GTX Matt- thanks for the heads up on the intake. I was hoping to keep my 4150 based carb and nitrous plate kit but if there is a ton of performance to be had by switching it I'd consider it! After reading Andy's articles on his 470, comparing the 240 to 270, the 270's seemed like a no brainer. Engine Masters did the same test, the 270's were better everywhere.
I think the 0.590 cam has 0.393 lobe lift, which should be 0.628 before lash with a 1.6 rocker. I might be doing the math wrong though?
My mistake, I thought you were running the 557, you got it right!
And I’m not sure in the 4150 vs 4500 carb being a gain, but enginemasters ran an XP 4150 which is dual pattern. I’m still figuring out how I will run a 4150 on the intake (which adaptor), but if you’re going to eventually go stroker I would think a 4500 will help you.
I’m not sure that the extra plenum volume on the Super Victor didn’t help EngineMasters tests, and I’m scared to run the Indy 440 2D.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street
