LS6 intake vs. Ported Fast 78 My Vette has 404 RWHP with a LS6 intake. I have a new ported Fast 78 (uncertain of who ported it. Was bought on EBay a year ago.). Will I benefit from using the Fast intake along with the fast fuel rails? I also have some new FIC flow matched 42 lb. Injectors. The car is a 2000 with ls2 243 heads, Lingenfelter gt1 cam, LG longtubes, ATI underdrive, yella terra 1.7's, Vararam cai, yank ss 3600 and 3.42 rear. Thanks for your input.

You should definitely pick up some power with the FAST, especially with your mods. Even if the 78 was unported it's been proven that it is a step above an LS6, now whether it's worth buying over lets say a FAST 90 or 102 is another topic
Just did this swap i have a Ported 78 and i picked up very little to be honest but the curves improved the whole rpm range and like to stay a little stronger uptop... My tuner said im way outflowing my stock camshaft and thats why i didnt really see too much gain. My stock injectors are at 90% duty cycle so thats my next step along with a bigger cam and probably have to go bavk to stock rockers cause i have 1.82's. Car made 370whp and 380wtq stock heads and cam. You will benefit if you have a cam and supporting mods. I did the 78 cause j could keep stock TB for now and if i want i can swap the upper shell for a fast 90 one day !
