Dave_J said It has always been amazing to me how so many people LOVE the Chevy 327 but hate the 318. Just a little more than 9 CI differences. I think the 1968 Camaro with the 327 2bbl made 210 HP, but the same year 68 Barracuda with a 318 2bbl made 230 HP. Chevy 327 is a 4" bore and 3.25" stroke for 326.73 CI Mopar 318 is a 3.91" bore and 3.31" stroke for 317.5 Click to expand...
