Re: LT1 GenV swap
Clint, I was looking at getting a set of the DD Mounts but was quite honestly put off by the hard corners inside. I was going to do the same thing you are doing and Design and find someone to make me a Ported set. Then I figured I would do exactly like Holley did and design an adapter for their LS brackets to the LT.
Like I said in my last post I have used the LS brackets several times and have been extremely happy with them. Quote:

Re: LT1 GenV swap
Toddoky,
I just read my last post.... Boy that sounded demanding. I was extra leg happy to see you working on this. Do you guys have a target release for this kit. Will we be able to purchase it in components, as the LS kits are offered. Thanks |

Re: LT1 GenV swap
That is good to hear I am looking forward to these. Saves me the effort of having to figure it out on my own.

Re: LT1 GenV swap
Got the pump hung...
https://imagizer.imageshack.com/img921/923/TXgnHk.jpg belt alignment looks good so far. Not sure if I will hang an idle pulley off if the power steering bracket to get more belt wrap around the balancer or not. The pump came from ebay forget which year silverado, think it was 06+.. only chose it cause of the windows in the pulley. Could compare it to the 99-02 pump that's in my 87 swap once it gets removed. As far as the tensioner, I found the tensioner Dirty Dingo uses, same one Magnuson Superchargers uses in some applications... heavy duty 8 rib application tensioner.. wonder if it's too much tension on a 6 rib belt. Still looking for a 6rib version of that same style tensioner, basically pulley is flush with the mounting base of the tensioner.. Clint |
Re: LT1 GenV swap
site is frustrating with this 30 minute editing policy.. so, another post
this is basically what I'm going to aim for as far as fit/form/function except the top of the pump reservoir more parallel like my picture.. damn aesthetics :) http://goatbuilt.com/wp-content/uploads/4405-4408-1.jpg after a little searching, this tensioner seems to be the exact same as the 2014 Silverado, but tensions the belt the opposite direction... but the tensioner base is not flush with the pulley, like I had hoped for. If it happens to be the same as the Silverado's, even at a 1/4 plate bracket would be right at the edge if not over the edge of the pulley from my eye balling things.. might make a trip to the autoparts store and compare if they have these in stock. I doubt they will order a part just to let the customer see it... clint |
Re: LT1 GenV swap
Got the power steering mocked up. Just need to cut out the front bracket and triple check the last changes. Just need to draw up the spacers and have the a machine shop make em
https://imagizer.imageshack.com/img923/351/qYmMTm.jpg Pretty satisfied with the look, incorporated an idler just to get more belt wrap on the crank. I might make the decorative holes a touch smaller but there there for the artistic touch. Pump is placed lower than the highest point of the intake, and as close to the block as possible.. almost like a ls 5.3. Got a promising 6 rib tensioner, research paid off so far, it's identical to the HD version mentioned earlier but only 6 rib width. Ironically uses the same pulley as the LT.. I could go as far as testing the tension by hanging weight from the pulley just to see since I plan to make 5 sets of these brackets and sell 4 of them. Alternator bracket nearing completion. Header flange is almost mapped out, just need to adjust 1 port.. seems easy but takes many prints to get it exactly spot on, like the water pump adapters. Close is good, exact is better:) Clint |
Re: LT1 GenV swap
Not bad at all for first try..
https://imagizer.imageshack.com/img924/1865/jUjVjF.jpg only to add a notch around one of the water pump bolt boss is.. other than that, power steering bracket is done, just need to make it in metal, then buy a box of washers to get the belt centered and go for round one at the machine shop. I'll wrap up the alternator bracket mock up this weekend. Clint |

Stock truck intake doent have a provision for vacuum port's. The car lt1 has a port iirc. But no need to buy it if the vacuum pump fits between the frame rails without mods so why not keep it for the brake booster and in the trucks application vacuum ac controls. Expecially for the guys that do cams. There's hydropower option, but again more parts to buy. No worry about lack of vacuum with either option. To me, be silly to delete the vacuum pump only to by a electric vacuum pump or retrofit hydroboost. The way the intake is molded... it seems someone would have to cut into it to make sure they get the right spot to get the vacuum source. As far as DOD... im sure most people swapped or not remove that feature. But the beat thing about swaps is the aftermarket support :) Clint |
Re: LT1 GenV swap
Your logic sounds reasonable for your application. I know that the pump won't physically fit in many of the typical GM car swap applications, so if there is no suitable take-off point for vacuum on the truck engines (I've not seen one in person yet to know) then an alternative option will need to be employed for them.

Re: LT1 GenV swap
Got the alternator brackets drawn up. Going to swap the tensioner and idler locations.. think it will look better, also allows use of the factory tensioner...

Re: LT1 GenV swap
Looks good.
Keep up the good work. I personally will be going the Holley LS bracket direction as I will be running Vintage Air and am unable to run a factory compressor. I have no concerns with keeping the alternator on the passenger side and have no need for a vac pump with manual disc brakes. I do have a driver side Holley adapter mocked up so I can check fit and possible interference when I get the engine in the frame. Posted via Mobile Device |

That is, they do not work with variable displacement compressors. Like the ones found in a lot of modern vehicles. I could possibly use a sanden low mounted on the passenger side. Posted via Mobile Device |

Well here is my mock up adapter on the engine. This is basically so I can get the LT in the frame and make sure the accessories are not going to interfere with any of my porter built suspension parts....

Re: LT1 GenV swap
Think i got a winner..
https://imagizer.imageshack.com/img923/6186/c77JMo.jpg Satisifed with everything, gonna find some plate, cut em out and then start measuring for the spacers. Clint |
Re: LT1 GenV swap
With the new spacers will this bracket work with the Corvette balancer?
