the header just barely fits on the passenger side b/c the flange is against the frame and and that makes it leak ive stuffed gaskets in there for a temp fix. but i need to fix this bout the only thing i know to do is heat up the bends of the header and bend them till they fit or notch the frame.. anyone had this problem before? is so what did u do?

 

that flange can rotate a little to give you more clearance, if not dent the frame rail or put in new motor mounts if yours sag, etc etc

 

ya i rotated it that didnt give enough space need just alil more you say dent the frame? would that be better then notching it out?

 

yes take a ball peen hammer and just give it a whack, it'll bend in the amount needed no problem, don't cut the frame rails over the cheapest headers known to man.

 

You need new motor mounts. Did you replace the v6 mounts when you added the v8? you shouldnt have to dent anything.

 

ya i replaced them i dont think that the v6 motor mounts would work at all...its probly just these cheap headers..

so it looks like im gunna have to dent it a good bit are you talking about heating it up with the torch and denting it? or just beating it to death till it fits? lol (sorry i dont do alot of metal work)

 

If you dent a 1 1/2 inch header you might as well not run it. I had the same headers and they fit fine.However, They didnt add any noticable performance at all and raised my under hood temps in the process. I had this problem wiith a set of heddman headers and when i replaced the squishy old motor mount with a poly mount it fit fine.

V6 mounts fit the v8, I had to use them a few years back when I was in a pinch.

 

im talking about denting the frame not the header and i doubt that bushings will help its not too high or too low its just too far to the left (passenger side) and headers do give more power if what u had on it was old manifolds, sounds better too lol

 

if it's more than 1/4" you have some issues.

 

I wouldnt go denting your frame for a set of 100$ headers. If the flange is the problem why not grind it down a little?

 

i dont think its more then 1/4 but its not like im modifying a 1st gen frame lol i wouldnt dare lol im just wonting things to work this car is just a toy not a every day driver. ill just dent the frame it should probly be fine after that.
