FM13 is in! Got it installed today. Upgraded from a TR224/112lsa.
Cam specs are: 230.7/232.3 .595/.585 112lsa
Cam pulls noticably harder in the mid-upper rpms over the old cam.
Driveability is actually better(still on TR224 tune also).
I can drive at 1500rpms in 6th and it doesn't surge like the 224 did.
Overall I am really impressed with the cam.
Look for new dyno #'s sometime next week

I've also been toying with the idea of swapping a FM11 or FM13 inplace of my TR224 but I'm gonna wait and see how the new heads work with my current cam. Down the road I may go the FM way but that will be the easy part as changing the cam is easy when you don't have to change the valvesprings.

It is kinda choppy. A different kind of choppy than the 224 though. Definitely not like stock. Sounds real good at idle through the cutout. I think I might have my tuner lower my idle also to give it just a little more chop, gotta intimidate those stangs at the stoplights!
