Can you recommend any other throttle bodies? So far I've only come across the hughes and the holley and the holley is way more expensive than hughes.

 

There's fastman and another, whose name eludes me right now.

There are some on fleabay even, but check out the seller ratings.


This is all off the cuff, I admit, I don't even know how much the Hughes runs...

The truck has a dual straight pipe and im going to put headers on. Do you know where to find the axle code on a chrysler axle?

 

A bolt, holding on the diff cover, should have a metal tag on it stating the gear ratio that's in it.

 

If it's not on there look at the sticker under the hood. It will tell you if it has a limited slip and the ratio.

 

Four hole injectors may flow better than the current, high-mileage stockers, but, they aren't a performance improvement. The stock injectors point the gas at the back of the nice, hot, intake valves, so, they not only cool the valves, but, the heat vaporizes the fuel.

Unshrouding them at the intake is an actual improvement.

 

So will the stock injectors be able to handle the added air intake of a bigger throttle body and intake?

 

They should. There is some built-in 'overhead' on the flow rates.

 

What do you mean by this?

 

Grinding out the inside of the injector hole in the manifold runner. I think there are pics around somewhere if what it looks like before and after.
