I sliced my EFI grommet because I didn't want to cut the harness to install it. Most of the connectors should be weatherproof anyway.
Nice piece, what size is it?

Or you could pay $136 for a 90mm LS3 TB on AmazonJust a factory size polished up. Can't beat it for 80 bucks shipped and the one I have is kind of grungy


I believe it should but I'd Google it first.Yes but will that work with the cathedral port heads?

Then send it to VMAX for porting.
Edit: Actually I don't think that will fit on your factory 6.0L intake. Buuutttt, you could upgrade to a GenIV intake and then bolt on the 90mm![]()
Its not 100% bolt on but its worth about 25hp. Here's a write up about it:There is a couple problems, one is six pin, one is 8, there is a physical difference and then the motor is on the wrong side on some years, all this and you still need the correct TAC mod or it will not fully open and with that problem it will go into reduced power mode.
My memory is fuzzy on the details but its not that straight forward.

Everybody knows I want more power, but i thought it moved good with a stock 350 3.08 gears and 31's. The cammed 6.0 4.56's and 35's should be a dang rocket ship.


There ya go, forgive some parts being partially attached, it was a test run after all

Give it a month and I will let it rip and let the horses sing.
