I need some information from some 700R4 tranny guys out there on where to get the 2 cooling lines. I checked with "In Line Tube" and they don't have anything already "Prebent" for the 700R4. Is the Turbo 350 and the 700R4 tranny cooling lines the same (size, bends, area for connections, ETC... ? If so, problem solved and I can just get the prebent Turbo 350 lines! (I don't think it's going to be that easy though) :mad

So I'll probably be buying some straight tubing and fittings and attempting to do it myself. "In Line" want like 26 bucks "JUST TO SHIP" 2 pieces of 6' tubing. :noway: Any national/local places I could go and get some tubing? Any Suggestions??


Any suggestions on where to get some quality tubing/fittings? Should I get about 12 Ft or so to do the 2 lines? Should I go hard line all the way, or insert a small piece of hose close to the tranny like the original Turbo 350 for flex? Are they 5/16 lines. What size fittings (1/4 X 20 NPT?) Double Flared Ends?

Thanks, Bob

I use flared 5/16" brake line sections from the local auto parts store. You can get them in longer pieces with the ends flared, ready to bend. I use 2 long pieces and put a flex hose in the middle.

Now that's an idea. What pressure are there in these cooling lines? Plus they're really not that visible. Where exactly do they run? Tucked in inder the engine near the mounts?

I built a Red 70 SS 454 Sta. Wgn. It was a factory 307 with a 350-T.
I installed a 700-R-4 and the origional 350-T cooler lines bolted up to the 700-R NO PROBLEM !!!!! The Org. 307-350-Turbo. Cooler lines have been on my wagon since 2003.
P.S. a 700 is like a 350-T with an O.D. unit. Also, I removed the " U " shaped shifter from the 350 and attached it to the 700 and you can use the stock shifter.
My engine is a 468--700R-4---3:08 rear= 19.50 MPG
Drove it to Buffalo N.Y. (Can-Am. show) from Pittsburgh, Pa. 276 miles and I used 14 gallons of gas. did not run the A/C and never went over 70 MPH.
At 70 MPH the 468 is turning about 1850-1875.

Install 2 12" lines on the tranny and bend them down like the original. Put 2 flare unions on them and then run 2 more longer, to reach the tranny. With this set up when you go to remove the engine or tranny just loosen the lines at the unions as they will be accessible and leave the short 12" lines on the tranny. With a tubing bender you can bend the 3\8 brake lines to fit.

I heard they were about the same. How/Where do they run? Above the upper control arm, next to the engine or what??? Wasn't sure if was exactly the same line area. My original lines are shot though and cannot be reused. I tried to figure out how the old lines were run though. Man, what a mess. A lot of bends in a short area.

With a tubing bender you can bend the 38 brake lines to fit.

My originals had short stubs out of the tranny, with 8" of hose, then hardlined to the tranny. Works for the engine and trannt removal as you mentioned, but also give it some flexibility in that area. Wonder if anyone had a picture showing the line runs??

Checked local parts house and they have 6' pieces for 7 bucks. AND they will throw in a bender tool to borrow as well. :hurray: I could probably ScotchBrite them down and clearcoat them to make them look like a stainless line.

The stock 350 cooling lines on my 72 mated right up to the new 700. Maybe some slight bending.
