Compu cams XE268H question

Mopar makes a single spring with dampner
Works great I have used it Mancini sells them .
I would not run that cam with any gears taller then 3:91
It does not really star pulling till about 2800 on.
Plus the lower the c.r. The worse the bottom end will be .
You can install the cam advanced to compensate some .
I hear a lot of people complain about the 292/509
But I think it pulls hard when in the right setup and it sounds wicked !
I have A brand new one I'd sell cheap pm if interested ?
