how much gain with 78m fast intake over ls6? i think i found a pretty good deal on a 78mm.. I cant afford the 90 TB and intake so thats why im asking. Is there a good gain on a H/C cam with just the 78mm over the ls6 intake if the price is right?
Thanks

The 78mm FAST is a good gain going from a stock LS1 intake, but if you already have an LS6 intake, don't expect any gains. Most who swap gain little to no horsepower.

bascially this is a swap for me ls6 and a few bucks type deal.. I didnt want a 78mm or anything other than the ls6, but I was wodnering if there was any gain from the 78mm.
I may just keep my ls6 if there isnt any gain cause I can fork up 1100 for the TB and 90mm

The reason to go with the fast intake is the ability to do a good job port matching the intake to the heads...because of the 3 piece design you can accuratelly line up the ports. I agree that the ls6 is just as good but if you take the time the make the port transition smooth you will gain some flow.
