Planning for 408 - Possible Solid Flat Tappet cams

the wider you go the more compression you need
and vice versa
pick the rev range you want
then your powerband
then work from there
most everyone here has autos
4 speeds are different
especially if street driven
work from .006 not .050
what the cam picker is going to do is pick your valve events
but you have to know sorta what works because, as seen in another recent thread, the cam pickers can be way off


Not always. I'm on a 105 at 11:1 and that's where it ended up.

BUT...I didn't want to compromise. And I'm confident I can tune. And I planned for it.

As a general rule what you posted is correct. If you are buying a custom cam, you should be able to get what you want. The biggest issue I've found is guys call a cam company (any cam company) and act sheepish or unsure of what they have and want, the cam guys go into default mode and start compromising cam timing.

Do your research before you call them, and know what you want. And don't bend on it.
