    Header Collector Extensions: Drag Strip Tuning

    My s bends look very similar to yours. I do have those mounted. Then I have 54 inch of straight pipe, with the mufflers before the axle and turn downs. I have not got them fully mounted. Was waiting on hangars. I did slip them on with it running. It for sure took some cackle out of it. I'm...

    Header Collector Extensions: Drag Strip Tuning

    Subbed. I bought the same mufflers you did, and plan on leaving my 3.5 x 18 inch "s" extensions in place on the collectors, even when racing. Hell, if it doesn't hurt it through the mufflers, I won't even bother taking them off. I have the extensions mounted, and already see the wideband is...

    Notice a difference??

    Stock 340 Manifolds or TTI Shorties?

    you're correct...most long tubes in an A-Body aren't much fun to install. Between the drag link going between the tubes...the low ground clearance...having to take the engine lose. But on the flip side, some of the $ versions that don't go through the drag link, cook the starter. It's a...

    Stock 340 Manifolds or TTI Shorties?

    I think this is a "do what makes the most sense for you" scenario. If you are only driving this on the street...can you feel the approximate 20 top end HP that shorty headers may gain vs manifolds? The engine will certainly breath better, but at the same time, if that takes you a weekend...

    before the axle turn downs

    I had dumps under the car at one point. I have a long gravel drive. It was awful. dumped them in front of the rear tires...slightly better, but really just caused the dust to billow into open windows on the car, opposed to out the back. my blue car is getting exhaust out the rear. I...

    Well that sorta sucked...

    I've pretty much come to the conclusion that if i'm going to pay out the rear for headers...it's going to a chassis shop and someone can fab them up. For the amount of "like a glove" alleged claims that i hear about the big $ fan favorites... i see way more first hand stories of issues such as...

    Well that sorta sucked...

    Was a stock 74 swinger at the time. Ps and all. As stated above, my power steering pump, box, and column remained bolted to the car until the day I dropped the entire k for a tube setup. Only interference I had was a lock to lock turn would cause the pitman arm to touch a tube. I have big...

    Well that sorta sucked...

    By no measure am I insulting Dougs, I'm just surprised at the issues above is all. That brand is simply not one of the 250 i carry directly. Don't go knocking the flowtechs i ran back when i was 16 ;) they worked just fine for what they were. If i had to rip out my column and steering box...

    Well that sorta sucked...

    I had a cheapy set of flowtech's on mine at one point...I literally had no issues you pointed out other than dropping the drag link for the driver side, which is obviously required. Sorry you had all those issues. I guess i'm in no hurry to start carrying Dougs...

    Well that sorta sucked...

    Good lord....i had three sets of headers on my car before I ever had the column out for anything...and the steering box remained until the day the entire k got swapped out. What size tubes are these? I ran a factory box for a year with 2.125 hustlers

    I think I finally need tailpipes. Options?

    thats quite an uphill climb for a fuel line no? i don't know if i have seen a sump mounted that low! I imagine it's working fine if you aren't having any drain back or cavitation issues...but thats against every fuel system article i have ever seen :???:lol

    Header wrap

    Agreed with above posts. Do NOT wrap them. not worth the aggravation. I had a buddy do his and they smoked horribly, and they backed up the heat into the heads....the header flanges would literally glow red because the heat that was radiating...was now confined by the wrap. if you have cooling...

    Heating and bending headers?

    Not a chance...if you can find someone with some welding skills, you might be able to cut the tubes on the bottom, remove about 4 inches..and possibly leave them a slip joint for easy installation.

    73 dart swinger with 360 what manifolds will clear power steering box

    Thats like asking which type of brick you should drop on your car...why not upgrade to headers while you're in there. here's 85 pairs from summit, starting at 120 bucks that'd do the job. http://www.summitracing.com/search/Part-Type/Headers/Make/DODGE/Model/DART/?Ns=Price|Asc
