I went to JEGS, the guy on the phone gave me a listing for Hedman Headers. Part number 89516 for ceramic coated ones. I asked about Hooker, he said the they had them but only 90 day warranty, dont want that. The Hedmans are shorties, but I dont really care because he said shorties are good for low RPM Horsepower and Torque, like towing. How do these sound?

 

No 1st hand experience with shorties in this particular application. I would say that they would definitely be alot better than the stock manifolds. From comparisons I have seen in other cars, the long tubes are far better than the shorties. My opinion, if you are going to go to the time, trouble and expense, get the long tubes.

L and L headers from the bronco graveyard would probably be about the same money and they are long tubes.

 

Alright then, long tube it is. So torn apart on this decision. Can never get a succinct decision. I am easily persuaded. Some headers have weak falnges, some have 5/8 think ones thay require no gaskets. Some are ceramic coated, some are not, some are long, some are short, air injected, no air injected. Very confused. How would bronco headers fit mine, I have the 460

 

What does it mean by straight axle? I have hubs in on my front wheels, other than that its one sold axle right across? They dont have one for me if its not straight axle. Says with no straight axle.

 

It sounds like you have a straight axle.

Bronco Graveyard is the name of the business, which does not limit their parts sales to Broncos

 

Yeah, I will keep looking, But nothing coming up. If I got the long tube headers, what are some exhaust designs i can make. Can you have two cats? So I could run true duals? So I can run two pipes straight from each header? Pr could I dtich the cat completely, how easily would it be to have someone install cats back before inspection? WOuld an exhaust shop do that for me?

 

Okay, first, you need to check your local emmissions about cats, some states check, some don't. If they do, I would recommend high flow cats instead of the hassle of having someone put one (or two if you run duals) every time your inspection is due. I do not have first hand experience but I don't think it will be a large performance loss with the high-flows. Second, solid axle is just as you had described, a one piece axle, it would be a short tube on your driver's side, the differential, then a long tube on the passanger's side. The reason this is important is because other EFI 460's came with the TTB dana 50 up front, that's an independent front axle (if you can call it that). Lastly, again no first hand experience, but I have heard shorties were better for high RPM power, not lower as someone told you. The long tube headers are much better for the low end torque you would need to get that truck moving. Perhaps someone with more knowledge then myself can speak up and confirm, but that is been what I have read many times over.

Hope that helps,

but what difference is shorty? y wold ppl make them if it doesnt make sense to? all my people who said they would install headers for me said they only want to to install the shorties, because long tube ones are hard, rarely fit exactly and are to close to the transfer case. Howcome there all bitchin out, and howmuch power wont i gain by going with the shorties? Wont puttng any type of headder help? What size would the manifolds be considered?

 

You answered your own questions, shorties are made because their is a demand. One demand is the added performance over factory manifolds, but the limitation of space (like you said, the transfer case). Additionally, like I had mentioned before, what I've read states that shorties are better for high RPM performance, again, there is a demand for top end performance over low end. For a better understanding of why there are even such things as headers, I would recommend searching the board for threads regarding it. I'm not one who can explain this with enough details to convey the point correctly, but needless to say, it involves back pressure and trying to remove as much exhaust gas from the head as possible so on the next exhaust stroke, that gas gets moved out instead of being backed up from back pressure and left in the combustion chamber. Once it's left, then you have less air/fuel mix that can enter and there for, less power. Again, I know there is a lot more to it then that, as well as those who argue for the benefit of some back pressure, and then it gets real technical, but that's about all I offer. Again, this is just my understanding and is not being stated as fact, an engine builder would be better suited to answer this.

Sorry I can't be of more help, I do recommend doing some research and seeing what others have to say other then myself.

Momo, you have been a great help, and one of few who have actually takin the time to help me out on this dilemma. I called around some more to get some info on he shortie header from hedman. The guy on the phone said that shortie headers are good for low end power, like towing or slamming the gas on a 1/4 mile run. He said long tube offer more variations in all power bands So, I am just gunna get these and never look back. Going to with two high flow cats, then two ultra flow welded performance mufflers, out the bac, and be happy. Its not like i am being a cheap ss. This system will be $1,200-1,400.
