Okay. So even though the big end of a small block Chevy would fit around a 292 crank, the length is way off. The longest SBC rod I've seen for sale is 6.25". I believe Mopar has a 440 big block rod that measures 6.76" though, and is available forged. Don't know if the big end is the right size though.
And 2.09" is a little too large to find an off-the-shelf 283 forged piston to fit.
Someone's gotta make performance parts for 292's. They were race engines for years back in the day. Maybe I'm just not looking hard enough.
