[1973GTO]

I have a 1973 GTO. We pulled the stock 400 and totally redid it. The engine is back in. I have a set of Dynomax ceramic-coated headers that test-fit fine when the engine was outside of the car.

We could not get the car high enough (jackstands only) to snake the headers in. I'll have to tow it to a muffler shop and have them do the whole exhaust system.

QUESTION: I'm hearing from some people that I may have to remote-mount the oil filter becasue the headers won't mount past it once the engine is in. If that's the case, I'd have to tow the durned thing somewhere else and have that done, then back to the muffler shop.

Anyone ever have this happen? Again, it's a 73 GTO and Dynomax headers. Every muffler man I talk to won't commit to anthing but this answer:

"Bring it on in and we'll see if we can do it."

I'm going to attempt to post a pic with this post (never tried it before)

Looks like you've got plenty of room in the pic. I don't think it will be much different in the car. Its the header that keeps the filter from going on and off not the frame or anything. I would take it to the muffler shop with a filter installed. Chances are it will be O.K. If not you can probably unbolt the filter adapter from the block to change the filter or to install a remote set-up. Good luck.

Have a set of Dynomax Ceramic coated headers on a 68 bird. You can remove the filter, But it will be tough and a mess on the headers even if you cover them . The filter will be a lot cooler and much easier to change as a remote. Why not change it now and not have to fight with it in the future. Adds life to the motor keeping oil cooler.Just make sure you use the proper size hose, prefer braided, and always prime the external filter.

i have a 73 lemans that i put hedman headers on. i had the same problems. had to put the car on a lift to get the drivers side one in. i don't think you will have any problems with the oil filter , i don't. it is a little close , but not more than a half inch closer than the y-pipe was. you will get messy changing the oil though , and some will drip on the headers , good excuse to take it out and burn the oil off!!

also forgot to add that if you have a column shifter , when you put it in low , it might hit the header , had to take my linkage and heat it up to bend it a little
