Hello, I was tearing down a 351w ho from a 1986 f150 and I noticed a hole in the block. It's under the intake manifold, and when you look through it it goes to the timing chain. I took a photo from the front side of the engine and it looks like it might have a crack running down from it. Is this block worth keeping or should I get another one?? This one is a little wprry some too.....
In this day and age, hang onto the block, even if you replace it... Hole and crack is repairable. Could be a worth while spare to keep around... Just sayin'
It's right in behind where the cam timing gear is. To the right of it is where the distributor goes in. I also checked the ring gap and its .003 over what the max tolerances are.
