Re: 347 stroker in a bored .060 289?
I wouldn't go over .040. Also, correct me if I'm wrong, but aren't the 302 cylinders a tad deeper than the 289 to accommodate the longer stroke of the 302 crank, let alone another 4/10 of an inch with the 347 crank? Just curious, but I thought that to be the difference between the 289 and 302 all else being the same (deck height, bore, etc.). If that's the case wouldn't another 13/100 on top of the 4/10" be kind of a deal breaker being the total stroke difference is over half an inch (.53 to be exact)? I could be wrong about all of this but my thoughts are that if the 302 has deeper bores to accommodate just a small difference in stroke, then wouldn't the combination of almost 1/2" of stroke along with a shorter piston, put the piston below the bottom of the cylinder, or at least dangerously close?
