i would just call Thunder.. you'd get an answer a lot faster than emailing them.. they are great people up there to talk to as well

I will if I dont hear anything after tomorrow.

I have been doing a little research on cams over on tech. and some of the guys seem to pushing cams like this. I have been running my 212 218 for a while now and am itching to try a different cam. I think there is potential for more torque down low while not sacrifising power up top.

Any updates?

Just got word from Thunder that the set up I said above shouldnt have any problems with this cam.

Any mention of valvetrain wear issues? The only thing that makes me really hesitate with this cam is that I dont want to have to swap springs every 20,000 miles

For n/a??

you noted they mentioned your 4.8 setup with milled heads.....any mention of this cam installed on a bolt-on 5.3L?? (CAI, cat-back and headers, tune) ??
does anyone know how much lift is safe with the L33?? this cam has me really interested because of the torque gains. i understand i'd probably need to upgrade springs, pushrods and lifters...i just want to make sure it's good to go and it's gonna do what i want it to do safely....

I was answer over email and I didnt ask because Im going to use PRC springs which are good up to 30k.

I asked them about my setup since no one else chime in with any different setups. This was done over email I would like to add. Its hard for me to call during the day and have a sit down talk, I work 14 hour days.
