On a 03' 4.8L, I would like to push 300 rwhp/ 290-300 rw tq N/A without spraying or any forced induction and low 14's at around 97-98 MPH. I dont know if I can do it but tell me if these mods will get me close. Comp 212/218 .522/.529 114 cam, Comp 918s, Thunder Racing pushrods (same set up as scream), LS1 fans, exhaust (cut-out if I have to), ASP pullies, intake, LS1 EDIT, 160 t-stat, free mods, and LT's. I think this would be a nice number to have for a daily driver, if you guys have any suggestions let me know, they will be greatly appreciated. I know I might need a TC but I would like to see where the above mods get me first.

 

You should be fairly close to that with those mods. I think you might shy on the rwtq though

 

Yeah.. you should be close. Scream has almost the same mod includint the same cam, he just does not have the lt header and is putting down 272rwhp.
