    I know this subject has had the crap beat out of it, but, I'm planning on putting a 440 in my car, and wanted to know who has used them and how they fit, pic's would be awesome. Also, can you use power steering, and 4 speed with these headers? I heard that the stock Z bar worked with no mod's. Any input on these would be great!

    Yes, they'll work with PS. Will come close or possibly just touch the corner of the PS gear box near the top. Grind the corner of the of the box if necessary - no biggy. Or you may have to use one of their 1/4" shims (on a biscuit mount). They fit and work great - especially for street cars.

    You or an exhaust shop will have to fab head pipes.

    Below is pic of clearance on passenger side.

    Oh, and I had to make a wrench to reach certain spark plugs.

    They fit nice, except I do not have power steering.

    I have them on my 70 Gold Duster with power steering and an A-518 overdrive trans. I modified mine by cutting off the 2.5 inch collector's and going to 3 inch ones and ditched the two bolt flange and went with V-band style connectors. Go to my picture gallery to see photos of the modification. I had the dent the driver side header a little to clear the steering box. As noted in previous comments you can grind the box instead. I'm quite happy with mine. Very easy to install and remove, starter not trapped, and all spark plugs easy to change. I drive mine to the track, no trailer. A lot of guys say they will kill the percormance, and I'm sure they cost some power. My car has run a best of 11.48@116. Go to my YouTube channel; Doosterfy and see my videos.

    Cool, thanks for the info guy's, I am pretty sure that's the route I want to take, they look like the best fit for these car's, and having power steering is a must for me!

    I've got them on my '73 Duster with 383 and power steering and their mounts and headers were the best investment. So easy to put in and beautifully engineered. Can't praise them enough...

    I had them. The fit cant' be beat. You can install them with the engine bolted in place.

    The performance can be beat. Going to a big tube header in magazine tests showed almost a 1/2 second 1/4 mile time.

    My issue with the performance is that when I went to the TTI's my engine simply ran better and I'm not talking about power. It idled better in several ways, it ran cooler as well. The fitment of the TTI's suck IMO. So take your pick. Fitment or performance. If I had to do it again (with stock suspension) I'd go Schumacher.

    Add: I used TTI 440-200's (2") along with their 3" system which has some issues of it's own that COULD easily be corrected.

    I totally agree with you. Not being able to keep the power steering was the deal breaker for me on the long tube headers. I get lots of respect at the drag strip when I drive in off the street. Having power steering makes a car WAY more enjoyable a, safe and easy to live with.

    How quick is your car. Do you drive it plenty on the street or is it a race car?

    Mine is pretty much going to be a pro street setup, probably never see a drag strip, so the 30-40 hp loss is not going to be a deal breaker going with these vs TTI . I just know that these car's are a bitch to put a RB into, and I'm trying to make it as painless as possible.

    I reckon you've answered your own question there dude. Schumacher's look great and are a beautiful fit. You wont regret it!

    The Schumachers work ok for the track and yes you do loose some HP. My car is running in the 11.60s with the Schumackers and just using cut outs. I do drive mine on the street.

    So the Schumachers vs. TTI long tube debate has come to the same conclusion again. Yup, they cost some power. As we all now know the little Schumies are perfectly adequet down to mid 11s. If you're trying to push harder than that, then yes the pain in the ass, can't have power steering long tubes become necessary. It all comes down to what you are going to use the car for. I have to wonder how many guys are dealing with the long tubes and only running 12s or slower. I'd call those guys nuts. I also know that Womanator has run 10.90s with the Schumacher headers with a race motor in a 3500# A body. If your not going to race the car then its a no brainer. You won't regret running the little headers, trust me.

    just over 500hp depending on the tune, headers and intake used.

    I only drive it on the street and I drive probably 2-3 hours a week.

    I used to think that. Then I built 2 of them. If you know the quirky parts it really isn't any harder than a small block.

    I like them.This one was a 451 stroker with Schumacher Tri-Y's 11.90's street and strip. I like them. They will be going back in a 63 Plymouth Belvedere in a up comming project.

    Good to know, I'm a newbie to the bigblock A body thing. I'm sure I'll have more questions when I get to putting this beast together.

    I have them in my 69 Barracuda with 440 and power steering (MSD mini starter). I just removed the driver side to replace my steering box. I was able to drop the header without jacking up the engine or removing the starter. I did disconnect the steering column and pull it into the car a bit but, I had to do that anyway to swap out the steering box.

    That's freakin awesome, we had to lift the motor on a small block duster to even get TTI headers on that, I was figuring that the steering column was going to have to come out anyway. I am planning on putting in a different steering coupler from speedway motors, my buddy did his, and it works awesome! He say's it the best $50 he spent on his car!

    What is the benefit of using that coupler?

    Using that coupler will eliminate the ability of the steering column to telescope with the body flex. Supposedly causing the column to destroy itself. At least that's what E booger says in Mopar Action.

    Well, maybe, maybe not! I have a coupler on mine, car is frametied, with over 60 runs on the car, manual steering still works ok.
