All our motors are is just big air pumps, with the right parts, the more yu can get into them at right mixture and tempature , and have the hot gasses pumped out thru a really good tuned exhaust ,, the better they`ll perform. Granted it with lil over 500 hp @ 5800 rpm`s , i`m so tempted to have my right foot into the loud pedal a bit ,,,,then ??....what freakin mileage.??.....i drive at 10 over speed limit she`ll reward me .
So if we build them or add the right parts to achieve a little more mpg and it works its alllll good

 

Well to get the best out of your truck you have to have it running right. Do a full tune up with Champion Copper plugs gapped at .040, (get some new Mopar or MDS wires, Cap and rotor if you have a 5.2L or 5.9L), a good oil change 10w-30 Mobil One FS.

You can get more out of it if you have it running right in the beginning.


1999<------What other TB's do you do?

 

I consistently do 5.2 and 5.9, 50mm and 52mm tb's and I do 4.7l as well, and occasionally I do the 3.9l. I have ventured off and did some 3.5l chrysler tb's too for the intrepid and 300m's, funny thing is those have just as big as a throttle blade as a 4.7l throttle body. The are both 68mm plates as of 2001 and up. Basically if it has a step down in it I am willing to go in and machine it out. Ah I see you have a V10, I would have to see a picture of one to see what can be done to it.
