It looks like ICT Billet has a pretty good answer to the power steering question and at a much more reasonable cost compared to the others. The only issue I see is that the pump appears to be put on the wrong side of the engine requiring more hoses across the front end.

I just dont like the coolant hose routing, nor the power steering on the passenger side.. when said and done the front end will be simple and clean.. once everything is put together. Since i ordere a few more of the adapters, 5 sets total, ill likely make 5 sets of alt and power steeeing pump brackets as anotjer solution for others.

Yeah, that I can agree with. We have a '15 in the driveway (my wife's current demo vehicle) and I crawled around it a bit trying to ID major components. The thermostat hose is a straight shot to the radiator but the one coming off the water pump is a mess. Down to the bottom of the rad on the drivers side but then across to the passenger side where it looks like it tees and then goes who knows where. I'm really interested in what you come up with.

I thought I'd let you guys know that Holley will soon be releasing an LT FEAD system as well and it is based on the use of an LS water pump and uses the existing Holley LS alternator/PS pump components/brackets also. It was previewed at LS Fest last weekend and I can post a photo of it next week if you guys want to get a look at it.

That would be much appreciated! Thank you in advance...

Did it keep the vacuum pump? Hope so.. can't wait to get my ls-lt water pump adapters in and offer the rest up for sale ..only 4 though.
Can't find anything linking a lt1 to a ls fead setup but it looks like it would or could clear a vacuum pump.

No, the vacuum pump was not retained as it won't physically fit in most LS swap applications. The pump is only used in truck applications to augment the vacuum signal when the engine is operating in cylinder deactivation mode, so if will not be needed by someone that is not interested in utilizing that function in their swap.

Good to now .. wonder where they are drilling and taping the hole for vacuum. Be interesting to see the holley setup.

Got a reply from Holley today, there is no LT accessory drive at this time..just want to keep the thread up to date.

Yes that's correct, the Holley LT accessory drives are in development at the moment and not yet available.

Are you allowed to post the picture? I think I read you work at holley correct?

Sure, I can post a photo; I was waiting to get access to the engine to be able to take one. Yes, I am the design engineer at Holley who is responsible for the development of all the Hooker LS engine swap system mounting and exhaust components.[IMG][/IMG]

Thanks for the picture. What's the solution to a vacuum source? Drilling and tapping the truck manifold or electric pump? Will there be other fead setups or just this one pictured.
Thanks Tod,
Clint

I'll have to check on the answer to your vacuum source question. I think this system will be it for the LT1 engines and we are working on a different system for the supercharged LT4 engines as well for release next year.

Looks like the brackets were reused from the ls fead... are the head bolt layout the same? I'm still puzzled why they decided to move the alt to the driver side, it would require a separate harness to extend from the original location to the new.

That's a good observation on your part, the brackets are the exact same ones used in the Holley LS FEAD drive set-up, which are adapted to the bolt pattern of the LT engine by means of the adapters in-between them both. This configuration was beneficial in keeping cost in check so that pricing will close to what the LS set-up is. The alternator position won't be preferable by everyone, especially those using a stock take-out ECU and wiring harness. For those going with an aftermarket EFI system like those from Holley, then the connections needed are just as easily made as if the alternator was mounted elsewhere. I know our beloved GM trucks are the focus of this forum, but there are many more applications Holley makes swap parts for that require configurations or designs that are not necessarily optimized for our trucks.

Toddoky I am down for this setup, I have run several of the Holley LS kits and band for the buck they are the absolute best "budget" kit available in terms of form and function.

I want one and want more information on how this all works.

As soon as we get closer to launch of the system I will be sure to post more information on it.
