You can see two 292's at my house! The 230-292 share the same bore size of 3.875. The 292 has a stroke of 4.125 were as the 230 has a stroke of 3.250. That is quite a difference in size. The gmc 302 has a 4 inch bore and stoke making it the tallest deck 6 cylinder in the gm line. Why? It had 7 inch connecting rods! Thats long! Now think about the bore and stroke of a 900 cubic inch cummins diesel. Whew! Scary! If you were to bore a 230 .125 over it would go to a 245. Ad a .125 over stroke it( i think) would be around a 255. So it still has a long ways to go before it will catch up to the 292. The 292 has a pushrod cover size of 6 inches were as the 194-250 have four inch. Chevy would have been smarter if they did a bigger bore on the 292 instead of the long stroke. Put a gmc 302 up against the chevy 292 and i would bet money that 302 is gonna win every time. Also one more thing, the 292 has a connecting rod length of 6.700 so not to much smaller than the 302 gm.
