header install

I was just wondering how much it should cost to get shorties installed or should I brave it and do it myself? I did my catback but this looks alot more complicated.

Re: header install

It's not all that complicated, however you might have issues with rust/etc

Not sure on price, but unless you have a lot of patience and/or tricks up your sleeve (torch?), you might want to take it somewhere's

I put them on my 89 in the driveway with no problems, not sure how much different the strut tower clearance would be on yours, mine came close to the steering shaft (MAC headers) but it cleared it...

Do you still have all the smog pump stuff? If all your bolts break loose, that might be your last hold-up

Re: header install

I did my shorties on my 95. It was a pain to do/fun at the same time (i like turning wrenches). I had to disconnect my steering shaft and remove the metal bar that goes across the k-member. The easiest way to get them out is to slide them out through the bottom. The most difficult part to do is get the headers in place, get the gasket in there and tightening the bolts. The tightening is the definately the hardest because space is ridiculously tight. On the passenger side i found it easier to get at the front bolts from below. The driver side front bolts have the power steering pump interfere but you can still get in there an make it tight, just takes a lot of short turns. I also had to bend my dipstick tube a little bit. These are just some things i ran into, plus some rust but nothing a little penetrating oil couldn't handle. I don't know how much it would cost for a shop to do it but i'm guessing it wouldn't be cheap. Btw, the way to tighten header bolts is to do it initially, warm the engine up/cool down, warm up again then tighten them while hot. They're going to back out and doing this 2 or 3 times should stop that from happening. I would recommend buying the bolts from summit that lock in. They're expensive (like $50) but worth it so you done have a header leak.

Re: header install

hou think installing headers on a stang is hard? try doing it on a camaro that has a freaking 5.7L 350 stuffed nearly into the dash... that is freaking hard... the LS1's are a little easier but the LT1's and 3.8L V6's are a pain... so i am told lol... i wouldnt do the headers swap on my camaro because i would get mad and break something lol... but i would do it on the 79

Re: header install

I probably wouldn't do it on the F-bodies either, their ridiculously stuffed in there....Foxes have more room in the engine bay than sn95 cars. The 5.0 is really stuffed in the engine bay on the 94-95's atleast with clearance on the sides.

done it... didn't have to remove the starter, did have to loosen the drivers side motor mount completely, and loosen the passenger side, and jack the motor up to clear the steering crap

Re: header install

A tip buy some penetrating oil for 5 bucks and put it on all of your header bolts and collector bolts and let them soak for about 24 hours and they will break loose alot easier

Re: header install

without a lift, figure on 4-5 hours your first time - takes some finessing

Hell, I wouldn't even change sparkplugs on an F-body......

Re: header install

personally on some cars it would be alot easier just to lift the motor, its not like you have to take it all the way out.

this is what the dealerships do with alot of new cars in order to change the plug's ( a good example would be the LT1's everyone meantioned)

Re: header install

and that is why the dealerships and auto shops charge so much to do plug changes on f-bodies... they think that if the shop manual says to lift the engine a little they have to do it or it will not work at all... it is easy to change the first 4 on a v6 and the first 6 on the v8... it is the back two that are the problems but those are easily changed from under the car... but if i had the cash to let a dealer do it i would let them just to avoid the hassle but once you get the hang of everything it does not take over 30 minutes top...

Re: header install

/\ Really? Changing plugs on a modular motor with COP's is a cakewalk. 20 minutes max without using electric or air tools.

Yup, that's also the reason why I shy away from advising people putting GT40 heads on their stang, cause finding headers that compensate for the angle of the sparkplugs is few and far between. There just isn't much to choose from, plus changing plugs is a *****.
