Just a question from a complete novice. Assuming we have a 455 with iron heads and close to 9.5:1 compression. Which of the following intake lobes would be considered larger?
Xe274-274 advertised, 230 at .050, 0.488 lift
Crane- 288 advertised, 226 at .050, 0.458 lift
I would have assumed the xe274. But does the crane make up for the lose of lift and .050 duration with the extra seat timing?
