HO conversion...huge endeavor for me?

Reply #15
yeah its hilarious.
 
i hear tons of people say "i got a 87/88 bird/cat put headers on no problems its a good"  and also lots of rants "this *bleep* car!! the headers wont fit blah blah *bleep* *bleep* AAARGRGHGDG!!"
 
so ive no idea. what do some people's cars frames or shafts twist or move or motor mounts move or something over time and its just enough that headers wont fit? jeez its crazy i dunno who to believe! your site's tutorial was the FIRST point of view i read about it so ive always had that influencing me, so dont worry im prepared. but im still gonna try it, maybe ill be lucky and i wont end up throwing something. :crazy:  so for one thing im DEFINITELY going with some stock stang take-offs from fleabay. why not theres lots of em and there a dime a dozen!

For what it's worth, my '85 had ZERO fitment issues with mustang headers and aftermarket *super cheap* h-pipe. 


Your results may vary. ;)

The stock Mustang headers fit mine with no issues when I used to have the column shifter in the car.I have a floor shifter now,and the 1 5/8 BBKs.But,no problems before.

Yes, I used the Summit brand H-pipe, BUT, it's an 'off-road' no-cats H-pipe, so that may not be ok for your emissions testing.  I do think I've heard of people passing non-inspection emissions with no cats, but, as I said, your results may vary.

oh yes...i have thought about that, i dont want cats!!! but theres actually a place near me that i was told (by my bus driver in junior year of high school actually!) of a place to take the '38 to inspect it because "he'll go easy on ya" so ill go there and he should let me by because yes here in upstate ny we have a visual inspection not a sniffer.
 
cant wait till 2012, then i can do whatever i want with the car and they cant stop me!!!

hey i got a quick exhaust related question--how far back does the summit h-pipe reach? is it the same as the stock stang pipe? or do different mfr's h-pipes go different lengths...? i just scored a set of older 2 chamber flowmasters from a guy nearby (talked to him on corall.net he had up up for sale there) and flow tubes. one is 14" long and the other is 16", i measured em. is this long enough?
 
if not how long are the flow tubes i should have? are the driver's and passenger side tubes still different lengths? just want to make sure i get the right stuff, cuz i think i can get em at a local autohole or something.

Yes, the summit pipe is a direct replacement for the stock piece and the pipes are offset in length where it connects to the flowtubes just like stock is.  I ended up buying flowtubes from MAC Performace separately.  Sounds like you got a good deal on the lers, since the flowtubes are included.

you sure? is the mustang as long as the cougar/bird? id think itd be shorter, thus the cougar would need longer flow tubes/h-pipe/something to account for the difference.....?

I installed a Pypes off road X-Pipe and it fit like a glove,BUT,the flow tubes had to be lengthened about 6 or 8 inches.Our cars have a slightly longer wheelbase.

k thats what i figured.
 
you said "lengthened" were new pipes welded onto them adding to the length or were they stretched or something? can u do that? LOL

The Mac Performance flowtubes I bough must've been extra long, then.  Because even when I slid the ler way on, it's still almost too close to the rear axle.

The H-pipe will be the same length, but I think you can make up the difference by lengthening (sectioning some pipe in) the flowtubes.

hey i just thought of something. the heads i got are bare, as in no valvetrain on them or anything. he did give me the valves and springs though. should i use them or could i use the ones from my car? how about the rockers? can i re-use mine? is there another complicated sub-process to installing the valvetrain? tools i need? i know ill need a valve spring compressor. anything else? (by the way he wrote with a yellow marker numbers on each valve and on the underside of the heads, so i take im to match each valve with its numbered spot?)
 
i searched corrall and found this thread: http://www.corral.net/forums/showthread.php?t=850067&highlight=replace+camshaft and theres a link there to here: http://users3.ev1.net/~voodoostang/headsswap.htm
 
i read both guides, made me feel a little better actually! particularly about the A/C and how that can just swing out of the way. but it turns out that i need a harmonic balancer puller. i think ill be able to get that.
 
but things like the headbolts, i had no idea. great guides. definitely will be picking up a set of those. and the timing chain, is it pretty much guaranteed i will need to replace that? what should i look for? will it have a lot of slack if it needs to be replaced?
 
also what does "painting the harmonic balancer" mean? are the marks for timing on it stamped and you fill the stampings with white paint to make em visible?
 
i hope my lack of experience is showing as this goes further. i figured there would be things that are understood as generally known already by someone doing this. ive never done anything like this, and have little knowledge of these specific tasks. all im saying is any little tips like "do NOT re use ur head bolts" (mentioned in those guides) please dont hesitate to mention, even if it seems repetitive, or if its easier just link me to a site or something.
 
but overall im feeling more and more confident i can get this done and in a timely manner (shooting for a week or less...?)

If you're going to pull the front cover,you may as well change the timing chain.Surely after that many miles,it has wear ans stretched somewhat.If you're doing all of this,do it right the first time.You can get a balancer puller from Autozone with their loan a tool program.You leave a deposit,take the tool,return the tool when you're finished and get your money back.Easy.I'm getting ready to do the same H.O work on the new project car this spring.Take your time and ask a lot of questions so it gets done right.Good luck.
