Thumper cams or Stage II SPR cams.

I am not really worried about the idle as much as the lift and duration....I am about to order some gears and the cams from you as soon as my engine builder calls me back and lets me know if these will work with my setup.

check and see if you need the Comp Phase Limiters....I have the BBR Lock Out Sprockets and would rather stick with them since they were $400 and allow no VCT movement.

Sounds good man

I dont plan on running more than 12psi to be honest probably not even that much. Only looking for about 450rwhp. No more than 475rwhp as my bottom end is staying stock for a while. the exhaust on the brenspeed video the stock exhaust? does sound kinda quiet. Any other vids of those cams in action? I am looking for the lopey sound but the profile has to mesh well with FI. Brenspeed will be doing my car becuase they are only 4 hours away from me, hopefully when I got the cash saved up they will have something to fit my needs and desires.

Get the same setup I have. I got the 127500's and they are supposed to have a very rough idle but be a pretty good setup for FI. They are not classified as a FI cam but the specs are so close they almost should be. I'm running 12 psi and after talking with 07stanggt for a while I decided to go ahead and grab those.

Since you have the locks outs you dont need limiters. they are accomplishing the same thing
