just finished intsalling my new coated pacesetter headers. took 2hr to install. my pass header hits my under body badly and my driver header is so close to the brake lines and brake line brkt bolt that if engine was to move stud would go through header, brake the brake lines and pass head would just crack and propably brake against body. also driver header is sitting above tunnel brace possably y pipe would not even go on. i just installed this engine poss my problem is the new poly motor mounts? i called summit they said they are the right mounts. i installed them correctly the clam shells closed with no problem. summit stated poss bad weld job on header? they will send a new set but who want to remove and reinstall again. any ideas?? thanks in advance for help

 

long tubes or shorties?

 

sorry long tubes

 

nobody??? ttt please help!!!!!!!!!!!!!

 

is it poss trickflow heads? or poly motormounts have engine to high?

 

I had the same problem with afr 210 and tpis headers, wrapped a heavy nylon strap around header and used a large bar pulling from underneath (drive on hoist) my headers collecters were hitting the floor bent them down about an inch and a half. No problems after that.

come on guys i really need some help here. should i remove the poly mounts and reinstall stockmounts . their is no way i could bent headers that much.
nobody here every ran into this. iam stuck in the middle of this install

 

Did you install both pass and driver side mounts?

If so then the stock mounts should lower the motor some.

 

i did install both driver and passenger. if i switch back to new stock mounts caqn they handle 800 hp sc? i though poly mount were used by everybody here? should i try a diffrent company poly poss? thunderracing sells a
diffrent brand. mine are energy suspension

 

are you running a poly trans mount? if yes, what brand?

 

same company put all three mounts in at same time. i though is was my trans mount so i unbolted the trans mount and let down a bit. if i let the trans down 1-2 inches then the headers would be ok

 

hmm....

just a lightly tall mount isn't your whole problem.....
