Any 4.7's with ported and polished 68mm TB?

Wondering how the performance feels and if you feel the throttle more responsive.

Re: Any 4.7's with ported and polished 68mm TB?

mine is either 68 or opened to 70 I dont remember, from Fastman.

so for mods I have K&N63, MagnaFlowCatback, SuperChips91, aand the Fastman TB.

The TB was my last mod of those above but I did notice a difference in throttle response, etc.

Re: Any 4.7's with ported and polished 68mm TB?

I was about to jump on it a while back but i was just not convinced enough to send off my tb to get it ported, and wait for it to come back. Did not seem like it was a mod that would have benefited me. I think the only thing for the 4.7 i can see worth getting at this point are the h.o. cams in my opinoin.

Good to know Rob, i am hoping for better low end out of it, no need for high speed here.

I bought mine straight out for $120 from a vendor on the dakota forum, most importantly i get to keep mine.
A good idea if you don't want to deal with the hassle of removing yours.

Re: Any 4.7's with ported and polished 68mm TB?

I am curious as to whether or not the bigger blade helps on the 4.7. Fastman says 68 is enough, but I'd really like a F&B 72.

Regardless of manufacturer, throttle response and low end drivability is MUCH better on the 4.7 with a ported or bored TB.

I don't think so. any low end loss is masked by the torque converter. But you have to be able to tune for it. SC isn't enough
