Re: 390 lifter replacement.
Well it can be done with some factory intakes depending on what location the lifter is in. It's tricky and you need to fish it out with one of those long extendable magnets. If the valley pan is in place it's a lot harder to get at too. There is just enough room if this is a lifter that's in the open space on the intake. If it's under one of the pushrod holes that goes through the intake it's very hard to get at. How bad is the tick? How does it run otherwise?
