Holley high rise- vs - fast composite for ls3
Hey guys I'm considering either of the intakes listed for a daily driver.
Was wondering pros and cons of each heads are ls3 on a LQ9 mild cammed with long tubes. Drivability is a big concern at lower speeds say 2k rpm range that's where I'm at cruising at interstate speeds when converter is locked.
Considering the Holley, it seems to be a better bang for buck opposed to the fast. I also was considering the mid rise Holley for ls3 heads that will be released this 1/4, but also have a deadline I plan on meeting for completion. That pushes me to current production items. A sheet metal is not cost effective or practical for build.
Truck is a Sierra crew cab lq9/ls3 hybrid, with 3200 stalled built 4l65. 411:1 gear front and rear awd. Any other options are considered but have to have 102mm t body options... Thanks!

If you don't mind the heat that the aluminum will hold, then I would run either the mid or hi rise from holley. I haven't heard bad things about the fast LS3 intakes. In fact, I have one sitting on the shelf waiting for me to rebuild my 408. I would rather run a plastic intake on a daily driver since it gets so hot where I live. Obviously there are pro's and cons to each. And you will need to do some work to make the ls3 fast intake to fit

Awesome ^^ how is drivability? Is it a total dog down low? I think with the right setup it would be just fine... And the fast intake good god 900+ for a piece of plastic.. It may be better but the cost of the Holley and it comes with rails and in a truck with zero hood clearance issues. I'm leaning towards Holley at this point more pros then cons at this moment

Well thanks guys! Cam is ordered, I did a lil chamber work on the ls3 heads and unshrouded the valves a bit and milled them .030 to bump compression a bit and I think ima get the Holley. May be having a stepped header made for it idk yet. I got a level 3 monster with a 3200 circle d I'm putting in now so. Things are moving right along I'll keep you guys posted on what it lays down.. It's awd so I'm hoping it gets close to that 500/500 mark I'm shooting for! I speced a proprietary grind just for this combo..
