You guys got me scared of tti headers!

It's a tight fit and the tolerances on these cars are like +/- 1/4". On some cars there's no hammering and tweaking, on others there are. If I ran stock torsion bars with an automatic transmission on my car there would have been no dimpling or tweaking at at all with the Doug's. But I run 1.12" bars with a 4 speed and use a milodon road race pan, so, my options were limited to adding some small dimples for my torsion bars.



I'm using stock spool mounts with polyurethane replacement inserts. I have a V8 spool K frame. I haven't taken a survey or anything, but it seems to me that folks that run spool mount K's seem to have better luck with Doug's compared to TTI's. I'm sure there are exceptions, because with the factory tolerances these cars had there will always be exceptions.

I love the Doug's on my car, I wouldn't buy TTI's again. Just not very impressive for the price, the coating looked like cheap aluminum spray paint. You can get the Doug's from Autozone sometimes with a 20% online discount that they run.



Yeah, ok. And everytime you adjust the depth of the slot you're going to have to pull the engine and headers or drop the K frame while supporting the engine to either get in there with a MIG or a grinder (or both). And you won't get it right the first time, so, you're going to do that a couple of times. Yes, sure, I see your point there are ways to adjust the engine height with the spool mounts. But that's not anywhere near the same league of modification as adding a shim or two under the biscuit mounts. And on my car at least there's nothing that a 1/4" up or down would have solved anyway. But I have a few complicating factors with the size of the torsion bars I run, plus the 4 speed linkage, road race pan, different shape to the flaming river steering box, etc.

Well, I wasn't taking sides pertaining to Dougs vs TTI's, and I stated it was "simple" not "easy". You can get it right the 1st time if You're patient, and as stated some spots
may need a ding or two no matter how well You position the engine & components. I put a 383 in My ex-PoPo Dippy using spool mounts & an A833, and I put a 440 in My
Buddy's '73 satellite (which has a SB specific K-frame in that year) also w/spool mounts. The former I used a combo of early-B and later headers, and the latter has a set
of Hooker Comps and a Moroso 8Qt. pan w/a column shift 727, I built the 3" frt. pipes back to the muffs, then TTI 3" tails..................I nailed the Dippy 1st shot, had to
adj. the Satellite down on the dr. side as much as the pan would allow. Doing anything right takes some hard work, if one is not up for it then leave it alone. The OP asked
for experienced input, Yours has been duly noted, on Your spool mounts the Dougs seem to fit better............................................

Hey I'm not trying to take you down a notch or anything. I just think the way you said it the first time makes it seem like modifying the engine height with the spool mounts would be a piece of cake. And welding up and grinding or just grinding the slot in the spool mounts wouldn't be a big deal by itself, but I thought it was important to mention that the reality of it is that in order to actually do that as part of the header installation process you'd either have to pull the engine and headers back out, or drop the K out of the car (unhooking all the suspension) while hanging the engine in place. At least once, if not more. Because that's the reality of it, and that's nothing like just sliding in a shim.

And yeah, I think it's worth mentioning my experience with both the TTI's and Doug's, because not everyone has actually installed both brands of header on the same exact car. And really, unless you do that you won't know which one would fit any particular car better. Factory tolerances weren't perfect, and neither are the tolerances on the headers, they're not all identical. Throw in different combinations of stock and aftermarket engine mounts, torsion bars, transmissions, steering boxes, oil pans etc. and some combo's will work great and some won't. Personally, even if I knew exactly how both sets would fit ahead of time and the TTI's would fit better I'd rather have to do a little more work and make the Doug's fit because having had both manufacturer's parts the Doug's are better quality. And you can usually get them cheaper too.

How will I see the discount code from
Autozone?

They usually have one for online orders at the top of their website. They did it pretty regularly for a long time, but it doesn’t look like that have one right now.
 
Now that I am looking closely it doesn't even show that they make a set for a 73 swinger.
