I did a 4.6 as well and never bothered with the throttle body, I read up that the stock TJ throttle Body and manifold are already more than capable of flowing enough air for a stroker. I did however spend money on an upgraded cam shaft. I think you are re-using the stock one?

My 4.6 Runs on 87 Octane perfectly fine and is much nicer to drive on the road then the stock 4.0. Even though its not quick by any means.

Nice Jrama, I'd like to know more about your build. I'm not aiming to get the most power possible so it looks like I'm trying to achieve a similar end goal. Good to hear from someone that hasn't had their stroker build turn into a nightmare ;)

Yeah I'm not going nuts with my build so the tbody won't make a big difference, but I figure it's all part of the "incremental upgrade" process where each upgrade starts to take advantage of the other. I will DIY port my head. Dodge put a 68mm tbody on a 4.7 liter engine so I figure it can't hurt to put one on my 4.6 so long as I upgrade the intake, port the head, eventually upgrade the exhaust etc.

I went with the BBK (edit.. had BDS... they dont make TB's lol) TB because the 05-06 went to a different IAC set up and makes things finecky.

Russ is a solid dude and is swamped lately. If you give him a call he will get back to to. kinda like wrangling a cat some days.

I'd prefer not to name the machine shop due to some of the drama with my build. He's good at what he does but its been a crap show. He has access to a torque plate.

Russ did get back to me yesterday. He is assembling a parts list for me. The urgency of my build is completely superficial so I'll give the guy a break, I can only imagine he is a busy dude.

The Grand Cherokee 68mm throttle body that I'm using is the same as found in the 2003+ Dodge Durango or Daktoa 4.7 except that it uses the same IAC as the 2005/2006 Jeep 4.0 and therefore should work fine with the TDS adapter on any Jeep with the newer IAC. I only know this because I picked three throttle bodies from pick-n-pull before getting one with the right IAC lol.

would have been a nice tid bit of info earlier in the build. but...... this has been such an adventure i may have known it but forgot it.. so many things have changed i've gotten to the point i want it to burn or i'll just throw money at it till its 100%.

with that being said Just Empty Every Pocket..... after the engine, its axles, then cage, and then and then and then....
