need help with 5.3 direction

well guys the more i read, the more i wonder if my truck will put out the times i want.....of course we all start with a goal and the goal keeps changing. Last time out at the track with my truck it had: Volant CAI, Efans, Flowmaster exhaust, 4.11's, 4L65e with HD2 shift kit and vette servo. it made 260rwhp/284rwtq.. with the local tracks not so good prep best i could get was 9.05 with a 2.00 60 foot in the 1/8.

I have in my room : 226/229 .569/ .572 112 lsa cam, patriot gold dual springs, 7.4 pushrods, pacesetter LT's.33 lb injectors

What Im looking at geting : Circle D 3200 stall, HSW Plate kit, Tru trac, intake swap (either ls6 or tbss),new heads, and possiblely UD

my question is, with my current cam , what would be the best setup NA, FI, or n2o?? i dont plan to bore the 5.3 out, or swap a 6.0 in, i was thinking with it being a occasional road trip truck spray would be better for power for the track, BUT i do realize that your cam affects if your setup works best for FI or n2o. ALSO if anyone who has done a intake swap and has been dyno or track proof the swap helped please post that.


really needing help because i dont want to waste money buying a plate kit and it not work good with my cam
