length of threads engaged. Don't forget to use anti-sieze on the threads and sealer on the four that go into the water jackets.  Mike

that tool maker theory is good as long as ur not screwing into allumminim then u need as much as possible without causing a prob since its so soft i have seen heat pull shallow bolts out if it just thought i would add thet ------------------

I have the original 65 timing cover with alum water pump.on my 89 5.0 for that period correct look. Last time for that stuff! Anyway, I bought an AMK bolt set for water pump, and it didn't work too well. Had to go to my bolt collection. I measured depths with a piece of welding rod. The water pump bolts are black like the motor so wasn't too particular about original markings, which can't be seen anyway. Nary a leak.
