Re: Need 250 I6 info:
292 has 3.875 bore and 4.120 stoke, 250 has 3.875 bore and 3.530 stroke, and the 230 has a 3.875 bore and a 3.250 stoke. Basically the 250 is a stroked 230, and the 292 would be a majorly stroked out 230 if they were the same block. The Gmc 302 has a 4 in bore and 4 in stroke, and 7 inch connecting rods! Making it the tallest deck 6 cylinder on the gm line!
