Old horse new beating cam question
I didn't see anywhere what the point of the new cam is.
Is it for added performance, or sound of the exhaust?
If for added performance then the cam is going to be different enough to need new springs and lifters, and then as a daily driver you will have to be careful about destroying the fuel economy. (and low end torque is critical for a daily)
If the point is just to make it sound a little meaner, get a cam made just for that.
Like a mild lift Thumper cam.
For my daily driver with a Magnum motor I got a cam from Oregon with 214/224 duration on a 110 lobe center.
It has a nice little noticeable lope that people comment on a lot, but right off idle it's smooth as can be and gets good fuel economy.
