Mine are 2.13" and are NOT sleeved, done by my machinist. I can take pics if you like to show you, and mine also drive like normal Ben. That is odd that only a .07" diff would be that touchy off idle, but I guess so. Nice pics Ben, damn, those must be from the CF Vault days huh?

I mean it comes out to roughly what... 10% difference in area at any given throttle percentage? Depending on cam and setup i believe it. Ive seen 850 carbs be super touchy or super lazy on extremely similar setups making similar power so it really can depend imo.
I think "touchy" is subjective; I think many would think that the 2.03" TB's were "touchy" on my SBC 400...but I loved the throttle response and strong pull vs. throttle application, though. I wouldn't have changed it and wish my current 'Vette had similar behavior.

Well ill be damned. Didn't you know you can unlock mega ultra powah simply by upping TPS voltage? That throttle response will hold you back in your seat while you try to reach for your sunglasses you forgot to take off the dash.
In all seriousness I did play around with it on my cousins GTA (why test on mine when i can test on one I don't have to worry about breaking?) I do recall upped voltage by a bit did tip in better... this was a couple years ago now and I had heat exhaustion at the time so my memory is a bit fuzzy.
And I define touchy as an ever so slight bump on the throttle makes the whole car jump... I'm talking like brush the pedal and you end up a thousand rpms higher... this one car was just plain stupid..
You guys think one of those flex hones in say a 1-1/8 size ramed through the runner would be a benefit? I haven't done much of anything since the last time I posted photos. I want to but every time I look at it I get nervous... I have recurring nightmares of filling a cylinder with water. 😂
I think the small flexhone will act like extrude hone of a sorts and only remove what's really burred imo. What do you all think?
I don't think it'd get into the corners.
I think the abrasive would get clogged with aluminum right away and become ineffective. Keep grinding! Shy away from the floors if you're worried about water.
I've got a spare manifold I can send to you, if you are super worried about it. Shipping cost only. I tell ya though; epoxy will fix a hole, no problem.
lol, well if all else fails I'll happily send you my old intake.
I did use it to test my blaster cabinet (glass beads).
i had the pressure a wee too high to start, but it has a nice uniform finish.
been thinking about trying out porting it for fun, but I'm preoccupied with a new to me Tahoe, and I'm learning all about LS engines....
Its about to get a new oil pump and a mild camshaft.
Also, i love the 6l80.
my C4 needs one.

I know but have you seen my luck? Extrude hone is only a day trip away though.

get you a 6l90 lol. How many times did you rebuild yours now?
If I'm being honest I wish the Renegade was a viable option at this point but mine isn't going to work and it doesn't sound like production will ever start again. The design and parts I selected were all based around getting a renegade that was good. I don't think I'll ever see the max potential of the combo even with a tissue paper stocker sadly.
3M cross buffs are the ****.
For the Larger ones, https://www.ebay.com/itm/3M-Standard...1/292145275844
That link will get you started, different grits are available.
Shipping looks high, but buy a bunch at once and the shipping levels out.
(That seller is good)
I also got some pretty long shafts for the crossbuffs on ebay....
So the 383 I built for the company truck is being pulled and given to whoever wants it... 4 bolt main, dished pistons factory roller... I'm interested but I don't think its much an improvement over what I have now. Plus I need to put my heads on it because the stock vortecs are just alright by comparison lol. I could really tax the intakes woth that. That truck currently shifts around 6200 so... hmm...
So I made some more modifications... I measured the upper lip to upper lip length of my renegade and my stock unit. I decided that I could tilt back the inlet some more...
So I started grinding... and grinding...
Around ArounI blacked out... When I came to my last text said grinding the eff out of this, race on!!! And I saw this...
Then I figured what the hell I could clean up some..
And finally more.
And then... I added in the humps.
I'm going to blend them by hand with some sand paper but otherwise, I'm happy with what I have now. I trimmed back almost half an inch from the roof of the inlet which I believe will allow more circulation inside the plenum. The dynk will tell but I feel this is the best I can do with what I have. Hopefully soon.
....at some point.
