So i took the headers off my 2001 z28 and was going to put them on my 99 trans am. the ta has 853 heads... the headers are dynatech 1 5/8s (i think) long tubes...

heres where the car god said F U... once i got the old manifolds out, the pass side header fit up and all the holes alined just fine, the drivers side not so much, had to hit the bottom of the header the get it past the floor pan, now that its up in there the holes arent even close before it hits the steering shaft and the coolant temp senor!!!!!!! I also had to take off the oil filter to get it up in there and now the header looks like it covers the area where the filter goes... I just dont understand why they fit on my camaro and dont fit on the trans am.

Please if you have any ideas or suggestions feel free to chip in.. Im ok with ordering new pacesetters, i just wanna know if i need to order something different so they fit. Thanks Guys

 

bump... anyone ideas

 

Could they possibly be warped?

 

no they were just fine on the camaro... they just dont fit? i dont know whats the deal

 

damn that sucks! i cant remember if i had to take out the oil filter to get the dynatechs in on the 98 or not. definatly didnt have any problems. idk what those heads look like compaired to the others so idk if its that. how much diff are the heads?

 

they should just swap over theres no difference in the floor pan from what i know.
depending on brands you might have to pull the stearing shaft and try unpluging the coolant sensor.

 

i have heard of guys having to unbolt the sheering shaft to get them in

 

the heads are stock... just 853 castings... yea just called dynatech and they suggested i go under the dash and losein the column. and see if that helps... ill let you guys know. thanks

 

so the steering column didnt make a difference.... were thinkin maybe now that my motor mounts may be wore out and making the motor sit lower... anyone wanna chime in? thanks

 

i myself never had to do motor mounts so i dont know how much of a diff its gonna be but i know there probly isnt to many options. i say go for it

 

I had to remove the motor mount pedstal

 

^^^^^^^ at his name......

 

remove MM pedastal..........raise engine..........works everytime

 

Just remove the steering shaft...its one bolt.

Did you cut off the casting tab on the back of the block or is it not even hitting that?

 

no i did not remove the tab? its only hitting the steering shaft.. i know its only one bolt it hits so bad that if i take it lose and bolt the headers up i wont beable to bolt it back together... tryed it.. i ordered new motor mounts today... i think there weak and its causing the motor to sit lower.. i took measurements off my camaro and the trans am motor sits 1/2 in lower... so thats where im at now haha

 

only a 1/2 inch? do you really think thats gonna make up the difference?

 

well i dont know what else it could be... they fit just fine on my camaro and dont on the trans am.... everyone i talked to says a 1/2in is a lot.

 

new poly mounts in... and i measured it and it did raise it little over half inch... hopefully when i put the headers in this time everythings good... i miss my car!!!

 

oh man good luck with that. i know how you feel cause i just installed my pacesetters and had a big problem. had to send the car away for a few days. but when i got it back ohhhhh boy im still lovin it!

 

You were going to want poly engine mounts anyway. It was better to put them in now rather than realizing later that it's almost required to keep the exhaust from hitting the floor. Good move, and good luck.
