Guest zthang43 Posted June 28, 2002 Share Posted June 28, 2002 Check these out. Anybody used these? Since they hug up against the block they would work well for Z cars, and they look kinda cool. Sanderson Custom Exhaust Manifold Quote Link to comment Share on other sites More sharing options...
Guest zfan Posted June 28, 2002 Share Posted June 28, 2002 I think Jim uses a pair like that if Im not mistaken. Pretty cool. Are they 1 5/8 or 1 3/4" primaries? Mike Quote Link to comment Share on other sites More sharing options...

Guest RisqueRace? Posted June 30, 2002 Share Posted June 30, 2002 I would have to say that ...yes they are expensive. No they dont match 97 lt1 ports exactly(thats what I am installing) and I am not looking for mega tube size cause you don't need it for a street car in my opinion. BUT,they Fit perfectly. For a stock or mildly modded 97 350 LT1 auto in a 77 280 Z they provide lots of clearence on the steering side and the pax side. perfect dump location and angle also. I am relocating the knock sensor to the first engine mount bolt forward of the block drain location (JTR mount Setup). I welded a pipe fitting to a mount bolt and screwed it in and screwed in the knock sensor. They do weigh as much as the stock 97LT1 manifolds. It made my setup EASY. I'll try and answer any more questions you guys have on these. It seemed way easier than the custon header thing. Bruce Quote Link to comment Share on other sites More sharing options...
Dan Juday Posted June 30, 2002 Share Posted June 30, 2002 Looks like two bolt holes are missing. Any problems with leaks? Quote Link to comment Share on other sites More sharing options...
QWKDTSN Posted June 30, 2002 Share Posted June 30, 2002 I think they're just obscured in the picture by the #1 and #7 primary tubes... Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted June 30, 2002 Share Posted June 30, 2002 The ones I used weren't cast. They were bigger tubes too and while the port matched GREAT they didn't fit on the driver's side. The Rewarder headers I've got now supposedly don't fit onthe passenger side but DO fit on the driver's side. I'll test fit them myself when I've got some time and energy - need to do the CVs still dang it. Supra tuning is eating my time up and I've been pretty lazy lately too Quote Link to comment Share on other sites More sharing options...
Guest RisqueRace? Posted July 1, 2002 Share Posted July 1, 2002 To answer your question Dan, yes, they are missing two bolts. They are cast iron and have 3/8 thick flanges. Sanderson emphasizes that NO gasket is required and only a thin film of high temp rtv is required. I cannot answer on wether they leak or not cause I am not running yet. Some day soon If I have a problem with this product I will post it. So far I am happy with the product and have faith that a cast "manifold" will seal just fine. It is a stout flange and casting.

Mikelly Posted July 1, 2002 Share Posted July 1, 2002 I have seen these up close and personal. My former neighbor had them on a 55 Chevy. You can get them in 1 3/4 and yes, the two bolts are missing and didn't cause ANY problems.. He used them with a roots blower type setup and they are awesome... VERY good alternative. I thought these were the units BLKMGK bought, and I'm glad to hear they weren't... Yea, they are pricey, but if you see them up close, they look sweet...

DavyZ Posted July 7, 2002 Share Posted July 7, 2002 Long (dankinzle) used them on his car and he said they were a bit heavy if I remember. Nothing else negative I recall. Davy Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted July 7, 2002 Share Posted July 7, 2002 I can see them not leaking. What causes the leaks is the different in expansion rate along the header flange and the header bolts in a cast head. It moves around alot when it gets hot. Also with chevy's siamesed ports (well not really but the two exhaust ports in the middle) put more heat in the middle of the flange. I've heard that simply putting a slit between each pipe on the flange (between the single front tube and just before the back tube) allows them the movement where they won't leak. Sounds logical to me. Another is to slightly enlarge the bolt holes as they get farther away from the middle, only 1/32-1/16" bigger is supposedly enough to help on a thin header flange and to allow some movement. One thing I really like about cast manifolds, it kills the ringing the headers do when they're struck with the exhaust pulse. Sounds like no big deal, but it almost sounds the difference to my ear of a car with slightly out of adjustment lifters that are too loose and one that is adjusted properly, its a ticking sound, sort of, thinwall headers make.

Guest RisqueRace? Posted December 9, 2003 Share Posted December 9, 2003 Hi All, it's been a long slow road on my project but I am now up and running since aug 03. I said I would post when I had personal experience on the sanderson cast manifolds. here it is no problems with leakage at all nice and quiet...ie no ringing from exhaust pulses fit is perfect, even with a relocated GM a/c compressor on the right side. 97 LT1 setup. tons of room on the left side. Easy hookup to remaining exhaust and allows excellent locations for o2 sensors just below the exit flanges. negatives are pricey weight Bruce I have to add that mine are coated, I wish there was a bit more prep to them before the coating but the coating is holding up just fine.

Mikelly Posted December 10, 2003 Share Posted December 10, 2003 Thanks for the input... These are still on my list of "Must Haves" and since they come in 1 3/4 I"m all over them like stink on Poo! Mike Quote Link to comment Share on other sites More sharing options...
Zerrari GTO Posted December 15, 2003 Share Posted December 15, 2003 Sweet it is! I just made a post on 12/8 looking for high-flow cast iron manifolds. I,m building a Velo Rossa kit and want to keep as mush noise and heat under that fiberglass bonnett as possible. I almost became a coated header convert but these things are just what I was looking for! I've got aluminum heads, intake, etc. so I don't mind some extra weight. Thanks for the post!!!
