Summit Cam Recommendation

I know you can do the math , but that looks like 74 degree ramps, compared to 44/46 on a Comp/Hughes/most everybody else,etc
That's about 15* more at each end!
On the Wallace , that is worth about 21psi and very substantial difference in low-rpm torque/power, not to mention the potential loss in fuel economy due to the about 18* less power-extraction.
I know the 4.10s are gonna make up most of that low-rpm torque loss, but do you realize that your compression plus power duration (209*) is about the same as the 292/292/108 cam (212*)? And we know how poor the fuel economy is with that cam.
I also know that once your revs are up around 2000/2200, that part of the cam don't account for much anymore, but that short extraction is still gonna be a bit of a problem. I'm thinking 6000 miles with a faster cam will pay for the difference in fuel savings alone, if the shorter ramped cam gets just 10% better fuel economy, due to the nearly 20% better cylinder pressure..
Unless maybe the advertised duration is at some other tappet lift than .006, where most every body else measures from. Summit doesn't say. But even if the measured from .002, I can't see more than 2 to 4* per end difference from .002 to .006, so IMO in an 8/1 Scr DD, that cam is trouble.

I wonder if the factory 360-2bbl cam wouldn't be a better selection. You must have a good used one kicking around with a little life left in it, Hey? Hyup it must be close to 204/214(.050) without the long ramp penalty. I think it was advertised at 252/260/112.. I put one of those into a low-C teener with a 2800TC and 3.23s, and she boogied pretty good, even without headers. I could probably scare one up around here but with shipping and border crossing and new lifters down there,even if I gave it to you,it would probably be more than new ,lol.
