LOL, aren't you glad that I'm not rich...if I was, I'd already have all of these parts that I want instead of just dreaming about them and asking tons of questions! I've wanted a FAST LSXrt ever since I read that thread that I linked to...definitely the best gains from an intake on a GENIII truck that I've ever seen

i would go for the L92 intake with L92 heads.. but since u already have 317's, the tbss intake would be a bang for buck mod like u said

Yep, I already have WCCH StageII 317's...honestly, I'd like to some day get the FAST, and am more thinking about how big I should go on the cam without leaving too much on the table with the stock intake. I've been swinging between <224/228 (or 230 on the exhaust), .581/.59x 112 or 114>, and <220/224 .581/.581 112>. Actually starting to lean toward the smaller one and running that until I can work up dough for a FAST, then step up to 224/2xx, or maybe even 228/2xx when that time comes (if it ever does).

Another thing to consider is my exhaust...it's not the highest flow or intended for the highest revs, and I can't afford to change it for a long, long time. I currently have StainlessWorks 1 3/4" LT's, but with small 2.5" collectors, going into gutted cats and a 2.5" y-pipe, into a 3" catback with a DMH electric cutout, 18" 5x8 Magnaflow, dumped over the axle. I'd think that if and when I can ever afford the FAST, that I'd want to go to something with at least 3" collectors and y-pipe, with either dual 2.5's or a single 3.5 with a 3.5 DMH elec cutout....

Lots of plans, just no dough
