on the 351 that actually is threaded into the timing cover. If so though you could have it off in about an hour.i found the cause of my timing problems - my distributor hold down threads are stripped. It is a 390 . Is there any downside to inserting a heli-coil? Can i get away without having to remove the intake?
Both the distributor hole and the hold down screw hole are in the intake manifold, about 1/8" apart, if that. There is nothing on the other side; that is, when you look in there you're looking at lifters and pushrods. The intake is an aluminum Offenhauser unit that was on the car when I bought it, and it's probably about 3/8" thick there.Maybe I'm missing something here but, is it the stud that's striped or worn or the engine block?
