Yup I understand the science behind the Rhoads perfectly. I run small cams for their streetability. I dont need hp at 6000. I need tq at 2200 to 4000ish. If I cammed my motor for 6000 I would need somewheres around a 250* plus cam, which the Rhoads would bleed down, as you say 15* to 235*, which is a roughly 2 or 3 cam sizes. I just start with the 235*, and call it done. The small 235* cam is plenty for the street, being able to roast the 295s from just off idle to 60 mph. Even the 223* I had was nearly as potent.So,Now if the Rhoads could give me a 223* at idle and a 250* at the other end, well, Im still not interested.
For a guy who spends some significant time at the track, wants to post some dynomite times, and then cruise around on the weekend, I totally get it.
But Im not interested much in that. My car is set up for bombing around,and posturing, and, the occasional blast to the end of the runway. A 235* cam is real good at that.It already has more low end and midrange than the chassis can handle, and I dont need the top end.
And lest you say that my chassis needs upgrading; She goes 93 in the eighth, with a 1.9 60 ft. So yes and no. Its all I want. And at my age I should probably be wanting less soon.
Again Im not trying to argue. I just think theyre not on my must have list
And thanks for explaining it to the OP, and the links.
