I have been reading some conflicting information on this topic.. for example the thread below. The flow numbers clearly show the l76 intake as superior, but the dyno on this thread shows the l92 on top. Any insight? I might just be overlooking something.

lots of confilicting info. 2 things to ponder are the l92 has longer runners and the ls3 is a variation of the ls2 which dont flow that flow good so i am leaning towards the l92 being better. a buddy, chevrolade also tried both and swapped back to the l92 with a 227-235 comp lsr cam. just my 2 cents from previous knowledge and experience.

Ls3/l76 intake is not good at all on a truck , I had mine on for about a week .... Went back to the truck l92 and worked better like it did before.
I never got to dyno before and after but I did feel a loss in my take off with the ls3intake , one thing it pulled good to 7300 rpm , but so did the l92

Does anyone have a stock truck 4.8/5.3 intake vs ls1/ls6 intake comparison or dyno results?
