*PICS* Lt1 Hsr Design
All I am waiting on is a final price and a dyno showing the gains. I have a pretty radical 355 that is eagrly awaiting this. I have a ton of work done to my intake to get to where I am at currently. I know what my modded intake flows, if this has better flow numbers, game on. Cash in hand!

Can't wait. I working on getting my LT1 up and running good again... This looks like it belongs on top of my next LT1 motor build 
I am still very interested, but the price is a little higher than I was expecting (am I the only one thinking the highest flowing LT4 FI version should be about $600-$700?).
$7XX for the basic bolt-on manifold seems like it will price it above most LT1 owners budget.
Would that be including everything to bolt on?
-Fuel Rails/or modification to use LT1 rails
-Gasket
-Throttle Cable Mount
-Any other conversion parts needed
I don't want to be the cheap *** here, but when the HSR is only ~$350?
I guess I will just need to see how much work is actually involved, because I work with a Machine Shop as a Mechanical Engineer so I have a reasonable idea what machine work costs.
But I still give you HUGE Kudos for doing this!!!

This is more than just throwing A hsr on an lt1. The lt1 manifold is a lot like a mini ram. Now, on a L98 engine, the hsr and the mini ram are just about even when it comes to generating hp with the hsr having a good advantage in torque. With the lt1 starting off with a mini ram like intake, what can we do to the hsr to surpass the hp #s of the stocker and keep killer torque? The answer to that question costs time and money. I wish we could sell it for what edelbrock sells theirs for but there is way too much that goes into what we're making. Edelbrock took a pre-existing ltx intake manifold and instead of putting more R&D into it to make it better performing, they cut corners to sell it cheaper. And look at the power you get from it. We are doing the same but instead of pulling an edelbrock, we are making the hsr better than it is in stock form. Not just cutting it down to fit.
I guess the question is, would you be willing to spend a couple hundred dollars more over the edelbrock for 2-3 times the performance?

Other than the 5hp/tq #s that everyone keeps throwing around, that were done incorrectly (different dyno, only 1 pull with the setup being the same), what numbers are you talking about for the Edel? I'm not For or Against Edel, I just want to finally see some numbers that were done pretty much back to back on the same brand dyno.

I am with GrnDragon; the $7xx price point is a bit too much.
I could see them at $400/$500/$650, for the 3 flavors.
If your base model could flow stock + 30%, intermediate flow stock + 50%, and then on the high end you could do stock + 60%. Then what that does is leave room for the ultra high-end dudes to ask for "custom" work. Thats where you cash in. Each custom job would be specific to the customers car and setup. That also allows you to price your 3 base models at a price everyone can afford. If your goal is to get one of your products on 5%-10% of the cars on the road, then that would be a tremendous amount of work, and money in your pocket. I would assume you could set up the machining to be CNC ,so its repeatable and less time consuming for actual man-hours incurred. Make your money on volume.
Just thinking out loud.
I would love to get one of these on my B-Body.

If this makes a good bunch of power, I for one would say it's worth the money. GGPC is putting alot of R&D into this and that's hours and money. Then all those hours of cutting, welding and machine work.

Amen Paul. There is a lot of work going into this intake manifold. The man has to make some money on the project. 
I have been involved in some of these types of projects and they are very labor intensive. From what I have seen this will be well worth the money.

I wasn't meaning to question any amount of work it takes, I just needed to know where all the money/time was being spent to alter the manifold. If it does work as expected and looks good too I would probably be willing to spend the money to buy it too.
I will just sit back and wait.....
I will just sit back and wait.....
if it proves good power gains id pay up to 900 for one....i mean hell....whats a FAST 90 or FAST 78 go for for ls1s.....i hate it when ppl are like...uh...well this car is old....stuff should be cheap....
mad props for goin this route and lettin us know that ppl still do care about new advances in our old technology
