2 part question On some small blocks there is a bolt going thru the upper left hand corner of the cam thrust plate. This bolt has a hole thru it allowing oil to go from the lifter valley to drip on the timing chain. What size hole runs thru the bolt?
Next question I am building a 360 and putting a timing chain tennsioner on it. When I took the bolts out of the cam thrust plate none of them had holes as mentioned above and the timing chain tennsioner only has 3 holes to bolt it on 2 above the cam and one below and to the left.
With this type of set up how does the timing chain get oiled?
