Upgrading intakes soon, curious as to which would be better for my application. Stroker Ls1, ported and milled 243s, 238/246 112lsa. NA build for now, procharger in later future. I've heard the Holley will give a tad more power on the top end, while the fast has steady power and torque all over. Opinions? Test results? I have searched but haven't found much.

Short version, neither.

Get a NNBS intake and call it a day. For the cost to HP, it can't be beat.

You pretty much already know the deal. Broad power go with the fast, more top end go with the Holley.

FAST came out with different length tubes though so you can tune the power range with them if you want adjustability.

It's hard to beat the FAST and the MSD atomic for broad power.

If you want all the power go with Frankenstein, but be ready to be in debt till your dead to afford one.

Sounds about right. Curious about how guys are doing harness tucking with the fast, the Holley is nice because you can run the harness underneath it. Also the steam tubes eith the fast, how are people running those?

I have ran both, the fast had a little more low end which is expected.
the lsxrt was a pain in the *** to seal right tho, never could get it to seal.
put a hi ram on and all my problems went away.
but a nnbs would probably be just fine for you.
