Well, boys and girls- - - -I am now the proud owner of a modified 292 connecting rod! By adding a bolt-on spacer to both sides of the rod cap, the rod will center up on the 235/261 crankshaft journal without doing that Rube Goldberg-looking stepped down crankshaft regrinding job. The spacers are machined from a big flat washer which is cut into two pieces, and they are attached to each side of the rod cap with three flathead screws, and machined and ground to the proper width. Since the only function of the spacer is to center the rod cap in the crankshaft journal, nothing needs to be done to the rod itself. The spacers are approximately .100" thick, which makes the rod cap the same width as a 235 rod. Just regrind the rod journal to 292 size, and offset it to make the stroke 4 1/8". With a 60 overbore, the 235 becomes a 255, and the compression goes up about one ratio. "Hello, torque!" Now- - - -just gotta do the same thing five more times! I haven't decided yet if I'll need to do a little low-temperature silver soldering to make sure the spacers stay put. If I was planning on building a high-revving race engine, definitely- - - -but since the whole purpose of stroking is to increase low-RPM grunt, doing a bunch of high-speed stuff is sort of pointless.
