Twin Turbo '66

Howdy,

I just now found this racing part of the forum, and thought i would stop in and say Hi.

I just started working on my '66 that I call Lucky Sock.

Is torn down, and starting to build the goods after driving it for about 2 years as a daily, 5.7 vortec swap truck.

Will be a twin 61mm Turbo, Aluminum 5.3 LS and Th400 build. Going to be a alot of street driving, some track, and a few trips to mexico here and there for fun.

As of now, just finished up getting the LS built and done and this weekend will start getting it set in the truck and finalize position and get the trans mounted up as well. From there will start mounting turbos, piping intercooler, radiator, new fuel system and all that jazz. It should be an exciting truck.

I personally don't go to Mexico, too much risk with my career.

(Mexico is slang for "acceleration contests" on "public hard surfaces.")

Re: Twin Turbo '66

We got the motor and trans dropped into the truck this weekend. Used new CPP perches, with Solid motor mounts bolted to Dirty Dingo Sliders. The Th400 tranny bolted to motor went in easier than expected. Its on a CPP tubular cross member with Polyurethane mount.

So shes in, and we have a whole lot room for turbo piping, especially since we are going to do a rear mounted radiator with external pump to put some weight in the back as well as clear up engine bay.

More to come!

Re: Twin Turbo '66

Made it out to the shop today after work to work on the ol '66. First had to drill some holes for the new tranny crossmember and get that tight, then i could tighten up the perches after everything was straight.

The FTI stage 4 th400 with a brake looks pretty good sitting up under there!

Next started to pull apart the old fuel system. The line is -6 with like a 250lph pump, and that wont cut it at all for the new setup. So got it all torn out, and dropped the tank. For the tank i need to drain it, and drill a hole for a bulkhead fitting so i have the ability to drain it when i need too.

Since im running E85, and here in the midwest come winter time you cant get E85 for a few months, so need to be able to drain it and get pump gas for when i drive it during the cold.

The New system will be going in soon, a bigger in tank pump at 450lph and -8 line all the way to the fuel rails. sooner or later will upgrade to dual 450's, but single will work while we get the tune laid out and some driving time on it.

Slowly making progress on it!

Currently it has 4.11's with a 275/60/15 tire. Thats probably same tire i will run in slicks, or radials since they fit. But we may leave it, or may regear it for some 3.73's. Havent looked to much into yet, need to do me some research

With the turbos?

Anything 3.0 to 3.50 will work great, I personally love the 3.25's in my turbo truck. With boost, you don't need a deep gear at all and the high gear gets that heat in the pipes for the spool much more efficiently. Awesome build!

3.25's got it, i need to ask my Uncle who has LS turbo as well what his rear gear is to start out with and see. His runs well in the 9's, so would be wise to start there lol

the 4.11's we just through in there to have a little fun with the old Vortec that was in the truck when we bought it haha

Re: Twin Turbo '66

I have done some tinkering on Lucky Sock past week or so, but mainly just wanted to show off me new parts i got. 417 Motorsports out of Missouri makes some badass parts! Owned by Blake Hughes who has an LS Turbo S10, thats won dragweek and hauls some ass. One of the nicest and most helpful genuises you could find.

I got their -8an threaded fuel rails made for my edelbrock intake, which are nice quality and were the same price as Edelbrocks fuel rails. They utilize stock length injectors which is another plus.

The big beauty is their one of a kind designed water manifold block. With the rear mounted radiator and external water pump this easily allows you to only run 2 hoses back, as it is a crossover block. As well as having (2) 1/8" ports on top to easily dump steam crossover into as well as a pressure sensor or something else. It may cost more than just some adapter plates for the block, but you actually end up saving money after not buying as many AN fittings, and hose. Plus it just looks badass so thats a plus as well haha.

More to come, the Truck should go to Chassis shop in the next month or so to get a 8.50 certified Roll Cage and maybe some other work done.

More to come!

Re: Twin Turbo '66

Quick little update and photo dumb on the Truck. Haven't made whole lot of progress as we were waiting to figure out what and who to do the roll cage. Whether we want to do it and take a little longer but save some cash. Or take it to the local chassis shop and have them do it quicker but pay a good amount more.

We ended up deciding we are going to try it out and do it ourselves. My uncle is a good fabricator and welder and has always wanted to try it and see if he has the skills to do so. So im giving him the opportunity too.

First off we knew we needed to fix the frame from previous owner where they cut out the frame and just straight destroyed the front crossmember. So we cut that out, and then started patching up the frame cut outs. As well as we are going to box the frame in that area just for some extra strength, as well as were put in a chromoly bar for the new "Crossmember".

Re: Twin Turbo '66

While my uncle was welding up frame and working on that, i stopped at local yard store and got some 2 3/4" full aluminum round bar to make some solid cab mounts. Cut em on the horizontal band saw and finished off in the lathe so are all the same and a nice solid finish. They will help not letting the cab move at all with the roll cage.

I also was able to finally figure out the accessory drive, and find a belt that will work for it as well. Was a tad tricky finding how to mount and run everything while using an external water pump. Ended up using a tensioner from LSX Innovations that bolts to pass side head. I will clean it all up and get everything painted to finish it out.

Also attached a picture my uncle whipped up for his plan on the roll cage. He has one in his truck and knows what he does & doesn't like. So he added couple extra bars for extra safety and support. It'll cert to 8.50 and we will be good to go. I'm hoping this weekend we can get the main hoop going and start rocking on it. More to come as we build the cage in the coming months.

Re: Twin Turbo '66

Find Super73's thread on his chassis. It was well thought out and looked good. I would blow the truck apart and box the frame and really think about a 4 link. The curved rear bars need to be straight to be effective at that length. Also you will want to ad a sill bar on both sides. I would do what ever you can with this cage that will allow you to update it SFI 25.5D. Some times you dont need the cage for how fast you go but for a stiff enough chassis to handle the power you have.

Re: Twin Turbo '66

Thanks for the reply, and the comments on what your opinion. i'm open minded about it all and will take it into account. This is my first build so im learning and others have done it and have the knowledge and im happy they are willing to help out! I will talk to him and see what he thinks

I guess i should point out i'm not building a full blown race truck either lol yes it will see the track and the occasional race on the street. But its may purpose is to daily drive it to work and i would really like to do Rocky Mountain Race week. I guess i care more about building a fast fun truck that i still drive everyday and on 100+ mile trips. Realistically if it goes into the 9's ill be happy. I may build it more race worth later in life, but i'm doing what i can afford now being straight outta college and paying that off and buying a house haha.

Appreciate all the feedback, it all is greatly appreciated!

Re: Twin Turbo '66

That's coming along nicely. Why in the world did the PO do that to the crossmember?
