Lss3

[69cunningham]

The radiator and support went in recently so I could see how the hoses and intake tube would fit. The 2010 Camaro LS3 upper hose doesn’t work. Oh well.

In this forum, several lower hoses have been suggested for LS swaps, the Gates 20931, 21718, 20687 and UPC 720530602270. The later fit a 93 chevy half ton with a 4.3 liter. I happened to have one of these left over from a Jeep project. It fits OK with a little trimming. I may try some of the other hoses to see if the fit is better.

I just got a flaring tool from Eastwood. I needed it since stainless is difficult to flare. My cheaper tools wouldn’t hold the tubing adequately. The standard Eastwood tool does 45 degree double flairs suitable for brake lines. I also got the 37 degree kit for AN flares.

The tool does a nice job once I discovered how to use it. The 37 degree instructions only describe double flares. The AN fuel lines require single flares.

I decided to do a little body work today. The filler panel is the 38-7621 from LMC.

Very nice project!

I had problems finding a correct lower hose for mine. I finally ended up making a brass adapter to go from the stock radiator to the stock LS hose. Please keep us posted if you find a better fitting hose.
Very nice work on the stainless lines. I really like that setup.
Excellent work on the fuel filler patch. Keep up the good work.

As far as the upper rad hose check out the 2002 Chrysler Voyager 3.3 liter (PN 72044). It worked on a guy's LS3 Nova setup. Seems like the dimensions would fit w some minimal trimming.

Any progress lately?

[69cunningham]

Things are moving slowly. I just got my latest order from Summit, some brake lines and a clutch master cylinder. I should have some pictures soon.

I'm going to get the Voyager radiator hose tomorrow that conman585 recommended. It looks like it will work with an extension in it.

Awesome project!

Here's where I saw it.

Thank's.

A while back I discovered the following pedal installation:

I’m not interested in the Lokar pedals, but am in the clutch master cylinder install. Here’s a picture of my hydroboast.

[69cunningham]

I got the clutch master cylinder part way installed. I used a ¾” unit from Howe Racing (524412). It just fits behind the CPP Hydroboost. I hope the ratios work out.

[69cunningham]

The clutch is finally working. I discovered that the master cylinder didn’t have the stroke that Summit Racing listed. It was only an inch. First I was worried it wouldn’t work. The cylinder bottomed out an inch before the pedal reached the floor. The clutch disengaged an inch higher. Once the pedal stop was installed and the rod re-adjusted, the cylinder bottomed just as the pedal reached the floor.

Your trucks coming along very nice!

[smokinstang70]

Awesome job man...

[mcbassin]

Killer work on the clutch pedal setup. Also love the boost setup! That looks like a quality piece. Keep up the good work.

[69cunningham]

I finally figured out the top radiator hose. It’s made from two hoses and a coupler. The neat thing about the coupler is that it has a 1/8” pipe fitting intended for a temperature gage, but I’m going to use it for the steam port. The engine side hose is from a 2010 Camaro (AC Delco 22736M) The Radiator side is from a 2002 Chrysler Voyager 3.3 liter (PN 72044). Thanks conman585 for the recommendation. The coupler is a 34mm unit from UPGR8 Racing (U8301-3404). The steam fitting an 1/8” NPT X ¼” hose barb from Earl’s Performance (AT984204ERL).

[69cunningham]

Things have been moving slowly over the last few weeks, but they have been moving. The steam vent is done.

There was a set back with the rear end. The pinion has been dripping oil. I had to take it out so the Rear End Shop could replace the seal. I should get it back in the truck this weekend. I hate working on something that was supposed to be done.

[69cunningham]

I got the electronic gas pedal installed. At first, I was going to build a bracket the bolted to the mounts for the original pedal however it didn’t seem strong enough. I removed to old net plate so the bracket could be welded directly to the firewall. The GM pedal pad is not the most beautiful thing. Lokar makes a replacement, but at $115 I think I will consider something else. There might be a way to adapt a stock 71 pedal pad.

[69cunningham]

The rear end went back in today along with the brakes. Hopefully it won't leak again.

Hey 69cunningham, I saw in a post by hart_rod that the 71-72 gas pedal swaps perfectly with a 98-06 truck pedal. See post #22 here:

Nice job so far on your truck.!

[69cunningham]

Thanks Ken-

I saw hart_rod's bracket. Unfortunately it doesn't work with the late model GM electronic pedal that came in 2009 Cadillac CTSV's.

Oh darn.

[rkleypas]

Beautiful build. I dig your attention to detail. Is your ls3 the e rod package? Are you running a stock front accessory package? If so, was any notching required for the ac compressor?
