Speedway Motors TruRam LS1 manifolds - I can't find any installed pictures I want to see what these look like installed on an engine. After a bunch of internet searching I can't find a single installed picture. Lots of press releases from summer 2011 and lots of links to Speedway's site.
Hooker does it right... tons of pics of their new manifold with all kinds of measurements.
Thanks,
Brian

They're cast? I thought they would be welded tubes. They LOOK like they would fit a few things I own or may own to swap in the future. I have to agree with you about some measurements. Even a picture of them installed on an engine sitting on a stand would give you an idea where they fit in relation to the engine itself.

Apparently they're cast stainless steel. I'm debating on using a manifold and going under my steering shaft or saying eff it and building headers. I know the Hookers will work, but don't care for the tiny outlet.
Need to go under (2010 Camaro doesn't work)... I know 2001-2002 F-body works fine, but looking for cleaner options.
Or just bite the bullet and build some headers similar to the ones Headman used to make.

I emailed Speedway and asked them for better info. I showed them how much detailed info their competitor (Hooker) provided. The sales rep forwarded my questions/feedback to engineering. Will let you know what they say.
Thanks for the update. As a reference, here is the kind of documentation Hooker is providing. Given that you sell a product designed for tight space constraints, I would think any prospective customer would want this kind of detail before purchasing.

Response I received from Speedway:
If they want to sell any of these they need to step up their game. They won't fit in my application as I only have 4.25" between the steering shaft and edge of the block i.e. the dimension where the Hoookers are 3.77". Hookers it is.
Good day,
Thanks for contacting Speedway Motors for your automotive needs. My name is John and I am one of the techs glad to assist with questions and parts selection and your patience is greatly appreciated.
You inquired about a photo of the installed headers/exhaust manifolds for the LS1 and we apologize but currently one is not available. With the many sets of headers and manifolds we only have a couple that are photo available on the web or in our catalog. Normally with the listed dimensions customers can take some basic measurements to insure fit on their application prior to ordering. Below is a list of the dimensions with an explanation of where the measurements are taken. The photo on the Holley website indicates how the headers look when bolted to an engine and with these dimensions you can confirm fit.
Header Dimension A : 4.50 " from the head surface to the furthest out point
Header Dimension B : 8.00 " from the top of the flange to the bottom of the collector.
Header Dimension C : 17.375 " from the front of the header to the furthest rearward point at the collector.
Collector Diameter : 3.00 "
Inlet Size : 1.75 "

If you want a tight set of manifolds, look at the stainless headers from ProComp Electronics. You have to go to their eBay site to find them, but they're extremely compact, and only $200. I just put mine on my '69 Camaro with a 6.0L, and they fit great. I'd looked at the Hooker manifolds previously, and those would have hit my steering box by at least 1/2".

These?

They won't work for my application as I have to clear the lower control arm and get the exhaust out to the side. The Hooker swap manifolds are the only thing that fits other than building headers out the side over the steering shaft. Don't feel like building headers and don't need more power in a hp/weight limited class.

Nope- these.

I can't tell how much you can have them kick out before they hit the LCA, but I can tell you that the inside edge of the collector flange kisses the extra tab on the side of my 4L80E, so that should give you some idea as to how tight they are.

They say right in the notes that you need "shorty" style plugs, and they make a recommendation on a plug that works, which I picked up (which was actually longer than the Autolite plugs that were in my engine previously). I only put a few plugs in to see what the clearance was like, and so far it looks good. I'm using MSD wires with the adjustable-angle boots, and with the boots folded up at a 45, they clear the tubes by about 1/4" or more.

Those won't work... the collector would be basically touching my firewall. I have no trans tunnel room for exhaust... car has side pipes.

1. The FRPP shorties are squared at the end to allow room for the header bolts. I was aware the port spacing is the same, but wasn't sure how I'd round those tubes out etc.
2. The LS1 appears to be wider than the SBF so the clearance between the engine and shaft is a bit less.
3. I didn't want to deal with adding another support for a heim and another u-joint. The car has manual steering so the most direct route is best.
The car is power/weight limited for the class it's built around so I have no need for extra power. I'd rather build headers out the side and over the steering shaft vs. move the shaft around for some other variant of shorty.
End of the day the Hooker manifolds fit with no further mods and should work fine. If the car ever needs more power I'll build headers and sell the Hooker manifolds.

what if you machine the inlet flanges on a slight angle to bring the outlets closer to the block?
Any body got any more pics of these different headers incld stainless headers from ProComp Electronics i keen to see more different types bolted up to a engine as i'm trying to find some thing to fit in my gu nissan patrol, iv made my own but im not really to happy with them and the cast iron hooker ones would fit in there with a bit of angle milling on the facings but i still have a front drive shaft to clear
