I was planning on putting a gt2-3 cam in because I plan on buying a d1sc next summer, but in the meantime I would like to take out a few 03 cobras and maybe a viper or two. I already have a set of cnc'd 853's,918's,titanium retainers, qtp's, and will get a ls6 intake to swap and port my throttle body all at the same time, but figure I could pick up another 20 horse with a more aggresive cam like a fm13 and will work with my 918's. I know I will lose a bit of boost with the bigger cam, but since I'll already be pushing the 500 rear wheel horse barrier with the blower, blowing #7 piston will be a matter of time anyways untill I get my 408 so losing some boost wouldn't hurt till then. I don't really want to get a tune right away untill I get hp tuners, so I'm not sure if going with a fm13 or similiar will require a tune as the gt2-3 doesn't. Sorry about the long post but I did alot of search's and couldn't find a similiar situation. Oh ya, going catless. And the heads will be milled twice, once before, and slightly before installation, so about .050. What would you do?

 

Thunders TRak cam...awesome cam

 

never heard of it untill now, just went and checked it out, probably sounds nasty which I wouldn't mind, but I'd like to stick with my 918's and not get a tune yet. Thanks for the reply.
