In Reply to: Ridge cutting on bores posted by John B. on August 08, 1999 at 14:01:25:
: In the process of cutting the ridge on the bores of the 302 I'm building for my Mav, I think I cut too much out of one side of one of the cylinders. This is the first time I've ever used this ridge cutter and I didn't clue in to the need to center the cutting tool by opening it up to the full size of the bore before tighening it down, backing off on the adjustment and then starting to cut; consequently in trying to take out the ridge on the one side of the bore and not realizing that the cutter was slightly off-center, I cut slightly past the surface of the rest of the cylinder on the opposite side of the bore before realizing what was happening. Question is, is this going to be a problem or is the block still usable without re-boring (Please,oh please say it's going to be allright!). Thanks so much for your input, whatever the verdict. John B.
John, if it's bad enough that you had to use a ridge reemer it needs to be bored out. Sorry. It doesn't take much wear in those bores to start piston slap then you have no choice. If the engine is torn apart, which I hope it is, bore it the bare minimum, .020". If it's worth rebuilding it's worth doing it right. Boring will give you fresh cylinders with no worries. Watch out for Murphy's Law when working on engines. Or, "do it right or do it again".
