I-6 vs. V-8

[Neibe]

I was wondering if it is possible that our motors being I-6 configuration that they continue to make power almost endlessly. Vs. a V-8 being a more high reving but not having as much grunt. Kind of like batteries you can have 2 batteries both having 700 cca but one of them having 150 min. of reserve capacity. The one with more reserve will crank 700 cca for a lot longer. I've heard from several people who have owned Ford and Chevy and Dodge that the Dodge will out pull them all in the hills. Now the Chevy and Dodge have 325/610 but from what I've heard like from contractors that have all 3 that the Dodge out pulls in the hills. Is it the longer stroke,I-6 config. ,the massive crank and flywheel just keep chugging along?

i-6, more stroke, thicker rods, one rod per journal, and seven main bearring, more torque but less power in higher rpm because of the increased drag from the longer stroke. V-8 has less stroke, thinner rods because two per journal, five main bearrings, less torque because shorter stroke and lighter rotating mass. The V-8 will make more power with the fuelling, but they will be kept down until they find more ways to strengthen their engine. V-8's also have a turbo advantage over are i-6's because they can use more of their boost because it comes in at a more efficient time for them. We need air before 3k and they can use it after 3k.

Wow! What a simple, succinct answer! I really like the power characteristics of the I-6 better than the gasoline big block "imitators" and I basically understood (before reading your post) why they were different. But I never knew the exact physics of the "why" that makes these differences in power delivery. Very interesting.

The I-6 also are naturally smoother running as well.
