Brainstormin' 440 vs 5.9 ...

I think the 440 will run out of rpm's with 4.30's. But, one never knows. The 5.9 crossed the line at about 5500 or so

Without a cam and springs,, I think you're right..
My 440 will wind to 6500, but it's just as fast, and quicker shifted at 5900. (Purple shaft solid).
