hey all i have a forged 347, eagle 6.125 h-beam rods and diamond nitrous pistons -2cc, i have long tube 1 3/4 hookers and home ported heads with stock valves, stock ported throttle body and a ls1 intake and 3.73 gears with a 6 speed and a spec stage 3 clutch. i am running dual 255 intake walbros and 60lb motorons (tuned very well on motor plus i am running a 250 dry shot) all tuning is done with hp tuners by myself and the help of ls1tech.com i have right at 1400 dollars to spend right now and i am trying to decide what to do that will gain the most horsepower for the money n/a. this setup has dynoed 371rwhp at 5800 and 366rwtq at 4700rpm N/A. ok i was thinking about ordering thunders t-rex cam and crane dual valve springs and a ls6 intake to hopefully reach a goal of over 400rwhp on motor. and my other choice was to order a 90/90 combo and stick with the above mods. i would like some other peoples views on a combo that might help me reach the 400 plus rwhp numbers on this budget. i have been on the search button for the past 2 days and have come across alot of great ideas but wanted more opinions before i spend my 1400. thanks guys
